Function of stainless steel condenser tube:



The straight stainless steel condenser tube is generally used in the boiling point determination and distillation operation of liquid organic compounds with boiling point lower than 140 ℃; the distillation of organic compounds with boiling point greater than 140 ℃ can be distilled with air condenser tube.



Spherical stainless steel condensing tubes are usually used for reflux reaction, that is, organic compounds combined with organic compounds. The commonly used condensing tubes are straight condensing tubes, spherical condensing tubes, serpentine condensing tubes, air condensing tubes and spiny fractionating columns.

Spherical stainless steel condenser tube is generally used in reflux reaction, i.e. organic compound synthesis device (due to its large condensation area, good condensation effect); when the boiling point of liquid is very low, serpentine condenser tube can be used. The spiny fractionation column is used in distillation operation, that is, in the separation operation of liquid mixture with little difference in boiling point.
