McKesson OPA-28 Concentration Indicator Test Strips - Single Use Sterility Verification Pads (50 Strips/Bottle)

Professional-Grade OPA Concentration Verification System

Ensure optimal disinfection efficacy with our premium OPA-28 concentration indicator test strips, specifically engineered for healthcare facilities requiring precise minimum effective concentration (MEC) verification prior to each high-level disinfection cycle.

Clinical Performance Features

• Rapid 3-Second Dip Protocol: Streamlined testing procedure minimizes workflow interruption while maintaining laboratory-grade accuracy for busy clinical environments
• 90-Second Read Time: Fast, reliable results allow immediate verification of solution potency before instrument reprocessing begins
• Oversized Indicator Pad: Generously proportioned reactive surface area delivers bold, unmistakable color transitions that eliminate interpretation errors even in variable lighting conditions
• Integrated Color Comparison Chart: Each bottle features a permanently affixed, definitive color identification reference chart ensuring consistent, standardized readings across multiple users and shifts
• Extended Shelf Stability: Industry-leading 18-month unopened shelf life and 6-month post-opening viability maximize inventory efficiency and reduce waste in high-volume facilities
• Latex-Free Construction: Manufactured without natural rubber latex to protect sensitive patients and staff from potential allergic reactions

Why Healthcare Professionals Choose This Solution

Maintaining the minimum effective concentration of ortho-phthalaldehyde (OPA) solutions is critical for achieving high-level disinfection of heat-sensitive medical instruments. These test strips provide the verification checkpoint that infection prevention protocols demand, offering peace of mind that your reprocessing workflow meets or exceeds regulatory standards.

The large, easy-to-read indicator pad transforms from its baseline color to a distinct verification shade when exposed to properly concentrated OPA solution, giving reprocessing technicians immediate visual confirmation. This eliminates guesswork and documentation uncertainty, supporting your facility's commitment to patient safety and regulatory compliance.

Optimized for High-Volume Clinical Settings

Packaged in convenient 50-strip bottles with dual-bottle case options, this system is designed for departments processing multiple instrument loads daily. The definitive color chart remains permanently visible on each bottle, ensuring every team member—from seasoned sterile processing veterans to newly trained technicians—can perform accurate concentration verification without additional reference materials.
