Spectronics Corporation has introduced a new high quality, inexpensive ultraviolet crosslinker that makes it possible to identify and analyze trace amounts of DNA/RNA with far greater sensitivity, accuracy and speed than with conventional analysis.

The Select^TM XLE-Series UV crosslinker covalently binds nucleic acids to membranes in under 30 seconds - 240 times faster than vacuum-oven baking! It has a unique true-UV-monitoring circuitry that safeguards valuable test results from washouts, even when the tubes age.

Researchers also rely on this versatile 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 Select Series crosslinker features a "smart" user-friendly, fully programmable microprocessor, built-in "help" messages and an auto-repeat function that make its operation amazingly fast and simple. It features five 8-watt tubes and is available in a choice of 254nm, 312nm and 365nm versions.
