Dewar glass vacuum cold trap for distillation of volatiles. Vacuum trap is required to prevent contamination of your vacuum pump. Cold trap condenses vapors to liquid and extended cold finger keep the liquid cold. Double wall high efficiency design.
Read more...The double dewar trap with extended cold finger is especially suited for immersion chillers. The extended cold finger goes down into the receiving flask which cools the condensed liquids so that it doesn't warm back up and offgas back into the pump. Most people that have dry ice put some in a little bowl under the receiving flask but with our trap design dry ice is not needed. It is also double walled so the vapor hits the first wall and has to travel all the way down, then back up to the top before exiting. This large dewar style vacuum trap is great for collecting large amounts of solvent or volatile compounds.
A vacuum trap or "cold trap" is used to prevent vapors from entering your vacuum pump and contaminating your vacuum pump oil. If your vacuum pump ingests vapor it can be detrimental to performance and longevity of the pump. It is crucial to protect your vacuum pump in order to reach and maintain the required vacuum level, and prevent costly and unnecessary oil changes. Use a refrigerated immersion cooler for use without dry ice.
