H2S Strip Test Kit
What is H2S Strip Test Kit?
LTEK's H2S Strip Test is ready to use simple device based on hydrogen sulphide indicator bacteria for carrying out bacteriological examination of drinking water.
The Hydrogen Sulphide Paper Strip Method.
The Hydrogen Sulphide Paper Strip Method developed by Manja et al. (1982) is an on site testing method for the microbial quality of drinking water and is based on the detection of hydrogen sulphide producing bacteria rather than the coliform bacteria. Human faeces contain a high concentration of sulphate reducing bacteria of up to 1010/g (Levett, 1993) and some of the enteric bacteria such as Salmonella, Proteus, Citrobacter and some strains of lebsiella,also produce hydrogen sulphide.
Sterlized paper strip treated with media is kept in sterlized glass bottle. The water sample is filled in the bottle and kept for 24
to 48 hours at room temperature (25 to 37 C).
If bacteria are present in the sample, they produce hydrogen sulphide, which turns water sample black.

Features of H2S Strip Test Kit-
|1) ||Ready to use:
The water sample (20
ml) from the source can be directly taken in to the pressurized
H2S Strip Test bottle. Presterlized bottle contains premeasured sterile media on paper strip. There is no need of
preparation and sterilization
of media or sterilization of bottle. Bacteriological test of sample water (20 ml) starts at sample source. || |
H2S Strip test kit's bacteriological test is so simple that even a layman can perform it. For the reason it is most suited for rural
& remote areas and for those who do not have infrastructure to
carry out standard microbiological
tests. || |
|3) ||Economical: H2S Strip test kit is most economical proposition. It does not require any set up or laboratory or services of microbiologist. || |
|4) ||Portability: H2S Strip Test Kit is made up of glass, light in weight, easy to carry
anywhere, anytime. || |
|5) ||Disposable: Destroy
after use. || |
Results are reliable, meaningful and reproducible. || |
|7) ||Illustrative Direction:
Simple to follow illustrative direction are given which explains the use of the test kit. || || |
