Centrifuge Extractor Hand Operated
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
| Parameter | Detail |
|---|---|
| Purpose | Determination and checking of bitumen percentage in bituminous mix |
| Principle | Mix is treated with solvent and the dissolved bitumen is removed by centrifugal action |
| Drive | Hand operated; a handle turns enclosed gears in the cast body to rotate the shaft and bowl fast |
| Bowl | Removable aluminium rotor bowl, capacity 1500 g, with cap and tightening nut |
| Mounting | Bowl assembly on a vertical shaft protruding from a cast housing |
| Solvent addition | Through holes in the cap of the housing, during the test |
| Drain | Collects the dissolved bitumen thrown from the rotating bowl into the housing |
| Power | Manual — no electrical supply needed |
| Product code | SLE/CE/85 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
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.
OEM Manufacturer
The hand-operated centrifuge extractor is made by Jain Scientific Equipments Private Limited, known by its trading name ScienceLab, as the original equipment manufacturer. It is produced at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied directly to highway site laboratories, engineering colleges, dealers and importers.
Replacement bowls, caps and nuts can be requested from the manufacturer itself — ask us about availability when you enquire. The ScienceLab profile explains more about the company.

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.
