Bacteria Growth Check for water quality testing is ideal for spot checks when bacteria presence is suspected. If an area is suspect for bacteria, either dip a test strip into the sample, or, for surfaces, add deionized/distilled water and swab. Insert the test strip back into its package and leave undisturbed for 48 hours at room temperature. Fastidious growth of total micro-organisms is demonstrated by the development of growth colonies on the test strip pad. Match the pad to the closest pattern match to determine an approximate bacteria count. Once a determination has been made, a decision to investigate using more enhanced bacteria testing measures can be more easily made. Bacteria Growth Check is also ideal for classroom lessons and discussions.Number of Tests: 30 individual foilsSensitivity: Growth detection of festidious micro-organisms at <102, >102, >104, >106, >109Total Test Time: 48 Hours
