Wagtech Potatest

  • PTW10005

Widely used by organisations involved in large-scale emergencies or simple water quality testing projects, the Potatest is a lightweight microbiological test kit offering low-cost, rapid response testing of basic water quality parameters.

Designed to complement the increased emphasis now being placed upon water safety plans (WSPs) and their role in assessing and managing risk throughout each step of the drinking water supply process:

  • Removable water safety kit (WSK) – contains instruments and visual test equipment to determine whether a full microbiological verification is required
  • Rapid field microbiological analysis – using membrane filtration protocols for screening of faecal and/or total coliforms
  • Supplied with consumables and parts sufficient for processing/analysing 200 samples.

The Wagtech Microbiological Incubator

Drawing on decades of experience in field microbiological analysis, the latest Wagtech incubator combines tough hardware with simple-to-use methods and advanced operator controls. The system can incubate up to 20 samples simultaneously, features user and sample ID settings, user-defined temperature settings, automatic calibration, audible instructions, and USB connectivity for data management.

Voice Instructions

The Wagtech Incubators all feature a high-volume audio speaker to deliver audio prompts that work in conjunction with the included Prompt Cards. Together the two provide clear and concise instruction to key stages of the test procedure. Users can also record and upload their own instructions onto the device; useful for providing your own instructions on to teams using the kits, and/or recording in additional languages.

Microbiological Testing Prompt Cards

These illustrative step-by-step guides, which are linked to voice instructions in the incubator, cover: Preparation of Culture Medium, Sterilising the Membrane Filtration Unit, Petri Dish Preparation, Membrane Filtration of the Sample, and the Analysis of Microbiological Results.

Nutrient Pad Sets

Wagtech kits use Membrane Lauryl Sulphate Broth (MLSB) as the growth media for enumerating Total and Thermotolerant Coliforms. A range of Nutrient Pad Sets are then also available for use with the Wagtech Incubators, to measure other target organisms such as E. coli.
