The ProtoCOL 3 comes inclusive with both colony counting and inhibition zone measuring ability. To extend its range of applications, inexpensive additional modules can be added to the software.

• Spiral plate: You can read spiral plates generated from all major spiral plater manufacturers, to generate CFU/mL results automatically.
• Opsonophagocytic killing assay (OPKA): you can count colonies on OPK assay plates to automatically assess the potency of a range of viral vaccines.
• Ames testing: to determine the mutagenic activity of different chemicals, you can count colonies and automatically compare plate results.
• Multi-sector: you can count colonies on plates which are divided into different sections, making this module ideal for use with air monitoring plates
• Serum bactericidal assay (SBA): to determine the efficacy of specific bacterial vaccines you can count colonies on SBA plates
• Multi-well: this enables you to count colonies within individual wells of multi-well plates
• Chromogenic ID: this allows you to automatically identify microbes on chromogenic agar from many of the major media suppliers
