McKesson OPA/28 High Level Disinfectant β 1 Gallon RTU
McKesson OPA/28 High-Level Disinfectant Solution (1 Gallon)
Ready-to-Use 0.575% Ortho-Phthalaldehyde Formula, Extended 28-Day Reuse Reuse Life, 10-Minute Manual Disinfection, 5-Minute AER Automated Reprocessing, Corrosion Inhibitors, and 100% Latex-Free
Ensuring rigorous high-level disinfection of semi-critical medical devices and endoscopes requires a trusted, fast-acting chemical sterilant. McKesson OPA/28 High Level Disinfectant is a ready-to-use, 0.575% buffered ortho-Phthalaldehyde (OPA) solution engineered for fast, reliable reprocessing of heat-sensitive instruments across clinical environments.
Formulated without requiring mixing or activation, OPA/28 provides an extended 28-day reuse lifecycle in soaking trays while maintaining efficacy. It delivers rapid 10-minute manual disinfection at room temperature (68Β°F / 20Β°C) and accelerates to a 5-minute contact cycle at 77Β°F (25Β°C) in Automated Endoscope Reprocessors (AER). Enhanced with buffering agents and corrosion inhibitors, it protects valuable flexible and rigid scopes from surface degradation, supplied in a 1-gallon jug.
Key Performance Features & Benefit Highlights
- Ready-to-Use OPA Formula: Pre-mixed 0.575% ortho-Phthalaldehyde formulation eliminates mixing errors and activation wait times.
- Extended 28-Day Reuse Life: Long-life solution remains effective in reuse basins for up to 28 days when monitored with OPA test strips.
- Fast Manual Disinfection (10 Mins): Achieves high-level disinfection in just 10 minutes at room temperature (68Β°F / 20Β°C) for manual soaking.
- AER System Compatibility (5 Mins): Compatible with Automated Endoscope Reprocessors, delivering high-level disinfection in 5 minutes at 77Β°F (25Β°C).
- Corrosion Protection & Surfactants: Contains buffering agents and corrosion inhibitors to safeguard delicate metals and scope components.
- Broad Device Compatibility: Safe for flexible endoscopes, rigid endoscopes, and heat-sensitive surgical instruments.
Infection Control Insight: High-level disinfectants like OPA/28 must be routinely tested before each reprocessing cycle using dedicated OPA Minimum Effective Concentration (MEC) test strips. This verifies that the active 0.575% ortho-Phthalaldehyde concentration remains above effective threshold limits throughout its 28-day reuse window.

Frequently Asked Questions
Q: Does McKesson OPA/28 require an activator before use?
A: No. OPA/28 is a ready-to-use formula that requires no mixing or activating chemicals prior to pouring into soaking trays or reprocessors.
Q: How do I know if the solution is still effective during the 28-day reuse window?
A: Test the solution prior to each use using McKesson OPA Test Strips to verify that the active ortho-Phthalaldehyde concentration remains above the minimum effective concentration (MEC).
Q: Are there any procedure contraindications for OPA solutions?
A: Yes. OPA solutions are generally contraindicated for urological instrumentation used in patients with a history of bladder cancer. Always consult full product labeling prior to use.
