Glass Double Maniflod Vacuum Gas Distributor For Schlenk Line With 0-8mm High Vacuum Valve & # 15 O-Ring Joints Air-Free Chemistry Lab Glassware

DESIGN----This is a double-bank manifold for use with vacuum and inert gas with 15# O-ring joints at the end of the banks.One bank is connected to a source of purified inert gas vented through a oil bubbler .The other is connected to a vacuum pump.With 0-8mm high vacuum valves on the ports allowing vacuum or inert gas to be selected without the need for placing the reaction vessels on a separate line. The ports are fitted with 15# O-ring joints. USE------Vacuum/gas manifold is the key component of the schlenk line which is a commonly chemistry apparatus used to manipulate moisture-and air-sensitive compounds with vacuum and inert gas in organic, inorganic and bioorganic chemistry.In a schlenk line, a gas bubber is attached to the outlet end of the inert gas line,a cold trap is placed in between the manifold and the vacuum trap.The reaction lines are attached to reaction flasks or tubes via heavy-wall rubber tubing. DIMENSIONS----This double vacuum gas manifold is designed with 0-8mm hi
