产品特点
用于反应体系的惰性气体保护,一个管为真空抽气管,另一个管为惰性气体加入管,两个管以三通节门相连,
从而控制真空和气体依次进入需保护的瓶中。双排管有不同的规格,可同时进行多组保护反应。
该双排管配有 0-4mm 高真空节门。两个管均采用外径为 22mm 的中等壁厚玻璃管吹制而成,
并带有四个小咀。每个出气小咀的外径为 10mm, 每组高真空节门之间的间距为 100mm。
提示:其中后端真空管的两端分别接入真空泵和真空表。
如用油泵,需在真空管油泵间接入冷阱和杜瓦瓶。其中前端惰性气体管的两端分别接入气体钢瓶和鼓泡器

Product features
For inert gas protection of the reaction system, one pipe is a vacuum extraction pipe and the other pipe is an inert gas inlet pipe. The two pipes are connected by a three-way valve,
Thereby controlling the vacuum and gas to enter the bottle to be protected in turn. The double row tubes have different specifications and can carry out multiple groups of protection reactions at the same time.
The double row pipe is equipped with 0-4mm high vacuum throttle. Both tubes are blown from a medium wall thickness glass tube with an outer diameter of 22 mm,
And has four small nozzles. The outer diameter of each air outlet nozzle is 10mm, and the spacing between each group of high vacuum valves is 100mm.
Note: the two ends of the rear vacuum pipe are connected to the vacuum pump and the vacuum meter respectively.
If the oil pump is used, the cold trap and Dewar bottle shall be connected between the vacuum tube and the oil pump. The two ends of the front-end inert gas pipe are respectively connected to the gas cylinder and the bubbler
