Cryo Jet
Cryostream mount- At 45° about the beam axis (5° towards the source, no distance restrictions)
- Cryostream centered within 0.5 mm around the crystal
- Distance of cryo-nozzle adjustable from 8 mm to 18 mm
Cryostream exhaust
- Adjustable flow rate, up to 50 l/min capacity
- Improved flow conditions around the sample, virtually no icing near the sample
