Product Introduction
The cassette is a tool for signal collection under dark conditions. It is operated in a dark room and the film is pressed into the cassette, which can well fix the relative position of the film and the film. The signal on the membrane is well reflected on the film, which is a good helper in the darkroom exposure (western).

Instructions for Use

The first step, the placement of the signal source (membrane): place the membrane incubated with the luminescent solution in the middle of the dark box, and cover the membrane with a layer of transparent film;

The second step is to adjust the appropriate infrared light intensity, turn off other lights in the dark room, so that only infrared light exists in the dark room, take out the film under the condition of infrared light, cut the appropriate size, make a mark, and press it on the film, Then close the cassette and time;

The third step is to take out the film in the cassette for development and other operations.

Notice
1. Keep the surface and interior of the cassette clean and tidy, because the dirt may have fluorescent signals, which will adversely affect the results.

2. When using the cassette, pay attention to the segmentation of white light and infrared light. When collecting signals on the film, the placement of the cassette should avoid white light as much as possible.
