| Product Name | Immunoassay Analyzer Cuvette Wash Solution, Alkaline Concentrate |
| Catalog No. | ATRCS-0022 |
| Description | A highly alkaline wash concentrate designed for automated chemiluminescence and electrochemiluminescence immunoassay analyzer cuvette washing stations. This formulation effectively removes protein-bound conjugates, luminol residues, and signal reagent carryover from reaction cuvettes and fluidic pathways, maintaining low background signal and assay precision. |
| Intended Use | Cuvette washing in automated CLIA and ECLIA immunoassay analyzers; removes residual chemiluminescent substrates, enzyme conjugates, and proteinaceous sample matrix components. |
| Principle / Technology | Alkaline hydrolysis of protein deposits combined with chelation of divalent cations and surfactant dispersion of hydrophobic residues |
| Detection Method | Dilute 1:10 with deionized water; load onto instrument wash station reservoir; instrument performs automated wash cycles per manufacturer protocol |
| Components / Formulation | Sodium hydroxide (0.5 N), potassium hydroxide (0.1 N), EDTA tetrasodium salt, non-ionic surfactant blend, deionized water |
| Storage Conditions | Store at 15–30 °C in original tightly closed container; avoid contact with acids and carbon dioxide |
| Shelf Life | 18 months from manufacture date; use diluted working solution within 7 days |
| Package Specifications | 1 L, 5 L, 10 L HDPE containers |
| Product Form | Clear colorless to pale yellow liquid concentrate |
| Key Features | High alkalinity ensures complete removal of chemiluminescent signal residues; chelating agents prevent calcium and magnesium soap formation; low-foam surfactants for automated liquid handling; validated on Roche Elecsys, Abbott Architect iSeries, Siemens Atellica, Beckman Access, and Mindray CL-series platforms |
| Purity | Sodium hydroxide 0.50 ± 0.02 N; EDTA 2.0 ± 0.1% (w/w) |
| Concentration | 10× concentrate; dilute to 1× with deionized water before 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 >13.0 (concentrate); pH 12.5–13.0 (working solution at 25 °C) |
| Shipping Conditions | Ambient temperature; corrosive liquid classification; ship as UN 1824, Class 8 |
| Expiration Date / Stability | 18 months concentrate; 7 days working solution; avoid exposure to atmospheric CO2 which forms carbonate precipitate |
| Regulatory / Compliance | CE-IVD marked; UN 1824 corrosive liquid classification for transport; manufactured under ISO 13485 quality system; compliant with EU IVDR 2017/746 |
| Compatibility | Compatible with polystyrene, acrylic, polypropylene, and quartz cuvettes; avoid prolonged contact with glass which may etch at this alkalinity; not compatible with polycarbonate |
| Recommended Buffer System | Use undiluted or dilute per instrument manufacturer specification |
| Application Notes / Precautions | Prepare working solution fresh weekly. Monitor background signal after cuvette wash cycles; increasing background may indicate need for more frequent cuvette wash or replacement. For instruments with separate aspiration and dispense wash stations, verify both stations receive fresh working solution. |
| Batch-to-Batch Consistency | pH and conductivity within ±5% of reference lot; cleaning efficacy validated |
