Pipetting System for Automated Blood Analyzer

Blood analysis requires a sequence of steps that if done manually are very time-consuming. An automated pipetting subsystem can speed the analysis. In such a system a set of pipettes is positioned to aliquot blood samples from primary test tubes and deposit them in secondary tubes. The subsystem must not only be fast but also accurate and smooth in handling the samples.

Allied Motion’s small CL series of coreless DC motors equipped with gearheads drive miniature leadscrews to withdraw or deposit precise amounts of fluid from or to the sample tubes. Quantum series servo motors power the X-Z mechanical translation system that precisely positions the pipetting system during operation.
