Overview
The Masterflex® C/L Series Peristaltic Pump Model 77122-00 is a precision-engineered, single-channel peristaltic pump designed for reliable, contamination-free fluid transfer in laboratory, pilot-scale, and light industrial applications. Operating on the principle of positive displacement via sequential compression of elastomeric tubing by rotating rollers, this pump eliminates fluid contact with internal mechanical components—ensuring sample integrity, ease of cleaning, and compliance with hygienic handling requirements. Its integrated motor-pump head architecture, constructed from corrosion-resistant 304 stainless steel and high-performance polyphenylene sulfide (PPS), delivers mechanical stability and long-term dimensional consistency under continuous operation. The unit is certified to UL, CSA, GS, and CE standards and rated IP22 for protection against vertically falling solids and limited ingress of moisture—making it suitable for controlled laboratory environments where electrical safety and operational reliability are paramount.
Key Features
- Manual analog speed control via calibrated thumbwheel (13–80 rpm), with momentary MAX button for transient full-speed operation
- Reversible DC motor enabling bidirectional flow—critical for priming, backflushing, and post-run tubing cleaning
- Integrated remote control interface (dry-contact compatible) on rear panel for integration into automated systems or centralized lab controls
- Robust PPS housing and 304 stainless steel pump head engineered for chemical resistance and thermal stability across ambient operating temperatures (5–40 °C)
- No display or digital electronics—minimizing electromagnetic interference (EMI) and enhancing suitability for sensitive analytical environments (e.g., near mass spectrometers or NMR units)
- Compliance-ready design: Supports audit-trail-capable process documentation when paired with external PLCs or SCADA systems meeting FDA 21 CFR Part 11 requirements
Sample Compatibility & Compliance
The C/L Series accommodates a broad spectrum of chemically compatible tubing materials—including Tygon® LFL (low-permeability, extended-life), Pharmed® BPT (USP Class VI, FDA-compliant), platinum-cured silicone, C-Flex®, and Viton®—enabling validated use across pharmaceutical manufacturing (GMP), food-grade processing (FDA 21 CFR 177), and aggressive chemical handling (e.g., dilute acids/bases, chlorinated solvents). Tubing selection directly governs flow rate linearity, pulsation profile, and service life: Pharmed tubing demonstrates >12 months service life at 50 rpm with water under ambient conditions; Viton provides optimal resistance to halogenated hydrocarbons and aromatic solvents. All configurations meet ISO 8573-1 (compressed air purity) compatibility benchmarks when used with clean, oil-free gas sources for pneumatic actuation interfaces.
Software & Data Management
While the 77122-00 operates as a standalone analog device without embedded firmware or USB connectivity, its remote control interface enables seamless integration with third-party data acquisition systems (e.g., LabVIEW, MATLAB, or custom PLC logic). Dry-contact inputs support start/stop commands and direction toggling, while optional external tachometer outputs (via add-on sensor kits) permit real-time RPM verification and closed-loop speed validation. When deployed within GLP/GMP workflows, pump operation logs—including runtime, direction cycles, and manual speed adjustments—can be captured externally and linked to electronic batch records (EBRs) in accordance with Annex 11 and ALCOA+ data integrity principles.
Applications
- Continuous reagent delivery in HPLC mobile phase preparation and autosampler feed lines
- Accurate dosing of cell culture media, buffers, or enzyme solutions in bioprocessing labs
- Controlled perfusion in organ-on-chip and microfluidic assay platforms
- Low-shear transfer of shear-sensitive biological suspensions (e.g., platelets, stem cells)
- Chemical feed in small-scale electrochemical reactors and corrosion testing cells
- Calibration fluid circulation in viscosity and density meter validation protocols (ASTM D1298, ISO 12185)
FAQ
Is the pump suitable for sterile applications?
Yes—when used with gamma-sterilizable tubing (e.g., Pharmed BPT or platinum-cured silicone) and installed in laminar flow hoods or isolators, the C/L Series supports aseptic fluid transfer under ISO 14644-1 Class 5 conditions.
Can flow rate be calibrated traceably?
Flow accuracy is tubing-dependent and must be verified gravimetrically per ISO 8655-3 using certified balance and temperature-controlled water. Masterflex provides nominal flow tables; users are required to perform in-house calibration for regulatory submissions.
What maintenance intervals are recommended?
Roller alignment and tubing compression force should be verified quarterly per Masterflex Technical Bulletin TB-104. No lubrication is required; periodic visual inspection of tubing fatigue and roller surface wear is advised.
Does the pump support analog speed modulation (0–10 V or 4–20 mA)?
No—the 77122-00 features only manual thumbwheel control and dry-contact remote switching. For analog input capability, consider the Masterflex I/P Series (e.g., Model 77400-10) with integrated 0–10 V interface.
Is the unit compliant with European RoHS and REACH directives?
Yes—all materials of construction comply with Directive 2011/65/EU (RoHS2) and Regulation (EC) No. 1907/2006 (REACH), with full SVHC declarations available upon request from Cole-Parmer’s regulatory team.
