1000 ml filtering filter vacuum flask pyrex no. 5340
Pyrex No. 5340 This filter flask condition is like new. Perfect condition.
This Pyrex brand 1000ml filter flask features tubulations for easy connections to filter pumps. Heavy walls, graduated on sides, flat bottoms. Necks finished to give excellent fitting for rubber stoppers. Ido have rubber stopper if you need one for an extra 5 dollars.
The filter flask looks like an Erlenmeyer flask with a short arm coming out of it. The "arm" is designed to connect the flask to a vacuum source. When sealed on the top with a stopper or a Buchner funnel, the vacuum flask will hold a reduced pressure. Note the heavy walls of this flask - they are designed to withstand reduced pressure without imploding.
Filter flasks are also called "side-arm flasks" and "vacuum flasks" and are used either for filtering solutions or for removing solvent under reduced pressure.
