SWISSCI crystallisation plates are available in 3 polymers.  Polystyrene (PS) is a cost-effective polymer that Is optically clear when using standard bright field or visible light sources. However, when imaging drops using both cross polarised (XP) and UV light, the quality of the image is impaired by the interaction of the polymer with the light source.

SWISSCI’s UVP polymer has been designed to reduce the auto-fluorescence coming from the plate, improving the UV image quality. 

SWISSCI’s UVXPO polymer also has the same low auto-fluorescence while also showing uniform zero background when imaging using cross-polarised light. This makes it our most advanced polymer to date.
