H2S Vials

H2S Vials are specially designed containers used for the detection of Hydrogen Sulfide (H₂S) gas in water samples. These vials contain a selective medium that changes color when exposed to H₂S-producing bacteria, making them a simple, cost-effective tool for monitoring water quality, especially in rural or field conditions. Ideal for microbial testing, they offer quick and visual results without the need for complex lab equipment.
