Overview
The CoMetro CP-M305 Catalyst Reaction System Metering Pump is a high-precision, electronically controlled positive displacement pump engineered for demanding catalytic reaction workflows in research laboratories and pilot-scale chemical synthesis environments. It operates on a dual-servo motor-driven syringe-pump architecture combined with non-contact pressure sensing and real-time electronic flow compensation—enabling pulseless, continuous delivery across its full flow range of 0.001–5 mL/min. Unlike conventional peristaltic or diaphragm metering pumps, the CP-M305 employs a low-volume, high-rigidity fluid path with optimized valve sequencing and energy-storage equalization to eliminate flow ripple and ensure volumetric reproducibility under variable backpressure conditions up to 6000 psi. Its design adheres to fundamental principles of laminar flow control and closed-loop feedback regulation, making it suitable for stoichiometric reagent dosing, catalyst precursor injection, and multi-stream co-feeding in heterogeneous/homogeneous catalysis studies.
Key Features
- Pulseless flow delivery enabled by integrated energy-storage equalizer and rapid-fill actuation algorithm
- Non-contact pressure transduction system providing real-time pressure monitoring with alarm thresholds for both maximum and minimum pressure limits
- Dual-mode control interface: intuitive front-panel keypad operation and RS232 digital communication for integration into automated reactor control systems
- Modular fluid path construction with chemically inert options—PEEK for aggressive organic solvents and 316 stainless steel for high-temperature, high-pressure aqueous or corrosive media
- Onboard bypass valve and self-cleaning module supporting routine maintenance and long-term operational stability without disassembly
- Compliance-ready architecture with audit-trail-capable firmware logging (compatible with GLP/GMP documentation requirements)
Sample Compatibility & Compliance
The CP-M305 accommodates a broad spectrum of liquid-phase reactants, including organometallic precursors, viscous catalyst slurries (up to 500 cP), and thermally sensitive ligand solutions. Its PEEK and 316 SS wetted materials meet USP Class VI biocompatibility standards, enabling use in pharmaceutical process development where extractables and leachables must be minimized. The pump’s pressure and flow monitoring capabilities support adherence to ASTM D3236 (standard test method for viscosity of hot-melt adhesives) and ISO 8503-2 (surface roughness assessment for coated substrates), particularly when used in conjunction with inline viscometers or FTIR flow cells. All firmware logs—including flow setpoint changes, pressure excursions, and alarm events—are timestamped and exportable via RS232, facilitating compliance with FDA 21 CFR Part 11 for electronic records and signatures in regulated environments.
Software & Data Management
The CP-M305 supports ASCII-based command protocols over RS232, allowing seamless integration with LabVIEW, MATLAB, or custom SCADA platforms for synchronized dosing in multi-pump reactor configurations. Internal memory retains up to 1,000 event logs with time stamps, operational status flags, and diagnostic codes—accessible via serial query or exported as CSV files. Firmware updates are performed through secure bootloader mode, preserving calibration constants and user-defined presets. Remote analog input (0–5 V or 4–20 mA) enables external PID loop coupling—for example, linking flow rate to reactor temperature or pH feedback signals. No proprietary software installation is required; configuration and monitoring can be achieved using standard terminal emulators or third-party automation middleware.
Applications
- Precise metering of homogeneous catalysts (e.g., Grubbs, Buchwald, or Noyori complexes) into continuous-flow microreactors
- Controlled addition of initiators or chain-transfer agents in polymerization kinetics studies
- Delivery of air-sensitive reagents via Schlenk-line-compatible fluid paths with optional inert-gas purging ports
- Calibration traceability in analytical chemistry labs requiring certified volumetric dispensing per ISO/IEC 17025
- Teaching laboratory modules on fluid dynamics, mass transfer, and reaction engineering fundamentals
FAQ
What is the maximum allowable backpressure for continuous operation?
The CP-M305 is rated for continuous operation at up to 6000 psi (414 bar) when equipped with the 316 stainless steel fluid path and appropriate seals.
Can the pump be operated in gradient or programmable flow modes?
Yes—via RS232 commands, users may define time-based flow profiles with up to 100 step segments, including ramp, hold, and linear sweep functions.
Is the CP-M305 compatible with solvent-resistant tubing for HPLC-grade mobile phases?
While primarily designed for rigid syringe-style pumping, optional PEEK capillary adapters allow direct connection to 1/16″ OD stainless steel or fused silica tubing used in analytical-scale systems.
How is calibration traceability maintained?
Each unit ships with a factory calibration certificate referencing NIST-traceable gravimetric flow verification at three points across the operating range (0.001, 0.5, and 5 mL/min).
Does the pump support fail-safe shutdown on pressure fault detection?
Yes—the firmware triggers immediate motor stop and visual/audible alert upon exceeding user-defined upper or lower pressure thresholds, with configurable hysteresis to prevent nuisance tripping.
