Cold traps with Dewar flask

Cold traps with Dewar flasks are made from 3.3 DIN/ISO 3585 borosilicate glass to hold LN2 for vacuum applications. The flasks are vacuum insulated and silver-plated. They are encased in metal sheet, blue coated for protection and have a plastic ring collar, into which the cold trap is inserted. Thus no additional support is needed for the cold trap.
The Dewar flask has got a theoretical coolant capacity of 1.0L or 2.0L respectively.
The cold trap has got a theoretical condensate capacity of 150ml or 250ml respectively.
