Filter Flasks

Filter flasks (Kitasato/Büchner flasks) are heavy-wall borosilicate vessels with a side-arm for vacuum filtration. Models are available graduated or ungraduated, with glass hose connectors and standard joint options to pair with stoppers or adapters. The thick walls provide strength under reduced pressure, and clear markings aid volume checks. Suitable for use with Büchner funnels, filter holders, and membranes in microbiology, chemistry, and routine sample preparation.
