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 1.0 l or 2.0 l respectively. The cold trap has got a theoretical condensate capacity of 150 ml or 250 ml 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 10 mm O 29 = spherical joints S29 with O-ring seal The standard assembly is designed for use with LN 2 as coolant. When using CO 2 and acetone please order CO 2 grid separately (Dewar Type 12 C Cat. No. 9.032 081 and Dewar Type 18 C Cat.
