Computerised VSP & HDT Apparatus (Product Code: SLE/ET/05) is a heated-bath testing instrument used to find the Vicat softening point (VSP) and heat deflection temperature (HDT) of plastics in polymer testing and quality-control laboratories. Loaded specimens are heated from ambient to 300 °C at 120 °C/hour or 50 °C/hour while sensors with 0.01 mm resolution follow them, and 2 to 6 stations can be specified. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, among its test and measurement instruments in India.

Specifications

What Is the VSP & HDT Apparatus Used For?

Both tests show how a plastic behaves as it warms under load. In the Vicat test a flat-ended needle rests on the specimen under a set load, and the bath temperature at which it penetrates a specified depth is taken as the softening point; in the HDT test a bar is loaded in bending, and the temperature at which it deflects by a specified amount is recorded. The microcontroller shows both results directly, and the PC software plots penetration or deflection against temperature.

Material suppliers, moulders and polymer courses use these results to compare grades and judge the temperature limit of a moulded part. Choose the heating rate your method requires, build the load from the 5 g to 2000 g weight set, and zero each sensor before heating begins. With several stations, specimens from one batch run side by side under identical heating, which makes the unit a productive choice among polymer laboratory instruments in India.

What to Specify When Ordering

• Number of stations, from 2 to 6
• Heating rate required: 120 °C/hour, 50 °C/hour or both
• The loads your method needs, so the 5 g to 2000 g weight set can be checked against it
• Whether a PC and printer for graphs and reports should be quoted (confirm with us)
• Quantity and delivery location

Static and Kinetic Friction Tester (Product Code: SLE/ET/06) is a motorised coefficient-of-friction instrument used to measure the force needed to start, and then keep, a sled sliding over a film, sheet or other flat sample in packaging and materials testing laboratories. A 200 gram sled is drawn at 150 mm/minute, readings go up to 9.999 kg, and static and kinetic friction values appear directly on the display. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for buyers of laboratory instruments in India and abroad.

Specifications

What Is the Static and Kinetic Friction Tester Used For?

Packaging films, laminates, papers and coated sheets must slide neither too easily nor too reluctantly on filling lines and in stacks, so their coefficient of friction is checked routinely. In a typical test one piece of material is held flat, a second piece is fitted to the 200 gram sled, and the sled is pulled across at a constant 150 mm/minute; the force needed to break it free gives the static value and the steadier force while sliding gives the kinetic value.

Quality-control labs use it to accept incoming film batches and compare slip additives, while engineering students use it to see the real difference between static and kinetic friction. Keep the sled face and templates clean, avoid touching the test surfaces, and let samples settle to room conditions first, since dust or handling can shift the reading. On the computerised model, the RS 232 link and interface software let results be kept on a PC.

What to Specify When Ordering

• Standard digital-controller model, or computerised model with micro-controller, RS 232 communication and PC interface software
• A PC to run the interface software, if you choose the computerised model
• Any templates needed beyond the three stainless steel templates included (ask us)
• Quantity and delivery location

Inclined Plane Tester (Product Code: SLE/ET/07) is a tilting-plane friction instrument used to determine the coefficient of friction between film and film, film and metal, and film and glass in packaging and plastics laboratories. The plane rises at 1.5° to 2.0° per second beneath a 750 gram sled measuring 4 inch × 2 inch, and two stainless steel templates are included. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory equipment exporter from India serving domestic and overseas buyers.

Specifications

What Is the Inclined Plane Tester Used For?

The inclined plane method finds static friction without a force gauge. The sled, faced with the sample, rests on the plane, which tilts steadily at 1.5° to 2.0° per second until the sled starts to slide; the tangent of that angle is the static coefficient of friction between the two surfaces. Because the instrument is intended for film-to-film, film-to-metal and film-to-glass pairs, one set-up compares a packaging film against itself and against the surfaces it meets on machines and shelves.

Film converters use it to set slip specifications and check production batches, while physics and engineering courses use it to show the angle of friction on real materials. Fit the film smoothly to the 750 gram sled without creases, clean metal or glass surfaces before each run, and repeat on fresh sample areas before averaging the slip angle. Laboratories that also own the horizontal-pull Static and Kinetic Friction Tester can compare the two methods directly.

What to Specify When Ordering

• The material pairs you will test: film to film, film to metal and/or film to glass
• Extra stainless steel templates or a spare sled, if needed (ask us)
• Site supply (listed: 230 V, 50 Hz, single phase)
• Quantity and delivery location

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, based in Ambala, Haryana. It supplies the Inclined Plane Tester to flexible-packaging firms, film extruders, polytechnics and university laboratories in India and international markets, often together with other friction and packaging test instruments.

• Friction Slide Apparatus — a teaching apparatus on sliding friction.
• Inclined Plane With Accessories — a physics-lab inclined plane for teaching forces on a slope.

Explore the Testing Equipments category for more instruments.

Frequently Asked Questions

Which material combinations can the Inclined Plane Tester measure?
The Inclined Plane Tester is intended to determine the coefficient of friction between film and film, film and metal, and film and glass, so a packaging film can be checked against itself and against common contact surfaces.

How fast does the plane tilt?
The plane of the Inclined Plane Tester tilts at 1.5° to 2.0° per second. A slow, steady rise lets the sled start sliding at a well-defined angle, which is then used to work out the static coefficient of friction.

What are the sled weight and size?
The Inclined Plane Tester uses a 750 gram sled measuring 4 inch × 2 inch. The film sample is fitted smoothly to the sled face before each test so that contact with the counter-surface is even.

How is the coefficient of friction worked out?
On the Inclined Plane Tester, the static coefficient of friction equals the tangent of the plane angle at the moment the sled begins to slide, so a steeper slip angle indicates a higher-friction pair of surfaces.

How does it differ from the Static and Kinetic Friction Tester?
The Inclined Plane Tester finds static friction from the angle at which a sled slips, while the Static and Kinetic Friction Tester pulls a sled horizontally and reports both static and kinetic values. Many packaging laboratories use both methods.

Who supplies the Inclined Plane Tester?
The Inclined Plane Tester is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to packaging, plastics and teaching laboratories in India and international markets.

Heat Sealer (Product Code: SLE/ET/08) is a table-top laboratory sealing instrument used to make controlled heat seals on plastic films and flexible packaging samples for seal and package testing. Two temperature zones are held by an auto-tuned PID controller up to 200 °C with 0.1 °C resolution, and a pneumatically moved jaw closes against a fixed jaw to form a 150 mm × 20 mm seal. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to packaging laboratories and colleges looking for laboratory instruments in India.

Specifications

What Is the Heat Sealer Used For?

Seal quality depends on temperature, pressure and contact time, and a laboratory heat sealer lets each of these be repeated from one sample to the next. The operator places two layers of film between the jaws, the pneumatic jaw closes against the fixed jaw, and the heated zones fuse a strip 150 mm long and 20 mm wide. Because the PID controller works to 0.1 °C resolution, seals made on different days can be compared with confidence.

Packaging developers use it to find the lowest temperature that gives a sound seal on a new laminate, and quality laboratories prepare seal strips that are later pulled apart on a tensile tester to judge seal strength. Start low and raise the temperature in small steps, keep the jaw faces free of melted residue, and let the zones stabilise after every change. It also suits film and pouch exercises in engineering and packaging courses.

What to Specify When Ordering

• Mains supply at your site (listed supply: 230 V, 60 Hz, single phase, 15 A)
• Compressed-air availability for the pneumatic jaw (discuss with us)
• Whether the 150 mm × 20 mm seal size suits your sample format
• Quantity and delivery location

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab in Ambala, Haryana, supplies this heat sealer to flexible-packaging developers, film converters, packaging test laboratories and engineering institutes in India and international markets.

Expansion Apparatus (Product Code: SLE/H/17) demonstrates the linear expansion of solids by turning a very small change in a bar's length into a visible pointer movement. An expansion bar sits across the top of two cast-metal uprights: one end is fixed, the other rests beneath a friction pointer that moves along a scale reading 0 to 90 as the bar lengthens. It is used in school and college heat lessons, and it is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a physics instruments supplier to institutions in India and international markets.

Specifications

Typical Use

With the pointer noted at its starting position, the teacher warms the expansion bar with a flame moved steadily along its length. Because one end of the bar is held fast, all of the lengthening appears at the free end, which drags the friction pointer across the 0 to 90 scale. Students record the pointer movement as heating continues and then watch it respond again as the bar cools and contracts. The demonstration makes a good starting point for discussing why railway lines, bridges and pipelines are designed with room to expand.

The cast uprights and paired support rods keep the bar steady during heating, so the reading reflects expansion rather than wobble. Heat evenly rather than at one spot, allow the bar to cool completely before handling it, and keep the scale area free of soot for clear readings. As a demonstration model for the physics lab it works well at the front bench, where the pointer can be seen by a group gathered around it.

Manufacturer

Jain Scientific Equipments Private Limited manufactures the Expansion Apparatus in Ambala, Haryana, and markets its equipment under the ScienceLab name to schools, colleges and distributors. Visit our company profile for an overview of the business.

Melting Point Apparatus Simple (Product Code: SLE/H/18) is a very simple device for determining the melting point of amorphous solids. It consists of an aluminium cylinder with an obliquely drilled hole at its top that holds a thermometer; a thin layer of the test substance is sprinkled on the top face, the block is heated gently, and the temperature at which the substance melts is read straight from the thermometer. It suits introductory chemistry and physics practicals, and it is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of its school chemistry lab equipment for India and international markets.

Key Details

Typical Use

The block is set on a stand above a small, gentle flame and a thermometer is slid into the oblique hole so its bulb lies inside the aluminium close to the top face. A pinch of the powdered sample is spread in a very thin layer on that face. As the block warms, students watch the powder closely and note the thermometer reading at the moment it turns to liquid. Because aluminium carries heat quickly, the top face and the thermometer bulb stay at similar temperatures, which is what makes a direct reading possible. For substances that soften gradually, it is worth recording both the point where softening starts and where the layer becomes fully liquid.

Heat slowly as the expected melting point approaches, clean the top face between samples once the block has cooled, and use a fresh thin layer for each reading so results can be repeated. Its simplicity makes it popular as low-maintenance lab equipment for college and school practical rooms where a quick, visual melting-point check is needed.

Manufacturer

The apparatus is manufactured by Jain Scientific Equipments Private Limited, trading as ScienceLab and based in Ambala, Haryana. Registered with the Ministry of Corporate Affairs under CIN U29309HR2020PTC087597, the company produces its range at a licensed factory in HSIIDC Industrial Area, Saha, Ambala (Factory Licence AMB-ONLINE-CHD-J-414). More detail is in our company profile.

Conductivity Apparatus (Product Code: SLE/H/19) lets students compare how well six different metals conduct heat, side by side and under the same conditions. It carries six metal rods — one each of copper, iron, lead, aluminium, steel and zinc — fixed horizontally through holed rubber bungs in a sheet-metal body, so all six can be heated together and their behaviour compared at a glance. It is widely used as physics lab equipment for schools in India and abroad, and it is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a science apparatus manufacturer in India.

Specifications

Typical Use

One end of every rod sits in the sheet-metal body, so all six are heated from the same place at the same time. A common classroom method is to coat the exposed lengths of the rods with a thin film of wax before heating; as heat travels outward, the wax melts back along each rod, and after a few minutes students can see which metals have carried heat furthest. Copper and aluminium usually lead clearly, while lead and steel lag behind, giving an easy-to-read ranking that students can record in a table and explain in terms of thermal conductivity.

Having six metals in a single fixture makes this a stronger comparison than testing rods one at a time, because the heat input is shared. Keep the rods clean and free of old wax before a new run, use the handle to move the apparatus while it is warm, and let it cool before storing. Teachers building a school physics practical set for heat topics often keep it alongside a simpler strip-type conductivity demonstration for younger classes.

Manufacturer

This apparatus is made in Ambala, Haryana, by Jain Scientific Equipments Private Limited, whose products are sold under the ScienceLab brand to education and training institutions. Learn more in our company profile.

Measuring Vapor Apparatus (Product Code: SLE/H/20) is a high-pressure steam apparatus in which water is heated inside a closed pressure chamber at constant volume, so that liquid and vapour settle into equilibrium and the steam pressure can be measured across a temperature range of 100–250 °C. From those readings, students determine the heat of vaporisation at various temperatures and study the behaviour of real gases and vapours. It is intended for college and university thermodynamics laboratories and is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a laboratory instruments supplier in India serving international markets as well.

Specifications

Typical Use

In a standard experiment the chamber is heated in stages, and at each stage the class waits for liquid and vapour to reach equilibrium before recording the temperature and the steam pressure. Repeating this across the 100–250 °C range produces a vapour-pressure curve. Plotting the natural logarithm of pressure against the reciprocal of absolute temperature turns that curve into a near-straight line whose slope, through the Clausius–Clapeyron relation, gives the heat of vaporisation; comparing slopes over different parts of the range shows how that value changes with temperature.

Because the chamber works above atmospheric pressure and at high temperature, the apparatus belongs in supervised college or university sessions. Follow the operating instructions for filling and heating, wear eye protection, and let the unit cool and depressurise fully before any handling. It fits well into physics lab equipment for thermodynamics and heat-engine courses, giving students measured data on real, non-ideal vapour behaviour.

Manufacturer

Jain Scientific Equipments Private Limited builds this steam apparatus in Ambala, Haryana, and supplies it under its ScienceLab trade name to teaching and training laboratories. See our company profile for more about the company.

Related Laboratory Equipment

Apparatus that supports a thermodynamics and pressure-measurement syllabus:

• Thermoelectric Effects Apparatus — for studying how the temperatures in such experiments are measured and controlled
• Calibration of a Pressure Gauge — teaches how pressure readings are checked against a reference
• Pressure Measurement Bench — broader practice with pressure-measuring devices
• Safety Goggles — eye protection when working near hot, pressurised equipment

Further apparatus is listed under Heat.

Frequently Asked Questions

Over what temperature range can steam pressure be measured?
From 100 to 250 °C, with water heated in the closed chamber at constant volume.

What quantities can students determine?
Vapour pressure as a function of temperature and, from it, the heat of vaporisation at various temperatures.

Why is the chamber kept at constant volume?
In a sealed chamber the liquid and its vapour reach equilibrium, so the measured pressure depends on temperature alone — the condition needed for a clean vapour-pressure curve.

Is it suitable for school classes?
It is better suited to supervised college and university work because it operates at high temperature and above atmospheric pressure.

How is pressure read, and what power supply is needed?
Our listing does not give the gauge type or electrical requirements. Please contact us for the full datasheet before ordering.

Can a calibration certificate be supplied?
Calibration paperwork is not part of the standard listing; discuss any requirement with us through the contact page.

Do you ship to institutions outside India?
Yes, we supply universities and distributors in India and international markets; warranty terms are confirmed with each quotation.
