It's important to choose the rightcold trapfor your application.The correct cold trap will efficiently trap solvents for proper disposal or reuse, prevent solvent vapor from getting into your laboratory, and protect your vacuum pump to extend its life span.

Here are some guidelines to help you choose the correct cold trap for your application.

• A-50C cold trapis recommended for aqueous solvents.The recovery rate of aqueous samples using a -50C cold trap is 99.3%.
• A-84C cold trapis better for solvents, such as Acetonitrile, which will recover about 97% of the solvent being evaporated.
• A-105C cold trapis best for alcohols like Methanol, with 94% recovery.

Important: If you'll be using acids, protect your cold trap with a glass insert to prevents acids from attacking the stainless steel.

If you need to get started quickly and don't have the correct cold trap for your process, cold traps can beshipped out in 48 hours or less.
