Kimble Chase Glass Filter Flask 250 ml Heavy Wall Vacuum Hose Barb

The Kimble Chase 617500-0003 Glass Filter Flask is a specialized laboratory vessel designed for vacuum filtration and the safe handling of filtrate. This flask has a capacity of 250 ml and is constructed from heavy wall borosilicate glass, a material chosen for its excellent chemical resistance and enhanced durability, which is essential for withstanding the vacuum pressure applied during filtration.

A key feature of this flask is the sidearm with a vacuum hose barb. This integral fitting allows for the secure attachment of a vacuum hose, connecting the flask to a vacuum source (like a pump or aspirator). The flask is used as the receiver in a filtration setup, where a filter funnel (such as a Büchner or Hirsch funnel) is placed into the flask's neck. The heavy wall construction provides an added measure of safety against implosion under vacuum.

This Kimble Chase filter flask is a fundamental tool for chemistry and biology laboratories, facilitating the rapid separation of precipitates or solids from liquids.
