Handheld UV Transilluminators
These can be supplied with and without genuine quartz filters. Quartz filters pass fixed UV wavelength and no visible light or infra-red light to give a pure UV output. Handheld illuminators without quartz filters will have a slight bluish illumination.
These have twin high intensity UV tubes, white LEDs or Blue 470nm LEDs. Electronic high frequency ballast to give instant start and no humming. Low heat generation. Suitable for academic, research and medical applications.
UV handheld illuminator can be single wavelength or dual wavelength - 254nm or 302-312nm or 365nm.
White Light Transillumination
Suitable for general observagtion and for protein gels
Blue Light Transillumination
Suitable for observing gels stained for blue light illumination.

* Please note that 300nm, 302nm, 306nm and 312nm are in the same range of wavelengths called UV-B (also known as mid-range). Some manufacturers quote 302nm but it is the same as 312nm. Similarly, 254nm, 255nm and 256nm are the wavelengths in short-wave; 360nm and 365nm in long-wave.
