Multiplate® analyzer 3 Overview
Multiplate technology
Multiplate technology
The analyzer is a platelet function analyzer based on impedance aggregometry. Two
pairs of electrodes are immersed into the stirred blood sample. When platelets
aggregate they adhere to the electrodes and change the electrical resistance (or
impedance) between them. The change in resistance during the analysis is
continuously recorded.

The analyzer uses the innovative multiple electrode aggregometry (MEA) technology.
Instead of one pair of electrodes, two pairs are located in each test cell; hence a double
determination is performed on each sample. This combination of duplicate sensor
measurements and the use of disposable test cells ensure both high safety and
reliability.
