[A set of check-up means for an automatic microplate photometer for immunologic studies]. / Komplekt sredstv poverki avtomaticheskogo planshetnogo fotometra dlia immunologicheskikh issledovanii.

The title set consists of six pairs of neutral filters with different optical density ranging from 0.03 to 1.5 B, a pair of filters made of colour yellow glass, and a holder having the same dimensions as the microplate and serving for the installation of the filters in the photometer checked. Every pair consists of two filters with identical optical parameters. The dimensions of the pair of filters allow covering all eight channels of the photometer simultaneously. The filters are certified with the error not more than +/- 0.003 B in the spectral range 360-700 nm. The yellow glass filter allows checking the dual wavelength mode of investigation.

[Microfluorimeter for biomedical research]. / Mikrofluorimetr dlia mediko-biologicheskikh issledovanii.

A new microfluorimeter built on the basis of the fluorescence microscope scheme is described. The study object is illuminated on the reading side. The device is highly sensitive and allows small amounts of fluorescent agents to be investigated. The microfluorimeter has been used to study the absorptive activity of the gastrointestinal tract.
