Cold traps complete KF 29 / KFL 29

Application

  • Gas purification by condensation, e.g. in vacuum systems

Advantages

  • made of borosilicate glass3.3
  • High chemical resistance
  • High thermal resistance
  • Simple, cost-effective design
  • Quick change possible

Executions

  • K = spherical ground joint S29
  • OK = spherical ground joint S29 with O-ring seal
  • GL= Glass thread with olive GL18
  • NW= Vacuum flange
  • Special dimensions
  • Special connections

Simple cold traps, also known as cold fingers, are for standard applications in conjunction with vacuum pumps. Moisture or solvents are condensed out in the chemical application area. The cold trap is used to protect the vacuum pump. The special feature of this design is that the user does not need a tripod to hold the cold trap. The cold trap has a bead with which it is hooked into the support ring of the Dewar flask. The cold trap can therefore be changed quickly and easily. LN2 or CO2 is used for cooling. The coolant should be at least 50°C colder than the condensation temperature of the substance.
