The Helix PCD Test (Process Challenge Device) is a reliable daily test for Class B bench-top sterilizers and pre-vacuum hospital steam sterilizers, designed to evaluate steam penetration and detection of inert gases. Compatible with multiple sterilization processes including Steam, EO (Ethylene Oxide), and H₂O₂ (Hydrogen Peroxide), this test uses color-changing, water-based, non-toxic chemical indicators for easy interpretation. It complies with ISO 11140-1 standards and guarantees 250 cycles. The self-adhesive design allows for secure placement and traceability documentation. An essential quality assurance tool for healthcare facilities sterilizing hollow instruments.
