Rigaku cryogenics for X-ray crystallography
Both macromolecular and small molecule crystallographers employ cryo-cooling of crystals to enhance data quality. This technique requires both a cryogenic nitrogen gas stream to cool crystals during the X-ray exposure and a supply of liquid nitrogen (LN2) in which to flash cool and store crystals. Traditionally, these requirements were fulfilled by maintaining an inventory if LN2 dewars which could be subject to availability problems.
Rigaku offer two products that eliminate the need for crystallographers to have access to a supply of liquid nitrogen. The award winning Rigaku X-stream 2000 low temperature system provides a temperature regulated laminar flow stream of cryogenic nitrogen gas. To supply LN2, Rigaku offers the innovative self-contained NitroGen system.
