Automated Colony Counting and Zone Sizing

Affordable Automated Colony Counting and Zone Sizing

ProtoCOL is a comprehensive and fully automatic colony counting and zone sizing system specifically designed for microbiology and virology applications. This colony counter and zone sizer system is suitable for reading a wide range of types of microbiology and virology media. Colonies can be automatically counted on standard pour plates, surface inoculated plates, spiral plates, 3M ™ Petrifilm ™, filters, culture flasks and numerous other media. Zones can be automatically measured for potency testing, antibacterial susceptibility and virology applications

ProtoCOL has been designed to offer the microbiologist full compliance with Good Laboratory Practice and support of 21CFR Part 11

ProtoCOL 3 is the next generation instrument for colony counting, zone measurements (inhibition and antibiotic susceptibility testing (AST), membranes, Petri-film and a range of other applications including: spiral plates, OPKA (opsonophagocytic killing assay), SBA (serum bactericidal assay), Multi-sector, Multi-well, SRD (single radial immunodiffusion) and Ames. The new design now enables plates of up to 150mm diameter to be automatically read at the press of a button. Designed for use across a wide range of applications, ProtoCOL 3 will count colonies as small as 43 microns (0.043mm) or measure zones accurately to 0.1mm.

ProtoCOL 3 has a unique LED lighting system configured for exceptional illumination of all sample types. High definition, colour images taken with a 1.4 mega pixel scientific grade CCD camera ensure that even the smallest colony can be seen and counted, while zone measurements are fast, accurate and reproducible.

ProtoCOL 3 is available with a mounted touch screen processor which enables ease of control while the easy-to-use software produces highly accurate results. Alternatively, the ProtoCOL 3 can now be used with a new or existing stand-alone desktop or laptop computer via USB connection – no additional PCI cards are required.

The new ProtoCOL 3 comes inclusive with both colony counting and zone measuring ability. To extend its range of applications, inexpensive additional modules can be added to the software for Spiral, OPKA, SBA, Multi-sector, Multi-well, SRD and Ames. Results can be automatically transferred to Excel or a LIMS system. The system can also be used with 1D and 2D barcodes. All data generated is GLP/GMP compliant with a full audit trail and can be used to produce professional reports. Each system comes complete with 2 validation plates.
