TRAWAS is a complete portable microbiological laboratory for testing drinking, recreational and waste water as well as beverages.

Tests for coliform bacteria and Escherichia coli (E. coli) by the membrane filter technique (see ISO 9308-1) are the most important routine microbiological examinations carried out on drinking water.

The TRAWAS laboratory conforms to ISO 9308-1.

This kit has been developed 1997 in cooperation with Messrs. SARTORIUS AG, Göttingen who provide the media (Nutrient Pads) and filtration equipment.

Main components are produced by Messrs. SANDBERG & SCHNEIDEWIND. The TRAWAS kit is unique as we can guarantee stable incubation temperature using a special carrying case which can balance the temperature while connected to the incubator thus ensuring that samples are not overheated during incubation (i.e. at high ambient temperatures) which is essential for the test.

Operation ManualAll components are of highest quality (working parts are made of stainless steel) and can be used either in recognized laboratory for every day work or under rough conditions in a remote area.

Incubator INCUS .3
 
WHO Guideline
The incubator is designed to provide a stable temperature environment. It can be used stand-alone or in conjunction with the coolbox depending on ambient temperatures.
Bacteriological quality of drinking-water according to World Health Organisation (WHO)

Filter Method
 
Solar Station
Tests for coliform bacteria and Escherichia Coli (E.Coli) by the membrane filter technique (see ISO 9308-1) are the most important routine microbiological examinations carried out on drinking water.
The kit can also be supplied with a solar power station to provide sufficient electricity to run the Water Testing Kit independently.
