SpotCheck Plus – Glucose & Lactose Residue Test


Self-contained quick test to check for the presence of glucose and lactose on a surface in a food environment, for HACCP controls.

Simply swab a countertop / surface of equipment, release the liquid and the reagent inside the tube will turn green if there is any glucose and / or lactose residue, indicating poor surface hygiene.

The more contamination present, the quicker the colour change and darker the colour green.

Immediate corrective action can be taken if the surface is not hygienically clean.
