YUCHENGTECH Double Bank Vacuum Gas Distributor Glass Manifold Vacuum Gas Chemistry Lab Glassware with Hollow Valves (4-Port)

Note: This is a double bank Vacuum Gas Distributor with 4 Hollow Valves. The appearance and color of all products shall be subject to the real object, and there is color difference in photos. The pictures are for reference only. Parameter : The diameter of Hollow Valve of double bank gas distributor：about 2mm to 4mm The outer diameter of main pipe: 22mm The outer diameter of the right air pouring nozzle ：10mm The distance between each two valve : 100mm Total length :450mm Main application: 1.The vacuum gas distribution pipe is used for the organic synthesis reaction in the laboratory and protects the reactant inert gas. 2.The vacuum gas distribution pipe is matched with thermometers, condensing tubes, stirring rods, separating funnels and other instruments to assemble a component distillation unit, a distillation unit or a reflux device to performed more complicated boiling, fractionation and purification operations . Guarantee： Vacuum gas distribution pipe belongs to glassware and is fragile. We have made shockproof and shatterproof packing, but it may be damaged in the process of transportation.

• 1.【Higher Sealing Performance】▶The Stopcock of Vacuum Gas Distributor is made of Hollow Valves,the Hollow Valves have higher sealing performance .
• 2.【High temperature resistant】▶Borosilicate glass has a very low coefficient of thermal expansion, which is about one third of ordinary glass. It is resistant to high temperature and temperature change of 200 ℃.
• 3.【The material stability】▶Borosilicate glass is a kind of special glass material with low expansion rate, high temperature resistance, high strength, high transparent light rate and high chemical stability.
• 4.【Main application】▶The vacuum gas distribution pipe is mainly used in the laboratory for organic material synthesis reaction, or for more complex boiling, fractionation and purification operations.
• 5.【High transparency】▶The vacuum gas distribution pipe is made of special glass material with high light transmittance, which is convenient and intuitive in operation and has high transparency.
