DEVICE AND METHOD FOR SELECTION AND PRESERVATION OF BIOSAMPLES IN EXTREME LIVING CONDITIONS Russian patent published in 2014 - IPC G01N1/10 G01N33/48 

FIELD: chemistry.

SUBSTANCE: filter is placed in a separate holder with a hole, a sample is applied on an open part of the filter and after sampling the filter is left in the holder to complete the sample drying. Before sampling, analytic aerosol bilateral filters AFA-X are opened and taken out with pincers from packs of the ZipLock type. The filter is placed on a lower plate of the holder with its working fleecy side towards the hole in an upper plate of the holder. Viniplast holders are used and sampling on the open part of the filter is performed. After the sample drying the filter is removed from the holder, placed in a separate ZipLock pack and kept at the temperature of the environment. The device contains filters, placed in the holder, namely two analytic aerosol bilateral filters AFA-X with one fleecy side and two filter holders from the sheet viniplast, made with a possibility of their fixation to a working table. Each holder consists of rectangular plates - upper and lower, with rounded edges and a hole in the centre, and is provided with a textile fastener from nomex, made from two parts - hook one and loop one.

EFFECT: increased reliability of the device with an increased storage term of the sample.
