Why a Heavy-Wall Filtering Flask with Glass Connector
Vacuum filtration puts a filtering flask under sustained negative pressure, so wall thickness matters more here than on a standard flask — a heavy-wall build resists implosion risk under repeated vacuum cycles. The glass side connector gives a permanent, chemically inert fitting for the vacuum tubing, avoiding the wear that a rubber side-arm adaptor can develop over time, while the white enamel graduation lets the filtrate volume be read directly without a separate measuring step.
Frequently Asked Questions
Why does this flask need a heavy wall?
Filtering flasks operate under vacuum, so a heavy wall gives the strength needed to withstand the negative pressure safely and repeatedly.
What is the glass connector used for?
The glass connector is a side-arm fitting used to attach the vacuum line (via tubing) to draw filtrate through the funnel and filter paper into the flask.
What capacities are available?
This flask is available from 25ml up to 4000ml, each with its own sub-division and graduation range, as listed in the specification table.
Do you export the Flask Filter with Glass Connector outside India?
Yes, this flask is exported to institutional and distributor buyers outside India, with recent enquiries from Sri Lanka, Bangladesh and Nepal among other South Asian markets.
