Abstract

See full text

An apparatus which provides an automatic, signal controlled, sample mixing/resuspending, aspiration and delivery system; wherein a demountable, rotatable carousel temporarily holds a multiplicity of sample containers. Electro-mechanical means, including optical sensors, is programmed to automatically move the carousel to a pre-selected position. A self centering vortexer/mixer lifts a selected sample container from the carousel, sealingly engages the sample container within a sample container support and thereafter orbitally mixes and resuspends the sample container contents. An aspiration probe enters the sample container through the support to receive the sample, which is forced out of the sample container by means of compressed air introduced into the sample container via the sample container support. The sample is delivered to an operably associated flow cytometer via the aspiration probe, after which the probe is washed and readied for the next cycle of operation.
