1) incubator for lasting incubation without shaking of micro quantities (insect, plant cell cultures, etc. ) in immunoplates; 2) microplate shaker for operation in the cold room or other conditions, which do not require temperature stabilisation; 3) microplate thermo-shaker for immunochemistry and molecular diagnostics, where the requirements to the result reproducibility and thus to the precise method regulation are particularly high. The device can be used in: 1) cytochemistry for in situ reactions 2) immunochemistry for immunofermentative reactions 3) biochemistry for enzyme and protein analysis 4) molecular chemistry for matrix analysis
