Airfree® Schlenk Graduated Addition Funnels

The funnel?s advanced functionality is built around its dual high-vacuum stopcocks. The T-Bore stopcock on the equalizing arm is a unique feature that allows you to easily purge and isolate the funnel's contents, or even store them without contamination—a crucial step for air-free work. Both the T-Bore and the straight-bore stopcocks are 2 mm high vacuum glass stopcocks with a constant pressure retention device, guaranteeing a leak-tight seal that is essential for maintaining a pristine atmosphere. With the top and bottom joints being the same size, this funnel integrates effortlessly into any modular Schlenk setup, making it an indispensable part of your lab.
