| Channel configuration | Two syringe channels | Whether each channel can be started, stopped, and configured independently. |
| Flow-rate range | Model- and syringe-dependent; no single range applies to every pump. | Request the specified range for each supported syringe size, channel, and operating mode. |
| Flow accuracy and repeatability | Performance depends on the syringe, fluid, flow rate, and test conditions. | Ask for test results, stated tolerances, and the test method used for the quoted figures. |
| Syringe compatibility | Compatibility varies by pump model, syringe dimensions, and holder design. | Confirm supported syringe sizes and whether the supplier provides a compatibility list or adapter options. |
| Operating modes | Common options may include infusion and withdrawal; available modes are model-specific. | Check which modes are supported on both channels and whether settings can differ by channel. |
| Drive and syringe positioning | Motorized drive systems move the syringe plunger; mechanical design differs across models. | Review the drive mechanism, syringe retention, setup procedure, and suitability for the intended workload. |
| Alarms and status indicators | Alarm functions vary; potential conditions include occlusion, end of travel, or setup errors. | Request the alarm list, channel-specific behavior, and details on how alerts are displayed or sounded. |
| Controls and connectivity | User controls and communication interfaces are model-dependent. | Confirm display and control options, available interfaces, communication protocol, and software requirements. |
| Quality and compliance documents | Documentation depends on the product category and intended market. | Request applicable certificates, declarations, user manuals, and product-specific test records; verify their scope and validity. |
| Calibration and final testing | A documented inspection and performance-testing process supports consistent production quality. | Ask which checks are performed on each unit and whether a serial-number-linked test report is available. |
| Customization and OEM support | Options may include labeling, language, packaging, or configuration changes; availability varies. | Confirm minimum order quantities, engineering scope, sample approval, and change-control procedures. |
| Service and spare parts | Support terms and parts availability are supplier- and destination-dependent. | Clarify warranty coverage, repair process, technical support hours, and spare-parts lead times. |
| Manufacturing traceability | Traceability practices differ between production facilities. | Check whether units and critical components are identifiable through serial or lot records. |
