Mixer Theoretical Density Meter (Product Code: SLE/CE/86) is a vacuum apparatus used to determine the theoretical density of asphalt mix in highway and civil engineering laboratories. It tests 2 samples at a time in acrylic vacuum containers over a 0–100 kPa (0–750 mm Hg) vacuum range, while a vibratory table with manual and automatic modes helps release entrapped air. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a laboratory instruments supplier in India.

Specifications

What Is the Theoretical Density Meter Used For?

Theoretical density is the density an asphalt mix would have with no air voids at all. Comparing it with the bulk density of compacted specimens or cores gives the air void content, or porosity, and shows how well a pavement layer has been compacted. It is therefore needed both when a mix is designed and when finished road layers are checked.

Loose mix is placed in the acrylic containers, the vessels are sealed and vacuum is applied while the vibratory table agitates them, so that air trapped between the coated particles escapes; the transparent containers let the operator watch it happen. Check that the gauge reads zero before each run, keep the load on the table within 10 kg, and clean the acrylic vessels with a soft cloth rather than abrasives. Testing two samples together speeds up duplicate determinations.

What to Specify When Ordering

• Whether a vacuum pump or other vacuum source should be quoted with the apparatus
• The test method you follow, so that container and accessory details can be confirmed
• Confirmation that your supply is 230 V AC, single phase, 50 Hz
• Number of units needed (each tests 2 samples at a time)

Travelling Beam Device (Product Code: SLE/CE/87) is a wheeled 3 m profile beam used to detect surface irregularity of concrete and asphalt road pavements in construction checks and highway engineering practicals. A middle wheel measures vertical deviation from the line between the two end wheels, up to ±25 mm, and a recording unit draws a graph of the deviations. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM supplying engineering educational equipment in India, at its own factory in Ambala.

Specifications

What Is the Travelling Beam Device Used For?

How smoothly a road rides depends on how regular its surface is along the direction of travel. The travelling beam is pushed along a lane: its two end wheels set a 3 m reference line, while the middle wheel rises over bumps and drops into dips. The movement is shown on the scale and traced by the recording unit, so the graph reveals exactly where the surface departs from a true line and by how much.

Because it rolls continuously, the beam surveys a whole length of new pavement in one pass instead of one spot at a time. Use it on freshly laid layers before acceptance, and on existing roads for condition surveys. Keep the wheels clean of bitumen and grit, check the scale reading on a flat reference surface before starting, and move the approx. 55 kg beam with two people.

What to Specify When Ordering

• Number of beams needed for your survey teams or student groups
• Whether spare recording charts or parts for the recording unit should be quoted — ask us
• Whether a 3 m straight edge for spot checks should be included in the same quotation

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, a registered MSME enterprise (Udyam UDYAM-HR-01-0003714) whose major activity is manufacturing. The company is the OEM of this travelling beam device, which is produced at its own licensed factory at Saha, Ambala, Haryana, India.

Highway departments, engineering colleges, dealers and importers are supplied factory-direct, and export consignments are handled under Importer-Exporter Code AAECJ8618A (DGFT). For replacement wheels or recording-unit parts, ask the manufacturer directly. Read more on the ScienceLab profile.

Frequently Asked Questions

What does the Travelling Beam Device measure?
The Travelling Beam Device (SLE/CE/87) detects road surface irregularity by measuring how far the pavement deviates vertically from the straight line between the two end wheels of its 3 m beam. It can be used on both concrete and asphalt pavements.

What measuring range and scale does the travelling beam have?
The Travelling Beam Device measures a maximum vertical deviation of ±25 mm. Its scale is marked in 2 mm increments up to 10 mm and in 5 mm increments from 10 to 25 mm, which suits both small ripples and larger dips.

Does the Travelling Beam Device record its readings?
Yes. The Travelling Beam Device is supplied complete with a recording unit that produces a graph of vertical deviations as the beam moves. The trace gives a continuous record of the surveyed length that can be kept with the site report.

How is the travelling beam different from a 3 m straight edge?
A 3 m straight edge checks the surface at one position at a time, whereas the Travelling Beam Device is rolled along the pavement and records deviations continuously. Many highway laboratories use the straight edge for quick spot checks and the beam for longer runs.

How heavy is the Travelling Beam Device?
The Travelling Beam Device weighs approximately 55 kg. It runs on its own wheels during a survey, but two people should lift it on and off a vehicle, and it should be stored so that the beam and wheels are not knocked out of line.

Who manufactures the Travelling Beam Device?
The Travelling Beam Device is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory at Saha, Ambala, Haryana, India. Quotations come directly from the manufacturer for buyers in India and international markets.

Straight Edge (3 meter) (Product Code: SLE/CE/88) is a lightweight beam approximately 3 m long used to check the lateral surface regularity of roads and pavements on site and in highway engineering practicals. Made of mild steel or aluminium, it rests on supports at both ends that hold it at a set height above the surface, and irregularities are read with incremented wedges. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM and engineering lab equipment manufacturer, at its own factory in Ambala, India.

Key Details

What Is the 3 m Straight Edge Used For?

The straight edge is laid across the road surface on its two end supports, so the beam sits at a known height above a perfectly flat line. Wherever the pavement dips or rises, the gap under the beam changes; sliding an incremented wedge into the gap at that point shows how large the irregularity is. Readings are taken at intervals across the lane to build up a picture of the cross-section, for example where wheel paths have worn or settled.

The method needs no power and very little training, which makes it a practical first exercise in pavement evaluation for students and a quick acceptance check for site engineers. The aluminium version is easier to carry between test points, while mild steel suits heavier handling. Store the beam flat or hung along its length so it does not bend, wipe off bitumen and dust after use, and check it against a flat reference now and then.

What to Specify When Ordering

• Material: mild steel or aluminium
• Number of straight edges needed for your survey teams or student groups
• Whether incremented measuring wedges should be quoted with the beam — ask us what is included

OEM Manufacturer

Jain Scientific Equipments Private Limited trades as ScienceLab and is the original equipment manufacturer of this 3 m straight edge. The beam is made at the company's own licensed factory at Saha, Ambala, Haryana, India, and is supplied factory-direct to highway departments, engineering colleges, polytechnics, dealers and importers.

Ring And Ball Apparatus (Electrical) (Product Code: SLE/CE/89) is an electrically heated test set used to determine the softening point of bitumen and similar binders by the ring and ball method in highway and civil engineering laboratories. Each unit comes with a heat-resistant glass bath, tapered rings, a 9.5 mm steel ball, a ring holder and an electric hot plate with energy regulator. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM and a scientific lab equipment manufacturer in Ambala, India, at its own factory.

Specifications

What Is the Ring and Ball Apparatus Used For?

Bitumen has no sharp melting point; it softens gradually as it warms. The ring and ball test puts a number on this behaviour: molten binder is cast into the tapered rings, a steel ball is placed on each disc, and the assembly in the ring holder is heated in the glass bath. The temperature at which the softened binder lets the ball sink through and reach the base is recorded as the softening point, which is used with penetration to grade paving bitumen.

The energy regulator lets the operator hold a steady, controlled rate of heating, which matters because a faster rise gives a misleading result. Stir the bath liquid gently for an even temperature, keep the balls centred on the discs, and read the temperature on a thermometer placed near the rings. The clear glass bath lets students watch the binder sag, which makes it a clear demonstration piece among engineering lab equipment in India for highway practicals.

What to Specify When Ordering

• Number of sets needed for your laboratory or student batches
• Whether a thermometer should be quoted, and the range your method requires
• Whether spare tapered rings or steel balls should be included — ask us
• Confirmation that your supply is 230 V, 50 Hz, single phase AC

Cut Back Bitumen Distillation Equipment (Product Code: SLE/CE/90) is a distillation set used to separate the volatile fraction of cutback bitumen from its residue, so the distillate can be measured and the residue tested further in highway laboratories. It comprises a heavy-gauge shield with chimney, an electric hot plate with energy regulator, a 500 ml distillation flask and a 100 ml Crow receiver. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM maker of laboratory distillation apparatus in India, at its own factory in Ambala.

Specifications

What Is the Cutback Bitumen Distillation Apparatus Used For?

Cutback bitumen is bitumen thinned with a volatile solvent so it can be sprayed or mixed at lower temperatures; once laid, the solvent evaporates and the binder hardens. The distillation test shows how much volatile material a cutback contains and leaves behind the residue that will remain on the road. A measured sample is heated in the 500 ml flask inside the shield, and the distillate is collected in the 100 ml Crow receiver so that its volume can be read at the stages your method specifies.

The residue left in the flask is then tested for properties such as penetration or softening point. Use the energy regulator to keep the distillation rate steady, and the shield to protect the flask from draughts. Solvent vapours are flammable, so work in a fume cupboard, keep ignition sources away and let the set cool before dismantling. An ASTM 8C thermometer (−2 to +400 °C) must be fitted, as none is supplied.

What to Specify When Ordering

• Whether the specified ASTM 8C thermometer should be quoted, as it is not included
• Spare 500 ml distillation flasks and 100 ml Crow receivers, if required
• Whether a stand, condenser or other fittings should be quoted — ask us what is included
• The electrical supply at your laboratory for the hot plate

Standard penetrometer (Product Code: SLE/CE/91) is a dial-type needle penetration instrument used to measure the consistency of bitumen and similar semi-solid materials in civil engineering and highway materials laboratories. Engineering colleges, polytechnics and road-materials labs use it for penetration tests, reading needle depth on a dial graduated in 400 divisions of 0.1 mm. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer of engineering lab equipment in India, at its own factory in Ambala.

Specifications

What Is the Bitumen Penetrometer Used For?

In a bitumen penetration test, the conditioned sample in its container is placed under the needle and the tip is lowered with the rack-and-pinion adjustment until it just touches the surface. The needle is then released for the time set by the test method, and the dial shows how far it sank in tenths of a millimetre. Harder grades give lower readings, so students and technicians use the result to compare and classify paving bitumen. The 50 g and 100 g ring weights let the operator make up the load the method calls for.

Fitted with the accessory penetration cone, the same stand gives empirical penetration values for lubricating grease and petroleum jelly, which makes it useful lab equipment for technical institutes that teach both highway materials and petroleum products. Level the base with its screws before each series, keep the needle clean and straight, and use the clutch to return the dial to zero.

What to Specify When Ordering

• Number of complete penetrometer stands required for your laboratory
• Whether the penetration cone for grease and petroleum jelly is needed
• Any spare bitumen penetration needles or sample containers beyond the supplied set (ask us)
• Any additional 50 g or 100 g ring weights

OEM Manufacturer

The Standard penetrometer is an OEM product of Jain Scientific Equipments Private Limited, the company that trades as ScienceLab. Its pillar stand, measuring head and fittings are made and assembled at the company's own licensed factory at Saha, Ambala, Haryana, India, rather than bought in from a trader.

Units are supplied factory-direct to engineering colleges, polytechnics, testing laboratories, dealers and importers. For institutional vendor registration, the company's details are GSTIN 06AAECJ8618A1ZT and LEI 3358004HRD1JIVXKYX49.

Kinematic Viscometer Bath (Product Code: SLE/CE/92) is a temperature-controlled glass bath used to hold capillary viscometer tubes while the kinematic viscosity of bitumen, oils and other liquids is measured in materials and petroleum testing laboratories. Civil engineering, chemistry and polytechnic labs choose it for its high-precision digital display, electric stirrer and compact desktop all-in-one design. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Key Details

What Is the Kinematic Viscometer Bath Used For?

Kinematic viscosity is found by timing how long a fixed volume of liquid takes to flow through a calibrated glass capillary viscometer kept at a constant temperature. This bath provides that stable, stirred environment: the viscometer tube is suspended in the glass bath, the sample is allowed to reach bath temperature, and the flow time between the timing marks is multiplied by the tube constant. Highway materials labs use it for bitumen and cutback binders, while chemistry and petroleum courses use it for lubricating oils.

For repeatable readings, let the bath settle with the stirrer running before inserting tubes, keep the glass walls clean so the meniscus stays easy to see, and clean and dry each viscometer tube between samples. As a laboratory instruments supplier in India, we can advise on the tube type your method needs when you enquire.

Aggregate Crushing Value Apparatus (Product Code: SLE/CE/93) is a steel cylinder-and-plunger set used to find how much coarse aggregate breaks down under a gradually applied compressive load in civil engineering and highway materials laboratories. Engineering colleges and testing labs use it with a compression testing machine, and the set is built around a 150 mm diameter mild steel cylinder with a 148 mm plunger. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Aggregate Crushing Value Apparatus Used For?

The aggregate crushing value (ACV) test rates how well road stone and concrete aggregate resist crushing. A graded sample is first measured in the metal measure, filled in layers and tamped with the rounded rod, then transferred to the 150 mm cylinder on its base plate and levelled. The plunger is placed on top and the assembly is loaded steadily in a compression testing machine to the load the test method specifies.

After loading, the crushed sample is sieved and the fines are expressed as a percentage of the original mass; a lower value indicates a stronger aggregate. Because the set is simple and robust, it is common engineering lab equipment in polytechnics and TVET workshops, where students compare aggregates from different quarries. Keep the plunger and cylinder bore clean so the plunger moves freely.

What to Specify When Ordering

• Number of complete sets (cylinder, plunger, base plate, measure and tamping rod)
• Any spare tamping rods or metal measures
• Whether you also need a compression testing machine to apply the load

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, and this Aggregate Crushing Value Apparatus is one of its own OEM products. The cylinder, plunger, base plate and measure are made at the company's licensed factory at Saha, Ambala, Haryana, India, not sourced from a trader.

Because the maker quotes directly, colleges, materials-testing laboratories, dealers and importers get factory-direct supply and can ask the manufacturer itself about repeat orders or replacement parts. Find out more about the company on the ScienceLab profile page.
