Automatic LN2 level control for cold trap applications

To ensure the condensation performance of a cold trap, it is important to maintain a largely constant LN2 liquid level in the Dewar flask. This constant LN2 liquid level ensures that the entire condensate freezing wall of the cold trap is always functional and that the usable volume of the cold trap can therefore be utilized.
Automatic LN2 level control with a glass cold trap type SL29-GL-A, Dewar flask, lid, exhaust pipe and a 25 liter LN2 container. Best. No. 2755-25
