1.不銹鋼U型管化學上是干燥裝置，物理上是連通器。
1. Stainless steel U-tube is chemically a drying device and physically a connector.
2.不銹鋼U型管可以用于干燥氣體和收集低沸點液體。在不銹鋼U型管中裝入干燥劑，可以對通過氣體進行干燥，另外，在不銹鋼U型管中裝入白色的無水CuSO4粉末，可以對通過的氣體進行檢驗是否有水的操作，無水硫酸銅不穩定，易吸水，而形成穩定的五水合硫酸銅CuSO4·5H2O，呈藍色，通過顏色變化可以證明氣體含有水蒸氣，該反應迅速靈敏。
2. Stainless steel U-tube can be used to dry gas and collect low boiling liquid. Additionally, white anhydrous CuSO4 powder can be filled in stainless steel U-tube to check whether there is water or not. Anhydrous copper sulphate is unstable and easy to absorb water, thus forming stable pentahydrate copper sulphate CuSO4.5H2O, which is blue. Color, through the color change can prove that the gas contains water vapor, the reaction is rapid and sensitive.文章來源：http://www.turkseksshop.com/
