PIPETTE INSTRUMENT

摘要

A pipette instrument 100 carrying interrogation circuitry 132 adapted to interrogate a data signal received from a removable instrumented pipette tip 114. The pipette 100 includes a microprocessor and memory 130 that can be programmed to perform data collection procedures. User controls typically include a start button 108, and a track wheel 1 10. A display device 1 12 can present device options through one or more menu, and show data resulting from one or more test result. The pipette can interrogate particles carried by a fluid flowing through a tip 1 14 by detecting either of or both of Coulter principle phenomena, and Stokes-shift phenomena.
