BL12-2 is optimized for high-throughput micro-crystal macromolecular crystallography data collection to high-resolution. BL12-2 also supports advanced serial and time-resolved crystallography methods. BL12-2 is an undulator beam line with a fully adjustable focus. Micron-sized beams (10 x 10 µm2 or 20 x 20 µm2) are achieved with precision micro-collimators. BL12-2 is SAD and MAD capable and can be run in a fully remote access mode.
BL12-1 is designed for investigations of the most challenging macromolecular crystallography systems confronting scientists today, including cases where crystals can only be grown to a few microns in size, serial room temperature studies and time-resolved measurements. BL12-1 supports fully remote-access experiments using samples at cryogenic conditions in uni-pucks or cassettes, and samples at controlled humidity and elevated-temperature conditions using specialized SSRL plates.
