What Is the Buchner Flask Used For?
A Buchner flask is the receiving vessel in suction filtration. A Buchner funnel lined with filter paper sits in the neck on a rubber adapter or bung, the side arm is joined by thick tubing to a water or electric vacuum pump, and the reduced pressure pulls the liquid through far faster than gravity filtration. Students use it to collect and wash crystals after recrystallisation and to separate precipitates in class 11 and 12 chemistry and in college organic chemistry labs, and it is standard chemistry lab glassware in research and quality-control labs.
Before applying vacuum, check the flask for cracks, chips and deep scratches, clamp it so it cannot tip, and fit a trap bottle between the flask and the pump. Never heat a flask under vacuum. When using a water pump, release the vacuum at the flask before turning the tap off so that water is not sucked back into the filtrate.
What to Specify When Ordering
- Size — 250, 500 or 1000 ml, with the quantity of each.
- Glass type — the listing says glass; ask JLab to confirm the glass type with your quote, or choose the borosilicate filter flasks above.

Frequently Asked Questions
What is a Buchner flask used for?
Vacuum (suction) filtration. With a Buchner funnel in the neck and a vacuum pump on the side arm, it filters precipitates and crystals much faster than an ordinary funnel.
Which sizes are available?
Three sizes are listed: 250, 500 and 1000 ml. For 100 or 2000 ml, see the heavy-wall borosilicate filter flasks.
Is the Buchner funnel included?
No. This listing is for the flask only. The porcelain Buchner funnel, the rubber filter adapters, filter paper and a filtering kit with vacuum pump are separate items, linked below.
Is it borosilicate glass?
The listing describes it as glass without naming the type. Ask JLab to confirm the glass with your quotation if your specification calls for borosilicate.
What should an export enquiry include?
Sizes and quantities, the destination country and port or city, preferred delivery terms such as FOB or CIF, any packing or labelling instructions, and the tender reference if relevant.
Who manufactures it?
Jain Laboratory Instruments Pvt Ltd (JLab), at its works in Ambala, Haryana, India; the quotation comes straight from the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a laboratory glassware and science equipment manufacturer in India, incorporated in 2017, with its base on Hargolal Road, Ambala, Haryana. The Buchner flask is produced at JLab’s own works instead of being bought from a trader, so schools, colleges, dealers and importers buy from the maker, every flask gets a visual check before dispatch, and repeat orders are handled by the same team. JLab exports worldwide and ships to buyers in every region — for instance Qatar in the Middle East, Zimbabwe in East Africa, Malaysia in Southeast Asia, Latvia in Northern Europe and Sierra Leone in West Africa. For tender supplies, see the JLab lab tenders page.
