Aquagenx GEL EC Kit

Easier, Faster CFU Test Results in the Field

Compare the Aquagenx GEL Kit to Other Tests

The GEL EC CFU Kit is simple and easy to use. Users count E. coli colonies right in our GEL Bag

It does not need membrane filtration equipment, complicated procedures or intensive training.

See how our GEL EC CFU Kit compares to membrane filtration CFU water quality test kits and methods.

Compare to IDEXX Colilert

The World Health Organization (WHO) engaged KWR Laboratory to evaluate the Aquagenx GEL EC CFU Kit against standard method IDEXX Colilert 2000. The report yielded outstanding results.

Download PDF of Table	Aquagenx GEL EC CFU Kit	Membrane Filtration Methods
Testing method	Colony Forming Units (CFU)	Colony Forming Units (CFU)
Microbial indicator	E. coli	Depends on product/system: Thermotolerant (fecal) Coliforms; E. coli
Usability	Easy for anyone to use, designed for field testing	Requires intensive training, challenging to use for field testing
Portability	Lightweight, easy to carry and transport	Can be heavy and/or cumbersome, multiple components
Incubation	Ambient temperature incubation >25° Celsius	Requires incubator and temperature control
Components	Thio-Bag, GEL Bag, E. coli medium, GEL powder	Filter and funnel apparatus, vacuum system (vacuum flask and vacuum source, typically an electrical pump or a vacuum line in a lab) or large syringe, culture plates, petri dishes, gridded membrane filters, multiple measuring devices, absorbent pads, volume dispensers (e.g., sterile pipettes and/or graduated cylinders or centrifuge tubes with volume marks), tweezers, heat source to flame tweezers
Procedures	Eight easy steps	Time consuming with multiple steps: equipment set-up and preparation, culture media preparation (or costly sterile media in ampoules), sterilization of multiple pieces of equipment
Growth medium storage	Store at 10-25° Celsius in a dry environment, refrigeration is optional	Requires refrigeration and cold chain
Post-test disposables and reusables	No reusables to clean or sterilize. To decontaminate sample, add liquid bleach or chlorine tablets to GEL bag. Or, treat with heat >60°C. After 30 minutes, pour contents into a sink, toilet or hole in ground and safely dispose the GEL Bag with solid waste.	Disposables: Petri dishes (and possibly sample collection bag, large syringe for pulling a vacuum, disposable pipettes and disposable graduated centrifuge tubes) that must be decontaminated prior to disposal (e.g., with heat >60 degrees C or free chlorine). Reusables: Multiple materials and equipment that require decontamination, cleaning and sterilization (e.g., filter apparatus, pipettes and/or graduated cylinders, vacuum flask, sample collection bottles, etc.)
