| Cold traps with Dewar flask, borosilicate glass 3.3 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. Items supplied: Cold trap, Dewar-flask, plastic ring. Dewar type 12C/18C: see no. 9.032.024 / 9.032.030 Versions Cold trap joints: S29 = spherical joints GL18 = glass screwthead with PTFE olive 10mm O 29 = spherical joints S29 with O-ring seal The standard assembly is designed for use with LN2 as coolant. When using CO2 and acetone please order CO2 grid separately (Dewar Type 12 C Cat. No. 9.032 081 and Dewar Type 18 C Cat. No. 9.032 082).
