Abstract
An automated specimen preparation system for preparing a specimen from a sample in a sample container is provided. The automated specimen preparation system comprises a specimen transfer device configured for holding a specimen collector thereon and for being positioned within the sample container. The specimen transfer device comprises a central bore having an open distal end and a closed proximal end, a pressure monitoring port fluidly coupled to the central bore at the proximal end of the central bore, and a fluid waste evacuation port fluidly coupled to the proximal end of the central bore. The pressure monitoring port comprises a reduced diameter portion coupled directly to the central bore. The automated specimen preparation system further comprises a vacuum source fluidly coupled to the fluid waste evacuation port, and a pressure monitoring device fluidly coupled to the pressure monitoring port.
