Cold finger S29 / SL29



Applications

  • gas cleaning by condensation e.g in vacuum systems

versions

  • K = spherical joint S29
  • OK = spherical joint S29 with O-ring sealing
  • GL= Glass screwthread with olive GL18
  • NW= Vacuum flange
  • special dimensions
  • special connections

Advantages

  • made of Borosilicatglas 3.3
  • good chemical resistance
  • good thermal resistance
  • simple low cost design
  • quick exchange is possible
Simple cold traps, which are also known as cold finger condensers, are used in standard applications in conjunction with vacuum pumps and the condensation is forced out of the humidity or solvents used in the chemical applications. The cold trap is used to protect the vacuum pump in this case and the speciality of this type of construction is that the user does not need to use a stand to hold the cold trap. The cold trap has a rim, which is hung inside the Dewar-flask's support ring. The cold trap can be changed very quickly without any problems arising. LN2 or CO2 is used for cooling. The coolant should be at least 50 ° C colder than the condensation temperature of the substance
