Capable of 3 ways of usage: 1. Storage under vacuum with a small amount of indicator. Have confidence in dryness according to the indicator color and the built-in vacuum gauge, and know when to quickly recharge the vacuum (Once a month or so). Suitable for solids and high-boiling oils.
2.Storage under inert gas with a small amount of indicator. Very effective but will need to refill with inert gas every time it is opened. Vacuum pump preferred for assistance in the filling. Dual inlet/outlet makes the filling easier.
3.Storage under regular atmosphere with a large amount of desiccant (indicator). The most classic way of usage. To save on consumption, the desiccant should be dried and regenerated once it turns color. The provided dish can be directly heated in an oven so there’s no need of pouring the solids.
Vacuum drop over a period of 1 month: 9%
Desiccant and indicator dish included. Glass dish can be heated directly in oven for best convenience.
