Moxi Z Cell Counter

The Moxi Z mini automated cell counter with new OS 4.4 gives you accurate results you can count on.

The Moxi Z OS 4.34 is the only automated cell counter that combines the gold standard Coulter Principle typically used in high-end cell counters with a patented thin-film sensor technology to allow for highly accurate and repeatable particle sizing and counting with a broad dynamic range (3 – 34 microns).

The Moxi Z OS 4.4 also provides a reagent-less assessment of culture health for monodisperse mammalian cultures using a proprietary algorithm to report a Moxi Population Index (MPI).

This revolutionary ultra-small instrument offers characterisation of particulates in a wide variety of common applications, including mammalian cells, RBC, WBC, yeast and more. It is the ONLY automated system that is also able to reliably measure particles with an average diameter as small as 3 microns.

Designed to overcome the tedium associated with hemocytometers, the lack of repeatability with image-based counting systems, and the high complexity and expense of Coulter counters and flow cytometers, the Moxi Z OS 4.4 is truly an automated cell counter in a class of its own.

The new Moxi Z OS 4.4 is the highest performing automated cell counter available.

  • • Measure in just 8 seconds
  • • Obtain cell counts AND size with >95% accuracy
  • • Assess culture health without the use of reagents
  • • Utilize Bluetooth or USB On-The-Go connectivity
  • • Count cells down to 3µm in diameter

Accurate Counts and Size (>95%)

Accurate counts with Moxi Z

Ensure the best downstream experimental results possible. By using the gold-standard Coulter method of volumetric cell counting, the Moxi Z OS 4.4 will ensure that your cell counts are better than 95% accurate the first time. With precision rivalling significantly more expensive Coulter systems (Moxi Z CV: 4% and Z2 CV: 3%), the Moxi Z OS 4.4 out-performs all other low cost systems and provides the accurate data you need, every time.

Not only is the Moxi Z OS 4.4 counting accuracy superior to any other automated cell counter on the market today, it also is the only cell counter with the resolution required to accurately measure particles down to 3µm in diameter. Imaging systems are typically limited to 5-6µm particles. In fact, the Moxi Z 0S 4.4 can easily distinguish particles having diameters that differ by only 2µm, and the histogram signature can be a valuable tool for monitoring changes in cell population.

Reliable Counts, Size and Cell Health

Reliable Counts Moxi Z

We have tested dozens of mammalian cells, yeast, protozoa, algae, and more to validate the precision and operating range of the Moxi Z mini automated cell counter. In addition, we have run adherent, differentiated, suspension, and progenitor cells to ensure reliable performance using both the Moxi Z Type M and Type S cassettes by optimizing each cassette’s integrated anti-clogging “sieve”.

In a comparison with Coulter counting methods, Moxi Z OS 4.4 is shown to have equivalent results to the gold standard for both count accuracy and particle size accuracy. As the data demonstrates, Moxi Z achieves this performance over a broad range of concentrations and particle sizes.

The Moxi Z is also able to provide a rapid, reagent-free cell health assessment. This is uniquely possible with the Moxi Z OS 4.4 because the system creates extremely high-resolution histograms and has superior small particle detection capabilities. The Moxi Population Index (MPI) produces a ratio of intact cells to dying/dead cells (and debris) which provide a snapshot of the general health of your cell culture.

Fast (8 seconds)

Fast - Moxi Z

Moxi Z OS 4.4 counts your cells faster than other automated cell counters and provides results 15-50 times faster than via manual hemocytometry. In fact, Moxi Z OS 4.4 is over 6 times faster than image based systems WITH higher accuracy and precision. With Moxi Z OS 4.4, you will transform your least favourite and least accurate laboratory task into an easy 8 second precision routine.

With an average measurement time of 8 seconds (Type M cassette), the Moxi Z OS 4.4 yields the fastest cell counts of any available technique. Test times for the high-resolution Type S cassettes are just 15 seconds.
