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.
Quantify E.coli & other coliform bacteria in water samples according to ISO 9308-1: 2014 standard, in the laboratory and in the field. LetzTest has developed a portable membrane filtration kit that is perfectly adapted to the requirements of a water testing laboratory in limited infrastructure conditions:
(i) robust, (ii) electricity-free, (iii) high in quality, (iv) easy to transport, (v) easy to use, (vi) independent of inappropriate consumables, (vii) not prone to human errors.
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.
