Bacteriological Field Test Kit (H2S Vial)
A compact, field-friendly water-testing solution for preliminary screening of bacteriological contamination — no laboratory equipment required at the point of testing.
The Bacteriological Field Test Kit (H2S Vial) is a compact, field-friendly water-testing solution for preliminary screening of bacteriological contamination in water. It gives an easy-to-interpret visual result at the point of testing, without needing laboratory equipment or electricity — suited for drinking water surveillance, rural monitoring, field surveys, community water-source assessment, and routine bacteriological screening programmes.
Uses
- Drinking Water Surveillance: Enables quick, preliminary screening of drinking water sources for bacteriological contamination at the point of testing.
- Rural & Community Water Monitoring: Screens water from wells, borewells, and community sources across villages where lab access is limited.
- Field Water Quality Surveys: Used by water-quality field staff, government monitoring teams, and NGOs for on-the-spot assessment before samples go for lab confirmation.
- Decentralized Monitoring Programmes: Scales screening from water source to village to block to district level, referring positive samples for confirmatory lab testing.
- Schools & Institutional Screening: Suitable for educational institutions and emergency/disaster situations needing quick initial water safety checks.

It is a compact, field-friendly water-testing solution designed for preliminary screening of potential bacteriological contamination in water.
The H2S Vial provides a quick preliminary indication of possible bacteriological contamination, helping users identify water samples that may require further laboratory analysis.
Add the water sample to the reagent vial and observe the colour change over the incubation period. A change from clear to black indicates a positive preliminary indication of bacteriological contamination.
No. The kit is designed for preliminary field-level screening with minimal supporting equipment and does not depend on sophisticated instruments or an electricity supply.
It can be used by trained field personnel, water-quality field staff, government monitoring teams, public-health teams, NGOs, educational institutions, and other users conducting routine water screening.
It is suitable for drinking-water screening, rural water-quality monitoring, community water sources, wells and borewells, schools, field surveys, government monitoring programmes, and emergency or disaster situations.
Yes. It has a compact, field-ready format and is conveniently packed for transportation and use across villages, rural communities, schools, water sources, and remote locations.
The bacteriological vials are available in packs of 10, 50, and 200.
The kit contains a sterilized glass vial with paper impregnated in an appropriate medium, along with a user guide.
No. It is intended for preliminary screening only. Confirmatory laboratory microbiological analysis should be used where quantitative, validated, or regulatory results are required.
