The usage of our Compact Dry EC Plates is a simple and safe way for the determination and quantification of E.coli and other coliform bacteria in water. Especially for settings with relatively poor infrastructure. The plates consist of a special 50 mm diameter petri dish containing a detection specific dry nutrient pad for E. coli and other coliforms. The medium contains two kinds of chromogenic enzyme substrates: Magenta-Gal and X-Gluc. Due to these substrates E.coli forms blue to blue purple colonies while coliforms show a reddish, red violet or pink coloration. The total coliform group count is the sum of all colonies identified as coliforms or E.coli.
Membrane Filtration Device - product information sheet
For quantitative analysis the membrane filtration procedure is the standard procedure for use by water testing laboratories for detecting the presence of E.coli and total coliform bacteria in drinking, waste and surface water. For this technique a filtration unit is required. LetzTest offers a stainless steel membrane filtration device which is perfectly adapted to the needs of a water testing laboratory in a developing country.
The right choice of instrumentation & consumables - information sheet
What very often hinders the development of water testing capacities is the wrong choice of Instrumentation & consumables. We consult organisations in making the right choice of equipment to securely build up the capacity to perform water quality analysis in a developing country.
Laboratory Quality Management System - information sheet
A water quality testing laboratory needs a solid quality management system to assure accuracy and reliability throughout the path of workflow, and as a fundamental basis for a possible ISO 17025 accreditation. We consult organisations in building up a solid laboratory quality management system.
Running a baseline study on drinking-water quality is essentail for many water & sanitation projects. Trustworthy results are the basis for many decisions to be taken. We consult organisations on how to perform a professional baseline study and support them to built that capacity on the ground.
