| Product Name | Biochemistry Analyzer Acid Wash Solution, 5% Phosphoric Acid-Based |
| Catalog No. | ATRCS-0018 |
| Description | A phosphoric acid-based wash solution for removing inorganic scale deposits, calcium oxalate crystals, and mineral precipitates from biochemistry analyzer cuvettes, reagent probes, and fluid transfer lines. Formulated to dissolve deposits without attacking polycarbonate or quartz cuvette materials. |
| Intended Use | Periodic descaling and maintenance cleaning of automated clinical chemistry analyzer cuvette wash stations and fluidic pathways. |
| Principle / Technology | Controlled acid dissolution of mineral scale and inorganic precipitates at low pH |
| Detection Method | Ready-to-use; no dilution required; aspirate through instrument fluidics for 5–10 minute contact time per manufacturer protocol |
| Components / Formulation | Phosphoric acid (5% v/v), non-ionic wetting agent, corrosion inhibitor, deionized water |
| Storage Conditions | Store at 15–25 °C in original tightly closed container; avoid contact with strong bases |
| Shelf Life | 36 months from manufacture date |
| Package Specifications | 500 mL, 2.5 L HDPE bottles |
| Product Form | Clear colorless liquid |
| Key Features | Optimized for polycarbonate cuvette safety; contains corrosion inhibitor for stainless steel components; phosphate-free alternative available for instruments with phosphate sensitivity; validated on Roche Cobas, Abbott Architect, Siemens ADVIA, and Beckman AU series analyzers |
| Purity | Phosphoric acid 5.0 ± 0.2% (w/v); meets ACS reagent specifications |
| Concentration | As specified (concentrate or ready-to-use) |
| Activity / Unit Definition | Cleaning efficacy validated by instrument carryover testing |
| Molecular Weight | Not applicable — detergent/surfactant formulations |
| Source / Origin | Synthetic detergent and surfactant components |
| pH Range / Optimal pH | pH 1.5–2.0 (neat solution at 25 °C) |
| Shipping Conditions | Ambient temperature; no special handling required |
| Expiration Date / Stability | 36 months under recommended storage; avoid prolonged contact with atmospheric CO2 which may cause buffer shift |
| Regulatory / Compliance | CE-IVD marked; manufactured under ISO 13485; compliant with EU IVDR 2017/746 for instrument maintenance reagents |
| Compatibility | Safe for polycarbonate, quartz glass, stainless steel 316L, PEEK, PTFE, and ETFE; avoid prolonged contact with aluminum, zinc, or galvanized surfaces |
| Recommended Buffer System | Use undiluted or dilute per instrument manufacturer specification |
| Application Notes / Precautions | Run instrument manufacturer's recommended acid wash cycle. After acid wash, perform minimum 3 rinse cycles with deionized water. Verify pH neutrality of final rinse waste before resuming patient testing. Recommend weekly preventive acid wash for high-throughput analyzers. |
| Batch-to-Batch Consistency | pH and conductivity within ±5% of reference lot; cleaning efficacy validated |
