双排管真空分配器为带球腔的三通空心玻璃节门.在节门的后部有一个中空的球形玻璃腔,当真空抽气时,球腔内会产生负压,从而使节门塞吸到节门肚上,以提高密封性,节门塞内为平行的双排导气孔,当节门旋转180度时可切换通气或真空.两个主管为22mm(外径).每组节门间的距离为75mm.为保证真空度,每组节门都经过手工精密对研.
● 材质:高硼硅玻璃
● 颜色:透明
● 宽度:300mm、375mm、450mm
● 节门组数:3、4、5
● 空心节门塞的靠尾部真空气囊形成真空,把塞子吸住,真空度高,使用时注意后排抽真空,否则塞子会弹出
● V3941-H375mm 主管道带4个15#法兰接口,可与S3978-01 法兰盘塞子和带15#法兰的抽气小咀配套使用,并需配R3508-09 O型橡胶圈

All glass manifolds are equipped with 4mm double oblique,high vacuum hollow glass stopcocks,which are precision ground with corresponding numbers on barrel and plug.Lower vacuum chambers on the stopcock are evacuated with a separate hole in the plug to secure the plug in the stopcock barrels.Beams have an O.D. of 22mm,and are available in a variety of opening configurations.Distance between stopcocks is 100mm center to center.
● Material:Borosilicate glass
● Color:Clear
● No. of Ports:3、4、5
● Width:11.81 in.(300mm)、14.76 in.(375mm)、17.72 in.(450mm)
● Hollow glass stopcock by vacuum balloon creates a vacuum to suck the plug,high vacuum,note that when using the rear vacuum,otherwise it will pop up stopper
● V3941-H375mm Manifold with #15 O-Ring Joints,Can used with S3978-01 Stopper with #15 O-Ring Joint and hose Connections with #15 O-Ring Joints,R3508-09 Replacement O-rings
