What Is the Rubber Cone Used For?
In suction filtration a Buchner or Hirsch funnel stands in the neck of a filter flask whose side arm is connected to a water-jet or vacuum pump. A rubber cone between the funnel and the flask neck seats the funnel firmly and lets the suction seal, so the solid stays on the filter paper while the filtrate collects in the flask. Chemistry practicals in schools and colleges use this set-up to collect crystals and precipitates quickly, and research labs use it for routine filtration. Natural rubber grips glass and porcelain well; keep the cone away from oils and organic solvents, which make it swell, and from heat beyond the listed limit.
What to Specify When Ordering
- Size — the neck size of your filter flask and the funnel the cone must hold.
- Quantity — the minimum order is 10 units; plan one per filtration set-up plus spares.
- Matching items — filter flasks, Buchner funnels and pressure tubing can go on the same enquiry.
Frequently Asked Questions
What does a rubber cone do in filtration?
It sits between the funnel and the neck of the filtration flask, giving the set-up stability and a rubber seal so that suction draws the liquid through the filter.
Which sizes are available?
The listing does not give sizes. Send the flask neck size and the funnel you use, and JLab will confirm a matching cone in the quotation.
How does it differ from JLab’s filter adapter sets?
The adapter sets are graded sets — seven neoprene cones in one, eight rubberised adapters that nest in the other — for labs that use several funnel sizes. This listing is a single natural rubber cone at shore hardness 45.
Who manufactures the rubber cone?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, and quotes for it as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a laboratory equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. Its filtration accessories are produced at JLab’s own works, not sourced from a trader, so schools, colleges, dealers and importers order factory-direct, every cone is checked by eye before packing, and repeat orders are handled by the maker. JLab exports worldwide and ships to buyers in every region — for example Sweden in Northern Europe, Mauritius in East Africa, the Netherlands in Western Europe, Botswana in Southern Africa and Malta in Southern Europe. Tender information is on the JLab lab tenders page.
