60mL Cooling Funnel All-Inclusive High Vacuum Valve Section Door SCHLENK LH-55-F-03, 24x19, LH Labware

LH-55-F cooling funnel (all-inclusive high vacuum valve section door) SCHLENK

Used to prepare block copolymer synthesis under high vacuum conditions. The design of the cooling funnel is sealed with a large diameter tube as a cooling chamber and an addition funnel to reduce pressure and can be widely used in the cooling chamber in a wide range of dry ice and liquid nitrogen. 
         The opening of the cooling chamber is designed to facilitate the addition of coolant, especially dry ice. The 0~4mm all-inclusive high vacuum valve is used as the connection between the pressure balance arm and the lower inner tube. By positioning the valve, the material in the addition funnel is allowed to remain in an inert environment. 
         The upper right end of the cooling chamber is a 14# grinding port. A grinding plug of LH-298 and LH-298-S can be added at the grinding point, and the sample is taken by a syringe. There is a draft tube behind the cooling chamber of the cooling funnel. 
         The high-vacuum valve of the all-inclusive ring is corrosion-resistant and has a high vacuum.
