Vapor Traps

Vapor traps play a critical role in laboratory safety and efficiency, capturing unwanted vapors before they can contaminate the workspace or damage equipment. These devices, including vacuum traps, glass cold traps, dry ice condensers, and steam traps, are designed to condense or absorb vapors from experiments or vacuum systems. They protect sensitive instruments and maintain a clean air environment, essential for precise scientific work. Vapor traps are available in various designs to suit different types of vapors and laboratory setups, ensuring that labs can maintain the highest standards of safety and cleanliness.
