| Separation method | Swing-bucket or fixed-angle centrifugation, pressure-assisted expression, membrane filtration or continuous apheresis. | The method affects component yield, residual leukocytes, hemolysis risk, operating complexity and consumable selection. | Operating principle, validated process parameters, compatibility list and performance test results. |
| Processing capacity | Capacity should be stated as donations or procedures per hour, including loading, unloading, cleaning and quality checks. | Nominal cycle capacity can overstate real production if downtime and manual handling are excluded. | Factory acceptance test, throughput definition, cycle-time data and recommended staffing. |
| Component temperature control | Common storage practices include red cells at 1–6 °C, platelets at 20–24 °C with agitation, and frozen plasma at temperatures defined by local regulation, often at or below −18 °C. | Temperature exposure can affect component quality, shelf life and regulatory release. | Temperature limits, monitoring method, alarm thresholds, calibration records and applicable validation reports. |
| Closed-system compatibility | The equipment should support the intended sterile blood-bag configuration, tubing dimensions, connectors and transfer pathway. | Maintaining a closed or functionally closed system reduces contamination and handling risks. | Consumable compatibility matrix, sterile-path description, connector specifications and validation results. |
| Quality management | ISO 13485 is the principal international quality-management framework commonly requested for medical-device manufacturers. | A controlled quality system supports design control, complaint handling, corrective action and traceability. | Current certificate, certification scope, audit status and manufacturing-site details. |
| Risk management | ISO 14971-based risk management is widely used for identifying and controlling device-related hazards. | Risks may include electrical hazards, incorrect component routing, contamination, excessive pressure and software failure. | Risk-management summary, hazard controls, alarm verification and usability-engineering records. |
| Electrical and software safety | Electrical medical equipment commonly requires assessment against IEC 60601-1 and applicable collateral or particular standards. | Safety controls are essential for equipment used near donors, patients, blood products and fluid pathways. | Electrical safety reports, software lifecycle documentation, cybersecurity controls and alarm test records. |
| Consumable standardization | Blood-collection containers and accessories should comply with applicable national or international requirements, such as ISO 3826 where relevant. | Consumable availability and interchangeability directly affect operating continuity and total cost. | Material specifications, shelf-life data, sterilization method, lot traceability and supply agreement. |
| Service and spare parts | Review response time, preventive-maintenance interval, critical spare-parts list and local service capability. | Downtime can interrupt blood-component production and increase the risk of product loss. | Service-level agreement, escalation process, training plan, warranty terms and spare-parts pricing. |
| Regulatory pathway | Market access requirements differ by jurisdiction and may include device registration, conformity assessment, import authorization and post-market surveillance. | A certificate from one market does not automatically authorize sale or use in another market. | Declaration or certificate of conformity, registration status, labeling, instructions for use and vigilance procedure. |
