KRYOFLEX II - Low Temperature Device

The KRYOFLEX II is fully integrated with the D8 QUEST and the D8 VENTURE. Our newly developed support mounts from the ceiling of the enclosure to avoid any restriction of the 2-theta range. The transfer line and cables are directed through the labyrinth of the radiation safety enclosure to maintain 100% X-ray safety. The KROFLEX II is also available for the CCD-based solutions in chemical crystallography or structural biology. With the automatic refill from the local 60 liter Dewar it can be run at low temperature uninterrupted for weeks. Ice formation at the sample is avoided by shielding the cold gas stream with dry gas at ambient temperature.

Features include

  • Lowest possible temperature but with reduced liquid nitrogen consumption, by moving the compact heat exchanger near the sample, to achieve a temperature range 90 deg. K to 300 deg. K with liquid nitrogen consumption below 0.5 liters per hour at lowest gas flow rate
  • Running at low temperature uninterrupted for weeks using automatic refill of the local 60 liter Dewar from external nitrogen tank
  • Shielding the cold gas stream with dry gas at ambient temperature, to avoid ice formation at the sample
  • Variable or repeated temperature scans to study phase transitions and other physical phenomena
  • Flexible insulated stainless steel line to transfer liquid nitrogen to a heat exchanger
  • ± 0.1 degree K at 100 K
