DelAgua Dual Incubator
DWT Code: 10099
Supplier Code: DWT10099
  • Dual Incubation can allow 16 samples of two separate temperature conditions OR 32 samples under the same conditions
  • 37°C incubator chamber for analysis of total coliforms (can be calibrated to 44°C for Faecal coliform analysis) and 44°C incubator chamber for analysis of faecal coliforms (can be calibrated to 37°C for total coliform analysis)
  • Can carry out 6 tests to measure the quality of drinking water - microbiological quality at 2 temps. of incubation, turbidity, free chlorine, total chlorine and pH
  • Membrane filtration unit using 0.45μm pore size membrane filters
  • Can be run from DC power adaptor or the separate external battery pack
Twin chamber kit can test at two different temperatures simultaneously, allowing Total Coliform testing in addition to those available in the single.
DESCRIPTION

The Oxfam-DelAgua Dual Incubator Kit, designed for microbiological water monitoring via detection of indicator organisms, (faecal coliforms), for E. coli, cholera, salmonella and other faecal water borne pathogens, is the most popular portable water testing system in the developing world. It is designed to help provide information about the safety of water supplies in difficult situations where laboratory facilities do not exist. The Dual Incubator comes with a separate battery back and can test up to 32 samples at once.

The kit is primarily used in the field, but may also be used in a laboratory or other permanent location. The kit can be supplied with a range of accessories and upgrades that will increase the scope of your water quality monitoring. It has been upgraded into a Pelican Case for easy carrying and durability. Each kit is provided with a complete pack of consumables for 200 plates and a range of spares and replacement parts are available for all equipment and apparatus. Please enquire for details.

 You will need the following items to start testing:

  • Pressure cooker or portable steriliser or access to an autoclave e.g. in a hospital.
  • Methanol (approx 1 ml per test)
  • Distilled water
  • 1 litre measuring cylinder or beaker
  • Clean Cloths

The kit will perform the following tests:

Thermo-tolerant (faecal) Coliform Count: The kit includes a portable, battery-powered incubator capable of making five cycles of incubation without mains electricity, generator or vehicle power. 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: Simultaneously to the thermotolerant coliform testing, total coliform counts can be obtained within 14 to 18 hours of sampling giving a reliable indication of the integrity of a reticulated system or well from ground water ingress without need for transport or laboratory facilities.

Turbidity Test: A measure of the amount of suspended matter in a water supply. Suspended material may consume chlorine disinfectants and require treatment before disinfection.

Chlorine & pH Tests: Many emergency water supplies are dosed with chlorine disinfectant to ensure their safety as drinking water. These tests allow rapid assessment of chlorine levels and aid the efficient control of dosing thereby ensuring that enough chlorine is present to safeguard the supply.

Other Tests: A conductivity meter can be provided as an optional component of the kit. Conductivity provides an indication of contamination e.g. saline intrusion or sewage pollution. Additional equipment can be included on request to test for chemicals that may be of local importance.
