What Is a Woulff Bottle Used For?
In vacuum (suction) filtration, a pump lowers the pressure inside the suction flask so that the liquid is drawn quickly through the filter paper in a Buchner funnel. If the flask overfills or the filtrate froths, liquid can be carried along the vacuum line, and liquid that reaches an electric pump can damage it. A Woulff bottle placed between the flask and the pump catches that overflow first. That is why it belongs in suction filtration set-ups in college and research chemistry labs, and in senior school practicals that use a vacuum pump.
What to Specify When Ordering

Frequently Asked Questions
Where does a Woulff bottle go in a vacuum filtration set-up?
Between the suction flask and the vacuum source, so that anything drawn out of the flask reaches the bottle before it can reach the pump.
Why fit a Woulff bottle when using an electric vacuum pump?
It prevents filtrate from overflowing into the pump, giving easy protection to an electrical vacuum pump during routine filtrations.
What information is needed for an export quotation?
The quantity, the destination country and port or city, your preferred delivery terms (for example FOB or CIF), any packing or labelling needs, and the tender reference if the order is for a tender.
Who manufactures this Woulff bottle?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of laboratory supplies and chemistry lab equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The bottle is made at JLab’s own works instead of being bought from a trader, so schools, colleges, dealers and importers buy from the manufacturer itself, and repeat orders come from the same source. JLab exports worldwide and ships to buyers in every region — for example Slovakia in Eastern Europe, Belize in Central America and the Caribbean, Burkina Faso in West Africa, New Zealand in Oceania and Chad in Central Africa. Tender buyers can refer to the JLab lab tenders page.
