LaMotte 1161 Test Tube – Cyanuric Acid Test Tube with Black Dot Viewer and Cap

The LaMotte 1161 test tube is specifically designed for cyanuric acid testing using the black dot visual method. This high-clarity tube features a built-in black dot at the base to aid in determining CYA concentration by visually obscuring the dot when turbidity reaches a certain point. Used in combination with the LaMotte cyanuric acid reagent, this tube provides accurate and repeatable results for pool and spa water analysis.

Equipped with a secure-fit cap and marked with graduated fill lines, the 1161 tube is a reliable tool for pool professionals, technicians, and facility operators managing stabilizer (CYA) levels in the field or lab.
