XtalLight 100

XtalLight 100

Its main application is UV-light illumination of protein samples and excite intrinsic tryptophane fluorescence. In protein crystallography it provides a quick way to distinguish salt from protein crystals on the spot.

UV-Light Source as desktop microscope upgrade

XtalLight 100 can be used in combination with a variety of standard laboratory microscopes to provide additional UV illumination of a sample. The UV light is delivered to the sample via a light guide, bypassing the microscope optics. Different lengths of light guides provide flexibility in the arrangement of the units, allowing installations in confined spaces.

Protein Crystal Identification

One of the most convenient ways to identify the material a crystal is made of is to use intrinsic fluorescence imaging.
