Vacuum traps are essential elements when working with vacuum or Schlenk lines. These have the primary purpose of preventing flammable, explosive and toxic vapors from entering the vacuum pump. For best results, two traps should be utilized, one to collect bulk solvent and the other strictly to protect the pump. For more about the practical aspects of traps on vacuum and Schlenk lines, be sure to consult the Vacline Page of our Glassware Gallery.
No trap is complete without a Dewar to hold your cyrogen. We offer 1,000 and 4,300 mL Dewars as stock items and can do other sizes and types (even liquid helium) as customer orders.
