Home  /  Colony Counters  /  AutoCOL

A fully automated colony counting system

Featuring an integrated plate feeder, colony counter and software based on Synbiosis’s tried and trusted ProtoCOL technology, an AutoCOL can automatically remove your plate lids and count colonies on up to one hundred, 90 mm plates in under an hour.

Simple software

With intuitive touch-screen software you connect to AutoCOL via USB, you can easily set up automatic plate reads and optimise batch design for each plate type. You can set user access levels and even set up pass/fail limits enabling your AutoCOL to track and stack all pass/fail plates in specific places in the plate feeder. bla

Accurate counts

Combining unique three colour lighting and a sensitive camera, with an AutoCOL you’ll capture full colour images of all microbial colony types, to generate precise, reproducible counts.

Fully traceable

Compatible with 1D barcode readers, you can export images or numerical results automatically from an AutoCOL into a range of formats (XLS, PDF, CSV) or to your LIMS. This ensures your data is secure and has a complete audit trail, making it fully 21 CFR Part 11 compliant.

Flexible applications

AutoCOL is perfect for high-throughput colony counting and is being trialled in highly regulated pharmaceutical and contract research microbiology laboratories for a wide range of microbial colony counting applications including:

  • Microbial environmental monitoring
  • Microbial limits testing
  • Efficacy testing
