How to Compare the Quality of Vacuum Drying Box

A good vacuum drying chamber can greatly reduce the boiling point of the liquid to be expelled in vacuum environment, so the vacuum drying chamber can be easily applied to heat sensitive substances, and the vacuum drying chamber can effectively shorten the drying time of some powder or other granular samples which are not easy to dry. In terms of temperature, we have to say heat preservation and sealing. At present, most drying boxes are mainly made of fibre cotton, and a few of them are made of polyurethane. In terms of heat preservation effect, polyurethane has better heat resistance and insulation effect than fibre cotton. Generally, polyurethane can keep the high temperature inside the box stable for several hours. It is worth mentioning that polyurethane has high thermal insulation performance, which can effectively prevent the operator from being scalded by excessive temperature outside the box. When the drying box made of fibre cotton is in high temperature, it can only keep the
