Kimble 27070 KIMAX Heavy Wall Graduated Filtering Flasks with Quick-Release Hose Connector. The quick-release connector is designed as a safety feature. Made with a heavier wall than a standard Erlenmeyer flask. Flasks are designed for vacuum to 29” of mercury. Hose barb accommodates 1/4" ID tubing. Tubing can remain permanently attached since the opposite end is designed to be easily assembled via a positive threaded seal. Proper positioning of the connector provides greater flask stability, as tubing angled downward has less tendency to tilt the flask.
