Description of Laboy Glass Double Maniflod Vacuum Gas Distributor For Schlenk Line With 5-Port High Vacuum Valves Front-Right&Rear-Left Hose 550Mm In Length Air-Free Chemistry Lab Glassware
DESIGN----This is a double-bank manifold for use with vacuum and inert gas.One bank is connected to a source of purified inert gas vented through a oil bubbler .The other bank is connected to a vacuum pump.The 0-4mm high vacuum valves on the ports allows vacuum or inert gas to be selected without the need for placing the reaction flasks or tubes on a separate line.There are hose connects on the vacuum/gas banks and the reaction lines. 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----The high vacuum valves are metered from 0 to 4mm for grease-free operation.Both inert gas and vaccum banks are made from 22mm medium wall tubing and have front-right&rear-left hose open.It is designed with 5 ports which are spaced 100mm center to center and the hose connections have an O.D.of 10mm at the largest serration.The overall width is 550mm. HEAVY WALL ---This vauum gas manifold is heavy-wall designed , made by hand-blowing according to ASTM E438 ,made of high-quality borosilicate glass and annealed at 800 degree Celsius ,can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling,durable and reusable. 100% 90 DAY MONEY BACK GUARANTEE If you are not satisfied for any reason, simply return for a full refund, no questions asked.
