Manometer/Bubble, Double

This double mercury manometer/bubbler is a useful accessory for vacuum/inert systems. It can be used for Schlenk manipulations, transfer of approximate quantities of gases, and for measurement of intermediate pressures. The double reservoir design allows a smaller overall volume of mercury to be used for both exhausting the excess inert gas and to fill the tube on the vacuum side. Both sides may be evacuated to ensure an oxygen-free environment. The top has a bump trap to prevent mercury from contaminating the system. Hose connections have an 11mm OD at the largest serration. Overall dimensions are 120mm W x 1200mm H. PLEASE NOTE: NOT SUPPLIED WITH MERCURY.
