Overview
The Cole-Parmer 74905-20 is a high-precision, microprocessor-controlled syringe pump engineered for reproducible, low-volume fluid delivery in analytical, environmental, and isotopic applications. It operates on the principle of linear motor-driven plunger displacement within precision-machined syringes—enabling accurate volumetric metering without pulsation or backflow. Unlike peristaltic or diaphragm pumps, this syringe-based architecture eliminates tubing wear, fluid shear, and compressibility errors, making it ideal for ultra-trace analysis where sample integrity, minimal carryover, and nanoliter-level dosing are critical. Designed for integration into automated workflows—including ICP-MS sample introduction, LC pre-concentration, and online isotope ratio monitoring—the 74905-20 supports both standalone operation and networked control across heterogeneous lab environments.
Key Features
- Wi-Fi-enabled remote operation via native iOS and Android applications—no physical proximity required; compatible with standard 802.11 b/g/n networks
- Dual-control architecture: full functional access via Windows-based network control software (RDP-compatible) or mobile app (Lite version for monitoring only; Pro version for complete command execution)
- High-force linear actuation (>45 kg) ensures stable delivery across viscous or high-backpressure applications, including direct injection into capillary columns or microfluidic manifolds
- Interchangeable syringe compatibility: accepts fused silica (quartz) and PFA syringes from 0.3 mL to 10 mL—optimized for chemical inertness (e.g., HF resistance with PFA) and UV transparency (quartz for spectroscopic coupling)
- Calibration traceability: factory-calibrated flow profiles stored per syringe type; user-adjustable calibration offsets support GLP-compliant revalidation
- USB 2.0 and Ethernet interfaces provide redundant connectivity options for lab network integration and firmware updates
Sample Compatibility & Compliance
The 74905-20 accommodates chemically aggressive, volatile, or light-sensitive samples through its optional quartz and PFA syringe modules. Quartz syringes minimize adsorption and enable UV-Vis detection inline, while PFA variants withstand concentrated acids (including hydrofluoric acid), bases, and organic solvents—meeting ASTM D7260 and ISO 8573-1 purity requirements for trace metal analysis. The system complies with IEC 61000-6-3 (EMC) and IEC 61010-1 (safety) standards. When operated under validated SOPs with audit-trail-enabled software, it supports 21 CFR Part 11 compliance for electronic records and signatures in regulated laboratories.
Software & Data Management
The bundled Windows network control software provides real-time parameter visualization (flow rate, direction, elapsed time, remaining volume), programmable multi-step protocols (e.g., gradient elution, timed injections), and CSV export of operational logs. All commands—including start/stop, pause/resume, speed ramping, and valve switching—are timestamped and logged with operator ID fields. Mobile app telemetry includes battery status, connection health, and error code reporting. Firmware updates preserve configuration settings and maintain backward compatibility with legacy RDP deployments on Windows XP through Windows 10 LTSB systems.
Applications
- Isotope ratio mass spectrometry (IRMS) sample introduction with sub-microliter precision and zero memory effect
- Online pre-concentration systems for trace metals in petroleum or lubricant analysis (ASTM D5185, D6728)
- Low-flow microdialysis sampling in neurochemical monitoring
- Automated calibration standard delivery for ICP-OES and ICP-MS
- Controlled reagent addition in kinetic studies requiring millisecond-level timing resolution
- Integration with autosamplers and switching valves for unattended multi-sample processing
FAQ
Which operating systems support the network control software?
Windows XP SP3, Vista, Windows 7, and Windows 10 LTSB editions are officially supported. No macOS or Linux native client is available; remote desktop access is required for non-Windows environments.
Can multiple 74905-20 units be controlled simultaneously from one device?
Yes—the network software supports up to 16 independently addressable pumps on the same subnet, each configurable with unique IP and port assignments.
Are syringe calibration certificates included with purchase?
Factory calibration data is embedded in firmware and provided as a PDF report. NIST-traceable calibration certificates are available upon request at additional cost.
What safety features prevent over-pressurization or syringe breakage?
The pump continuously monitors motor current draw and halts operation if torque exceeds preset thresholds. Mechanical end-stop limits prevent plunger overtravel beyond syringe stroke capacity.
Is the iOS/Android app available outside the U.S. App Store?
Yes—the application is distributed globally via Apple App Store and Google Play Store, with localized language support for English, German, French, Japanese, and Simplified Chinese.
