Although smaller and simpler than their eukaryotic counterparts, bacteria are an incredibly diverse group of organisms that come in multiple shapes, sizes, and arrangements. Colony counting is a highly variable and unreliable, as it is only an estimate of the viable cells present. Even expensive flow cytometers and laser scanning cytometers register each particle, single or clustered, as a single event. The QUANTOM Tx™ Microbial Cell Counter is an image-based, automated cell counter that can detect individual bacterial cells in mere minutes. Its novel bacteria-optimized cell detection software can count individual bacterial cells in even the tightest clusters.
WHAT THE QUANTOM Tx™ DOES BEST


THE SOFTWARE THAT CHANGES EVERYTHING.

INNOVATIVE COUNTING PROCESS ENSURES ACCURATE COUNTS

STAINING QUANTOM™ Total Cell Staining Dye easily permeates both gram positive and gram negative bacteria to stain both live and dead cells. QUANTOM™ Viable Cell Staining Dye efficiently labels viable bacteria. |

IMMOBILIZING Stained cells are mixed with our bacteria-optimized loading buffer, loaded into QUANTOM™ M50 Cell Counting Slides, and spun in the QUANTOM™ Centrifuge to immobilize and evenly distribute the cells throughout the counting chamber to ensure accurate cell counts. |
