Photochemical Reaction Experiment Device

It is a compact photochemical reaction experiment device in which a UV light source is used.

1. Outline

There are two types of UV light sources: high-pressure mercury lamps and low-pressure mercury lamps.
The standard reaction tank has two sizes: 500ml and more than 1500ml. To work out the suitable size for respective light sources, refer to Table 1.
Reaction tanks other than the standard type can also be designed/created by using various
customized specifications such as using lamp power of more than 3kw, a type in which both UV and ozone are used, etc.

Note 1 : Letters at the end of the model of the lamp jackets (Q/G) refer to materials of the jaket.
Q stands for the fused quartz glass and G stands for Hard glass (Pyrex glass).
Note 2 : Three sort of glasses are used for arc tubes of lamps. The lamp with a code H in front of a hyphen (-) of the model are made of fused quartz glass. We have other lamps with a code L and S. L is an ozone free and S has a highest transparency for 185nm ray.
Please contact our staff in charge regarding the details.

4. Appendix

Table 4 shows the spectral radiant energy of various mercury lamps. Though the value of UVP-20H is not yet obtained, the illumination of the 254nm line can be measured. 11SC-1 (PenrayLamp) data can be used as a reference to know the spectral radiant energy tendency of low-pressure mercury lamps.
