Heavy-Duty Filtering Flasks Easily Connect to a Vacuum Source
Glass Filtering Flasks are constructed with heavy-duty walls and are designed to take 1 atmosphere of vacuum or 29" of Hg. Filter Flasks feature handy side tubulation. Sizes 125–500mL accept 5⁄16" I.D. flexible tubing. Sizes 1000mL and larger accept 3⁄8" I.D. tubing. Designed to ASTM Specification E1406, Type II, Class 1 requirements.
Filter Flasks with Quick-Release Connector have a quick-release connector designed as a safety feature to accommodate standard 1⁄4" I.D. tubing. Tubing can remain permanently attached because the opposite end is designed to be assembled via a positive threaded seal. Proper positioning of the Hose Connector provides greater flask stability as tubing angled downward has less tendency to tilt the flask.
