This opportunity is for a Multisizer instrument that uses the Coulter method to measure cell size, counts, and distribution across multiple clinical research study protocols. The system must include digital pulse processing, automatic aperture blockage detection, bar code scanning, and fluid level monitoring. It requires a particle sizing range of 0.2–1,600uM, measurement linearity of ±1% in diameter, and the ability to process up to 525,000 time-stamped pulses per analysis. The instrument must support 100uM and 400uM aperture tubes, 100/200mL beakers, and specific solutions and standards for operation. No timelines, budget amounts, or performance location were specified in the description.
