[Polarographic cell for the microanalysis of biological substances]. / Poliarograficheskaia iacheika dlia mikroanaliza biologicheskikh veshchestv.

A polarographic cell is developed for two-electrode polarographic analysers to be used in mass clinical testing. The cell enables testing samples of as small volumes as 0.1 cm3 because its working part is made in the form of a tubular channel of a small diameter and a reference electrode is isolated from the cell working channel with a filter passing ions through. The cell may be arranged to operate in autoanalyzers with continuous and intermittent sampling.

[Flow-type pulsatile cytofluorometer with increased sensitivity]. / Protochnyi impul'snyi tsitofliuroimetr povyshennoi chuvstvitel'nosti.

A new cytofluorometer is described, with sensitivity twice as high as that of the existing units.
