Oxford Instruments Kelvinox Dilution Insert DIL2

DIL2 was aquired in 2006, mainly financed by the "SNF Förderungsprofessur Michel Kenzelmann". It is equipped with a weak link, allowing access to the range 1...2 K without removing the mixture.

Problems with DIL2

  • The weak link is too weak. For the first experiments we will use a simple copper sample holder, and use the sensor on the mixing chamber.
