Why is the Wagtech™ Potalab+ suitable for you? The Potalab+ is the most advanced portable water quality laboratory. With complete digital instrumentation, the Potalab+ delivers laboratory levels of accuracy and is inclusive of digital arsenic testing. The kit is ideally suited to longer-term surveillance and professional monitoring in rural locations. To compare this with our other Wagtech™ kits click here.
Chemical tests for ammonia, arsenic, free chlorine, total chlorine, fluoride, nitrate and nitrite
Physical tests for turbidity, pH, conductivity, TDS and temperature
Microbiological tests for thermotolerant or faecal coliforms and total coliforms
High capacity microbiological analysis Dual incubators with independent temperature control for simultaneous determination of up to 40 samples for thermotolerant or faecal coliforms and total coliforms.
Advanced physico-chemical analysis A combination of instruments and reagents allows users to analyse a wide range of physical and chemical parameters to ensure drinking water quality and assess risks against short-term and chronic health effects.
Complete data management Download incubator data and add colony counts for a complete microbiological report. For full traceability of results transfer data from your Photometer 7500 via USB.
Palintest is proud to have a long and established partnership with the humanitarian and development sector, providing technologies which safeguard water for everyone, every day. As challenges in this sector continue to evolve, our Wagtech kits have been adapted to the growing needs of the WASH sector.
The membrane filtration (MF) method can be used to reliably test large numbers of water sample, and is US EPA approved for measuring coliforms.
The water sample is filtered through the membrane filter using a vacuum to pull the water through the membrane. The membrane filter is then placed onto a nutrient source gel in a petri dish and incubated for 24 h at 37 °C. The Coliform and non-Coliform colonies can then be counted. Often pH indicators are used to distinguish between different colony types.
How do I clean my photometer?
Photometers should be regularly cleaned to ensure that your instrument is reading correctly and is not affected by dust or water marks.
To clean a compact or Lumiso photometer, place a small amount of anti- static cleaning foam on to a lint free cloth and wipe the instrument.
For multiparameter photometers, you should clean several parts of your instrument. To clean, place a small amount of anti- static cleaning foam on to a lint free cloth and wipe the instrument.
The first image shows the surface around the sample holder, all visible marks on this area should be removed
Outside optics base plate.
Turn the instrument over and undo the two screws on the base of the instrument, as demonstrated in the second image. Gently wipe the curved areas near the LEDs and the flat area on the opposite side.
Inside optics base plate
Contamination on the inside of the base plate can migrate onto your calibration tubes leading to scratches which damage the standards. If marks cannot be removed from the base plate, a new base plate should be fitted.
When refitting or replacing a base plate, you must ensure screws are tightened so that the standards are set are the correct height. Failure to do so can lead to compromised results.
What is a reagent?
Reagents are the chemicals we incorporate in to our tablets (and in some cases liquids or powders) which are needed as the fundamental components of the test.
