Channelcheck tests for three common organic soils at once: blood, protein and carbohydrates with improved sensitivity of the carbohydrate and protein pads
The color and color change for the protein pad have changed to a white (negative) and to a blue/purple (positive), which enhances the visual interpretation of results
Capable of testing virtually any lumened instrument for residual organic soils, no matter the channel size
There are 50 tests in a bottle and two bottles in a box
