Laboy Glass Double Maniflod Vacuum Gas Distributor For Schlenk Line With 4mm High Vacuum Stopcock & # 15 O-Ring Joints Air-free Chemistry Lab Glassware
Special Price $383.30 Regular Price $593.22
- 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 4mm double oblique,high vacuum hollow glass stopcocks on the ports allows vacuum or inert gas to be selected without the need for placing the reaction vessels on a separate line. The ports are fitted with standard taper 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 4mm double oblique,high vacuum hollow glass stopcocks precision ground with corresponding numbers on barrel and plug.Both inert gas and vaccum banks are made from 22mm medium wall tubing with 15# O-ring joint at all ends.It is designed with 4 ports which are spaced 100mm center to center and fitted with two 14/20 and two 24/40 inner joints.
- 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 hollow stopcocks 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 This double vacuum gas manifold is designed with 4mm double oblique,high vacuum hollow glass stopcocks precision ground with corresponding numbers on barrel and plug.Lower vacuum chambers on stopcock are evacuated with a separate hole in the plug in order to hold the plug in the stopcock barrels With 15# O-ring joints instead of the serrated hose connection at the ends of inert gas manifold bank and vacuum manifold bank.The four ports of the manifold are fitted with two 14/20 and two 24/40 inner joints.15# O-ring joint stopper and #15 O-ring joint to serrated hose adapter to be ordered separately.
