KRYO-FLEX LOW TEMPERATURE ATTACHMENT

The KRYO-FLEX Low Temperature Attachment permits crystallographic studies at controlled temperatures by enveloping a crystal sample in low temperature nitrogen gas. The low temperature attachment addresses the need to handle delicate samples and to obtain more accurate structures from small molecules and biological macromolecules.

The KRYO-FIEX features highly stable temperature control with greatly reduced liquid nitrogen consumption. It can be run at low temperature uninterrupted for weeks because of the automafic refill of the local 60 liter Dewar. Ice formation is avoided at the sample by shielding the cold gas stream with gas at ambient temperature.

The KRYO-FIEX features a long 3000 mm flexible insulated stainless steel transfer line allowing it to be mounted easily on different instruments having sealed tube or rotating anode generator enclosures and in synchrotron hutches.

A digital temperature controller and GUI software interface makes it easy to set or change the sample temperature.

Bruker AXS ceramic tubes are 100% compatible with the traditional glass tubes for X-ray diffraction.The main benefit of ceramic insulation versus glass insulation is the higher reproducibility of the focal spot position. This facilitates the change of tubes in case of tube replacement or change of wavelength.The improved design of the cathode leads to a longer life compared to conventional glass tubes.The design of the ceramic tubes guarantees state-of-the-art spectral purity.There are two and four window versions available. The standard version is the two window version. lt provides one line and one spot focus and works with the one window tube housings (type S and type P). The four window version is required for three and four window tube housings in double goniometers, goniometers with film camera, and X-ray work benches.A wide variety of anode materials and focus dimensions are available.When disposing of your used tubes: there is a refund toward the purchase of a new tube from Bruker AXS if a used ceramic tube is returned. Like all Bruker AXS products, the ceramic tubes are manufactured according to ISO 9001standards.
