DRY ICE 3K OPTI
The DRY ICE 3K OPTI allows up to 5 optical windows and temperatures below 3K.
Cooling of the sample is achieved using a mechanical refrigerator that requires no liquid cryogens. Using a choice of either a Gifford-McMahon or Pulse Tube cold head along with anti-vibration options, we can design a system suitable to the requirements of your experiment.
