Opal Test Strips – 90‑Second Readings for OPA Concentration

Opal Test Strips are designed to determine whether the concentration of Ortho-Phthalaldehyde (OPA), the active ingredient in OPAL, is at or above the Minimum Recommended Concentration (MRC) of 0.35%. Quick and straightforward, these strips deliver a reliable read in 90 seconds with a 3‑second dip time.

Easy to integrate into standard disinfection workflows, the kit includes two 50‑strip packs, providing a total of 100 tests per order. A color reference chart is included to confirm the concentration amount visually, helping staff make prompt, informed decisions.

• Package size and capacity: Includes two 50‑strip packs (2 x 50 strips) for a total of 100 tests per order, ideal for routine QC and ongoing monitoring.
• Dip time: 3‑second immersion is sufficient to initiate the test reaction quickly.
• Read time: Results appear in 90 seconds, enabling fast decision making in busy workflows.
• Concentration target: Designed to indicate whether OPA concentration is above or below the 0.35% MRC.
• Color reference chart: Visual comparator helps verify the exact concentration level against the standard threshold.
• Workflow compatibility: Specifically suited for use with OPAL‑based disinfection processes and related quality control procedures.
• Storage guidance: Store as recommended to maintain strip integrity and accuracy between tests.

These test strips support consistent monitoring of OPA concentrations, reducing uncertainty in disinfectant validation and fitting neatly into routine quality control procedures. By offering a simple, rapid read and a straightforward visual confirmation, they help maintenance of proper disinfection practices and regulatory compliance without adding complexity to your SOPs. The two‑pack configuration minimizes downtime between tests and keeps inventory aligned with daily QC needs.

Frequently Asked Questions

• What does 0.35% MRC mean for these test strips? The 0.35% MRC is the minimum concentration recommended for effective disinfection with OPAL. The strips indicate whether your OPA level is at or above this threshold.
• How long does it take to get a result? After a 3‑second dip, a color change is read and interpreted within 90 seconds using the included color reference chart.
• How should I store the Opal Test Strips? Store the strips according to the packaging guidelines to preserve accuracy, typically at controlled room temperatures and away from moisture or direct sunlight.
• Are these strips compatible with other OPAL products? They are designed for use within OPAL‑based disinfection workflows and should be used in accordance with your facility’s SOPs for disinfectant validation.
• What’s included in the package? The kit includes two 50‑strip packs (2 x 50 strips) and a color reference chart for concentration verification.
