Cold Trap Bath LB-11CTB – Low-Temperature Vapor Condensation Equipment

Cold Trap Bath LB-11CTB is a laboratory system that condenses and captures solvent vapors at −40 °C to −100 °C, protecting vacuum pumps and enabling efficient solvent recovery during evaporation, freeze-drying, and distillation processes.

What Is a Cold Trap Bath LB-11CTB?

Cold Trap Bath LB-11CTB is a low-temperature vapor condensation system designed to trap solvent vapors before they reach vacuum pumps. It improves system efficiency, prevents contamination, and supports solvent recovery in laboratory and industrial applications.

Why Is Cold Trap Bath LB-11CTB Used?

It is used to:

• Protect vacuum pumps from vapor damage

• Recover solvents for reuse

• Maintain clean vacuum conditions

• Improve efficiency of evaporation and drying systems

How Does Cold Trap Bath LB-11CTB Work?

Cold Trap Bath LB-11CTB system cools a trap chamber using refrigeration. Vapors entering the chamber lose energy, condense, and collect before reaching the vacuum pump.

Key Steps:

1. Vapor enters cold zone

2. Temperature drops rapidly

3. Vapor condenses into liquid/solid

4. Collected safely in trap

Key Benefits
