Benchtop viable cell analyser

Using the capacitive sensor technique as the means for accurate analysis, the Aber 820 analyses viable biomass concentrations within a few seconds with accuracy and repeatability, eliminating dilution and manual counting under a microscope. In many cases such as highly clumped, filamentous or immobilised cells on carriers, the instrument provides a solution for estimating the viable biomass concentration.

The Aber 820 is insensitive to cells with leaky membranes, gas bubbles and cell debris in a wide range of media.

Applications include: animal cells in suspension, or attached to microcarriers; fungal or filamentous bacterial cells grown in simple or complex media; yeast cells grown with high conductivity; and bacteria in high-density fermentations.

The Aber 820 measures the following units: viable cells (0 to 9.99 x 106 viable cells/mL); dry weight (0 to 140 g/L dry weight); percentage solids (0 to 70% solids by volume); and conductivity (1 to 36 mS/cm).

Calibration factors for up to 10 different cell types or strains can be stored in the instrument. The sample size is 10 mL, but smaller sample cells are available as options, eg, 200 µL.

An RS232 port is provided for data transfer to a PC.
