The GemBio Moxi-V. Available from Meritics in the UK

Gold Standard Cell Counts, Cell Size, and Viability.

The Moxi V™ provides a combination of volumetric cell sizing (Particle Sizer) with simultaneous fluorescence (Flow Cytometer) to provide the most accurate cell counts, size, and viability in the industry. Specifically, the Moxi V™ employs the Coulter Principle to precisely measure the volumetric particle size of each particle for exact size measurements down to 3µm in diameter (14fL volume), easily distinguishing between cells and debris.

The system is also equipped with a 532nm laser and a 561nm/LP detection channel for robust cell viability analysis. Propidium Iodide (PI)-stained dead cells measure 50-100 times brighter fluorescence on the system than do live cells, removing the ambiguity associated with traditional Trypan Blue viability assessments. For each test, these size and viability measurements are applied, individually, to up to 23,000 cells in a matter of a few seconds.

This ensures the highest level of precision and statistical robustness. As the fluidic volume is precisely metered as well, the particle counts are presented as an exact cell concentration.
