Dual flow nitrogen and helium gas cooler for X-ray structure analysis
Technologie, stroje, přístroje a elektronika -> Technologie, stroje a přístroje
The subject matter of this public contract is supply (acquisition) of a dual flow nitrogen and helium gas cooler for X-ray structure analysis. The apparatus must be new, fully operational and complete and it will be used for cooling X-ray samples with a stream of He gas supplied from a cylinder, i.e. without need of liquid helium, and with a stream of nitrogen gas supplied from a lab nitrogen supply. It must seamlessly switch between the helium and nitrogen supply to cover economically the whole temperature range, which must be at least 30-400 K. The cryostat generating the cold flow and the nozzle used for cooling of the crystal sample must be separated, with a connection hose minimally 1-meter long, in order to keep the cryostat out of the diffractometer cabinet.
