PRO-Clean is the easiest and most accurate way to verify the cleanliness of food equipment surfaces. Simply swab a surface and release the reagent. If protein residue is present, the reagent will turn purple - the more contamination, the quicker the color changes and the darker it becomes. PRO-Clean instantly validates surface hygiene, allowing immediate corrective action to be taken when necessary. Results in 1-10 minutes depending on sensitivity required - Instant results allow for immediate corrective action All-in-one cost effective device- no instrumentation required Quick and easy way to monitor HACCP/SSOP program Easy-to-interpret color change - No training required Pass Caution Fail Fail Specifications: Time Sensitivity 1 minute 80 µg 5 minutes 50 µg 10 minutes 20 µg Patented Snap-Valve™ technology - snap & squeeze with pre-moistened swab bud Write-on swab tube label Shelf life: 18 months at room or refrigerated temperatures (2 - 25°C). Why test for protein residue? Protein is more difficult to remove from surfaces than glucose or other residues, so it's a good indicator for surface contamination. If you need to verify protein removal quickly, PRO-Clean is reliable and accurate. Literature Available:PRO-Clean DatasheetPRO-Clean ManualPRO-Clean Safety Data Sheet
