General description

Multi-purpose UV appliance: use top stage as a UV transilluminator and the bottom drawer for DNA-membrane binding, nicking, and to form thymine dimers. Also useful for sterilizing small items with UV irradiation.
The top stage is a long-life filter that does not solarize at 312nm, protected by an adjustable viewing shield. Intensity is selectable between 70% and 100%. Uniform illumination is provided by six 15W 312nm bulbs. The top is protected by an adjustable UV safety shield.
The tray, approx. 15 × 25cm, exposes samples on Petri dishes, multiwell plates, membranes, etc., to direct irradiation from four 15W 254nm bulbs. A UV photoelectric cell detects actual intensity, and the unit can be programmed to turn off after a preset UV dose (J/cm2) has been delivered.
Replacement bulbs are available.
