UV Crosslinker

Spectronics Corporation has introduced an ultraviolet crosslinker for identifying and analyzing trace amounts of DNA/ RNA with sensitivity, accuracy and speed. The Select XLE-Series UV crosslinker covalently binds nucleic acids to membranes in less than 30 seconds — 240 times faster than vacuum-oven baking. It has a true-UV-monitoring circuitry that safeguards valuable test results from washouts, even when the tubes age.

Researchers also use the instrument for eliminating PCR contamination, nicking ethidium-bromide-stained DNA in agarose gels, gene mapping for creating cleavage- inhibiting thymine dimers, RecA mutation screening in E.coli, UV sterilization and miscellaneous UV-dosage applications. The crosslinker features a user-friendly, fully programmable microprocessor, built-in “help” messages and an auto-repeat function that make its operation fast and simple. It features five 8-watt tubes and is available in a choice of 254 nm, 312 nm and 365 nm versions.
