Specific Gravity Bottles (Product Code: SLE/CE/78) are borosilicate glass density bottles used to determine the density and specific gravity of liquid samples in civil engineering, chemistry and materials laboratories. Offered in 10 mL and 25 mL (approx.) capacities, each has a capillary stopper seated in a ground 10/18 standard taper joint that reduces evaporation. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Specific Gravity Bottle Used For?

The bottle is weighed empty, then filled with distilled water, then with the test liquid, and the capillary stopper is pushed home each time so that surplus liquid escapes through the capillary. Every fill therefore holds the same volume, and the ratio of the liquid mass to the water mass gives its specific gravity. Because the bottles are unadjusted, each one is first calibrated by weighing it full of water at a known temperature.

Students use the method to compare liquids such as oils, solutions and liquid admixtures, and to see why temperature control matters in density work. Handle the bottle by the neck to avoid warming it, wipe the outside dry before weighing and keep each stopper with the bottle it was calibrated with. As borosilicate laboratory glassware in India, the bottles stand up well to routine washing and drying.

What to Specify When Ordering

• Capacity: 10 mL or 25 mL (approx.), or both
• Number of bottles of each capacity, for example one per student group
• Whether spare bottles for breakage should be included in the same quotation

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM for these specific gravity bottles. They are produced at the company's own licensed factory at Saha, Ambala, Haryana, India, so buyers deal with the maker of the glassware rather than a reseller.

Frequently Asked Questions

What capacities do the Specific Gravity Bottles come in?
Specific Gravity Bottles (SLE/CE/78) are offered in 10 mL and 25 mL (approx.) capacities, both with a 10/18 ground standard taper joint and a capillary stopper. The larger bottle suits work where plenty of sample is available, as small weighing errors matter less.

What does unadjusted mean for these specific gravity bottles?
Unadjusted means the Specific Gravity Bottles are not set to an exact nominal volume. Each bottle's volume is found by weighing it filled with distilled water at a known temperature, and that calibration is then used for every liquid tested in the same bottle.

Why do the Specific Gravity Bottles have capillary stoppers?
The capillary stopper lets surplus liquid escape as it is pushed home, so the Specific Gravity Bottles hold the same volume on every fill. The ground standard taper joint also seals the neck, reducing evaporation while the bottle is being weighed.

What glass are the Specific Gravity Bottles made of?
The Specific Gravity Bottles are made of borosilicate glass, which copes well with laboratory chemicals and with washing and drying. Keep each capillary stopper with the bottle it was calibrated with, because swapping stoppers can change the calibrated volume.

Who manufactures the Specific Gravity Bottles?
Specific Gravity Bottles (SLE/CE/78) are manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory at Saha, Ambala, Haryana, India. Schools, colleges, testing laboratories, dealers and importers can order them direct from the manufacturer.

Brass frame sieves (Product Code: SLE/CE/79) are full-depth laboratory test sieves used to grade aggregates, sand and soil by particle size in civil engineering and materials testing laboratories. The range covers 200, 250, 300, 315 and 450 mm diameters, with stainless steel wire cloth or tinned steel perforated plates, and sieves of the same diameter nest into one stack. They are manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM, at its own factory in Ambala, India.

Specifications

What Is the Brass Frame Sieve Used For?

Sieve analysis is the basic grading test for aggregates and soils. A stack of sieves is arranged with the largest aperture on top, a weighed sample is placed in the top sieve, and the stack is shaken by hand or on a sieve shaker. The mass retained on each sieve is weighed and expressed as a percentage to draw the grading curve used in concrete mix design, road material selection and soil classification.

Perforated plates usually cover the coarser aggregate sizes and wire cloth the finer fractions. Stay within the listed loads — up to 1000 g on a 200 mm sieve and 3000 g on a 300 mm sieve — so that particles are not forced through an overloaded mesh. Brush the mesh clean from below, never push particles through by hand, and dry the sieves before stacking them away. Looked after this way, a sieve set from an engineering lab equipment manufacturer gives repeatable grading results across many student batches.

What to Specify When Ordering

• Diameter: 200, 250, 300, 315 or 450 mm
• The aperture sizes you need, and whether each is stainless steel wire cloth or tinned steel perforated plate
• Number of sieves per stack and number of stacks for your laboratory
• Whether the sieves will run on a sieve shaker, so the diameter suits the shaker
• For the 450 mm size, confirmation of the frame material you require

Automatic Marshall Stability Test Machine (Product Code: SLE/CE/81) is a 50 kN bench-mounted compression frame used to determine the maximum load (stability) and flow values of bituminous mixtures in highway and civil engineering laboratories. Its data acquisition and control unit sets the platen speed from 6 to 60 mm/min, plots the test graph in real time and calculates stability and flow automatically. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory equipment supplier in India.

Specifications

What Is the Marshall Stability Test Machine Used For?

The Marshall test is a standard step in designing bituminous paving mixes. Compacted cylindrical specimens made at different binder contents are conditioned and then loaded to failure at a constant rate of deformation. The peak load is recorded as stability and the deformation at that peak as flow; plotted together with density and void results, they help engineers choose the binder content for a road mix.

On this machine the operator sets the loading rate your test method specifies within the 6–60 mm/min range, starts the test and watches the load curve build on screen, while the unit stores each result for later reporting. The hand wheel allows slow manual movement when the load system is being calibrated. Keep the platens clean of bitumen, check the limit switches before each session and run the frame on a firm, level bench.

What to Specify When Ordering

• The test method and specimen size you work to, so that accessories can be confirmed in the quotation
• The loading rate or rates you need within 6–60 mm/min
• The sensors you intend to connect, such as load cells or displacement transducers
• The electrical supply available at your laboratory

Core Drilling Machine (Petrol) (Product Code: SLE/CE/82) is a wheel-mounted pavement core drill used to cut cores up to 200 mm diameter from concrete, asphalt and similar hard construction materials. Road and building testing teams use it where mains power is not at hand, because it runs on a 6.5 HP four-stroke petrol engine (190 cc) with drill speeds of 900 and 350 rpm. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Petrol Core Drilling Machine Used For?

Cores drilled from hardened concrete and bituminous pavements let engineers check what was actually built: layer thickness, compaction, density and, after trimming, compressive strength in the laboratory. The drill head runs down the column under ball-screw control, so the operator can apply steady pressure through the cut and then return the head quickly. Water fed through the built-in swivel cools the diamond bit and flushes out cuttings.

Choose 900 rpm for softer layers such as asphalt and 350 rpm for hard concrete. Level and fix the wheeled base before starting, keep the water flowing throughout the cut, and wear eye and hearing protection around the running engine. For civil engineering departments buying engineering lab equipment in India, a petrol core drill also gives students real field-sampling practice.

Centrifuge Extractor – Motorised (Product Code: SLE/CE/83) is an electrically driven centrifuge used to wash bitumen out of bituminous paving mix samples with a solvent, so that binder content can be determined in highway and civil engineering laboratories. It takes samples of up to 1500 g and runs at 2,400 to 3,600 rpm, with a dimmer stat for speed control. It is made at its own Ambala factory by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM engineering lab equipment manufacturer in India.

Specifications

What Is the Motorised Centrifuge Extractor Used For?

Checking how much bitumen a mix really contains is a routine quality test on road projects. A weighed sample of loose mix is placed in the extractor bowl and soaked in solvent until the binder dissolves; the bowl is then spun so the solvent carrying the bitumen is thrown out and drained away. Washing and spinning are repeated until the solvent runs clear, and the dried aggregate left behind is weighed — the loss in mass gives the binder content.

The recovered aggregate can then be sieved to confirm the grading of the mix. With the dimmer stat, bring the speed up gradually rather than switching straight to full speed, so solvent does not splash. Work in a well-ventilated area, keep the lid secured while the bowl turns and wait for it to stop before opening. Laboratories comparing a laboratory centrifuge in India for bitumen work should match the 1500 g capacity to their usual sample size.

What to Specify When Ordering

• Confirmation that your laboratory supply is 230 V, 50 Hz, single phase AC
• Number of extractors needed for your student batches or daily sample load
• Whether filter papers or rings for the bowl should be quoted — ask us what is included

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597), the OEM that makes this motorised centrifuge extractor. It is produced at the company's licensed factory premises at 449, HSIIDC Industrial Area, Saha, Ambala, which operate under Factory Licence AMB-ONLINE-CHD-J-414.

Highway laboratories, engineering colleges, dealers and importers buy direct from the factory, and requests for spare parts or repeat units go to the manufacturer itself — just ask us. The company profile describes ScienceLab in more detail.

Digital Penetrometer (Product Code: SLE/CE/84) is a microprocessor-controlled bench instrument used to measure how far a test probe penetrates a sample, for example in bitumen penetration testing in highway and materials laboratories. It resolves penetration to 0.01 mm over a 0–50 mm range, moves automatically to the test start point and plots the penetration/time curve on a 6-inch touch screen. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Digital Penetrometer Used For?

Penetration is the depth a loaded probe sinks into a sample in a set time at a controlled temperature, and for paving bitumen it is one of the main grading tests. On a manual penetrometer the operator lowers the needle to the surface, releases it and reads a dial. This instrument automates those steps: it finds the start point, times the penetration and the delay, records the depth to 0.01 mm and draws the penetration/time curve.

The eight programmable holder positions let several points on a sample be tested in sequence, and up to six results can be shown side by side and averaged. Results go to a database via USB, or to a PC over LAN, for reports. Bring samples to the required test temperature before testing, clean the probe between readings and use the LED lamp to check contact with the surface. It suits laboratories adding modern test and measurement instruments in India to their bitumen section.

What to Specify When Ordering

• The test method or methods you follow, so that needles, weights and holders can be confirmed
• Whether sample conditioning equipment should be quoted as well
• Whether you will use the USB database, the LAN link to a PC, or both
• The electrical supply at your laboratory

Centrifuge Extractor Hand Operated (Product Code: SLE/CE/85) is a manually driven bitumen extractor used to determine and check the bitumen percentage in bituminous mixes in road site laboratories and civil engineering teaching labs. A handle turns enclosed gears in its cast body to spin a removable 1500 g aluminium rotor bowl, and solvent can be added mid-test through holes in the housing cap. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM and technical educational equipment manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Hand-Operated Centrifuge Extractor Used For?

Site laboratories near a hot-mix plant often need a quick binder content check where electricity is limited. The operator weighs the loose mix into the aluminium bowl, pours in solvent, fits the cap and tightening nut and turns the handle. The enclosed gears spin the bowl fast, throwing out solvent that carries the dissolved bitumen; it collects in the housing and leaves through the drain.

Fresh solvent is added through the holes in the housing cap while the bowl keeps turning, until the liquid coming out runs clear. The aggregate left in the bowl is then dried and weighed, and the loss in mass gives the bitumen percentage. Tighten the nut firmly before spinning, turn the handle at a steady pace, work in a well-ventilated space and wipe the bowl and housing clean after each test.

Frequently Asked Questions

What does the Centrifuge Extractor Hand Operated determine?
The Centrifuge Extractor Hand Operated (SLE/CE/85) is used to determine and check the bitumen percentage in a bituminous mix. Solvent dissolves the bitumen, centrifugal action removes it from the bowl, and the aggregate left behind is weighed to calculate the binder content.

What is the bowl capacity of the hand-operated extractor?
The Centrifuge Extractor Hand Operated has a removable aluminium rotor bowl with a capacity of 1500 g. A cap and tightening nut hold the sample in place while the bowl spins, and the bowl lifts off the shaft for emptying and cleaning.

How is the bowl of the Centrifuge Extractor Hand Operated turned?
On the Centrifuge Extractor Hand Operated, a handle drives enclosed gears in the cast body, which rotate the vertical shaft and bowl fast. No electrical supply is needed, which makes the extractor convenient for site laboratories.

Can solvent be added while the extractor is running?
Yes. The Centrifuge Extractor Hand Operated has holes in the cap of its housing through which solvent is introduced during the test. A drain collects the dissolved bitumen that is thrown out of the rotating bowl into the housing.

Who manufactures the Centrifuge Extractor Hand Operated?
The Centrifuge Extractor Hand Operated is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory at Saha, Ambala, Haryana, India. Laboratories, dealers and importers in India and international markets can order it direct from the manufacturer.

Should I choose the hand-operated or the motorised centrifuge extractor?
Choose the Centrifuge Extractor Hand Operated where power is unreliable or unavailable, such as at road sites. The motorised model suits laboratories with a steady supply that prefer electrical speed control; ask us to compare the two for your sample load.
