Water Testing Kit, Microbiological, Dual Incubator - with Battery

Portable water quality, bacteriological testing kit to measure for total coliforms and faecal coliforms. With the dual incubator the user can either increase the number of tests per cycle or test for thermal tolerant and total coliforms in the same cycle by setting them at different temperatures.

This unit has an internal, rechargeable battery which can provide power for up to five cycles of incubation without mains electricity. The kit includes consumables for 200 tests.

The incubators in this unit are fully adjustable for temperature and incubation period enabling a full range of tests to be carried out with the equipment.

User notes

You will need the following items to start testing:

• Pressure cooker or portable steriliser
• Methanol (approx. 1 ml per test)
• Distilled (de-ionised) water
• 1 litre measuring cylinder or beaker
• Cigarette lighter

A room (or area) set up as a laboratory with fridge (to store consumables) and sterilising facilities is recommended.

Thermo-tolerant (faecal) Coliform Count
The incubator can be set to a required temperature. At 44°C thermo-tolerant (faecal) Coliform counts can be obtained within 14 to 18 hours of sampling, giving a reliable indication of sanitary risk without need for transport or laboratory facilities.

Total Coliform Count
The incubators can be set so that tests can be carried out at both 37°C and 44°C. The lower temperature is used for the determination of total coliforms. Coliform counts can be made within 16-18 hours and give an indication of contamination of water supplies from environmental and other sources.
