  • 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 all opens open.It is designed with 4 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 450mm.
  • 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.

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.
The double or dual manifold is designed with two banks .The two banks are used as a inert gas line and a vacuum line.The inert gas line is attached to an inert gas supply and to the gas outlet by flexible rubber or plastic tubing.The inert gas is usually led to the manifold directly or pass through a drying tube first.and exists from the manifold through a mercury or mineral oil bubbler.The vacuum line is usually closed at one end and attached a vacuum pump at the other.In between the manifold and the pump there should be a cold trap to prevent the solvent vapors from contaminating the vacuum pump.
There are multiple ports with special stopcocks or PTFE high vacuum valves allowing vacuum or inert gas to be selected without the need for placing the reaction vessels on a separate line. For example, gases can be vacuum transferred from one reaction flask to another or several reactions may be run at the same time.The thick-walled rubber tubing is used to lead from the ports to various reaction apparatus.
