Vacuum short-path distillation kit

2021-4-21 · The short-path distillation kit has many connections, and many clips are used to solve the problem of connecting the various components. If it is just a simple connection, there will be a gap at the glass interface, which will affect the vacuum of the entire device during use. So we need to apply vacuum oil at the interface to fill these gaps
