Easy Colony Counting

New and Simple Bag Field Test



Count E. coli Colonies Without Membrane Filtration


Anyone with little training can use the GEL EC CFU Kit to obtain precise colony counts of E. coli bacteria in the field. Blue/blue-purple E. coli colonies are easy to identify and count in our plastic GEL bag.

Now you can do on-site quantitative testing using our CFU (Colony Forming Units) GEL method without needing complicated membrane filtration tests and equipment.

Using just a small number of plastic consumables like our CBT EC+TC Kits, the GEL EC CFU Kit eliminates the need for laboratories, electricity, expensive equipment, a cold chain and complex testing methods. GEL Kits also enable ambient temperature incubation at 25ºC and above and work at variable temperatures.
