Uses of instruments 

Manufactured by our company WFH-201B、202（B） Multifunctional UV transmitter for DNA、RNA Detection and photography of electrophoretic gel samples.

And suitable for public security fingerprint inspection and criminal photography, especially newly developed and 300 nm Test wavelength, can be used specifically for“ P、C、R、”（ Gene amplification technology) UV analysis.

Make the performance of the instrument reach the level of similar products abroad. It is an essential instrument for bioengineering, molecular genetics, biochemistry, medicine and health, biological products and other units.

The ultraviolet lamps, color filters and color filters used in our factory have been precision-processed and have the best quality domestic production.

Therefore, the ultraviolet output of this instrument is strong and uniform, which greatly shortens the time for shooting samples, and the negative film is clear and without stray background light.

Instrument structure

WFH-201B The fully enclosed multi-function ultraviolet transmission reflector consists of two parts: the machine base and the fully enclosed cover box. The fully enclosed cover box is equipped with an observation window and an adjustable photo frame is installed on the top of the box. A set of transmission devices are provided in the base with a wavelength of 300 nm, Color filter size: 200 ×150（mm）, Equipped with 8 light tubes. Two sets of reflective devices are provided in the fully enclosed cover box, with a wavelength of 254 nm and 365 nm， Each is equipped with 2 lamp tubes.

WFH-202B Fully enclosed PCR Ultraviolet transmitter, except for the non-reflective device, other indicators and WFH-201B The same type. WFH-202PCR UV transmitter, no dark box.
