Plasma (VH2O2) Helix Test Indicator Strips (Refill)

Designed for insertion into cannulated challenge devices used in hydrogen peroxide (gas plasma) sterilizers, Plasma Helix Test Indicator Strips (Refills / Device-Free) are replacement indicator strips engineered specifically to align with the unique chemical kinetics of plasma sterilization. Because plasma processes rely on reaction chemistries fundamentally distinct from steam, these indicators feature specialized chemical formulations engineered to react and yield an unambiguous, definitive color change exclusively upon exposure to vaporized hydrogen peroxide ($VH_2O_2$). They offer an ideal, cost-effective, and dependable consumable solution for active sterile processing facilities seeking to replenish their test strip inventories while utilizing existing PCD hardware.
