Masterflex L/S Economy Integrated Peristaltic Pump Drive

Overview

The Masterflex L/S Economy Integrated Peristaltic Pump Drive (Model 07555-00) is a compact, cost-optimized benchtop peristaltic pump system engineered for reliable, pulse-free fluid transfer in routine laboratory, pilot-scale, and light industrial applications. Operating on the principle of positive displacement via roller compression of flexible tubing—known as peristalsis—the drive delivers consistent volumetric flow without fluid contact with internal mechanical components. This design eliminates contamination risk, prevents cross-sample carryover, and ensures compatibility with aggressive, shear-sensitive, or particulate-laden fluids. The unit integrates motor, speed control electronics, and front-panel interface into a single housing, eliminating external controllers and reducing footprint. Designed for long-term stability under continuous operation, it features a brushed DC motor with thermal protection and robust gear train architecture for high reproducibility across extended duty cycles.

Key Features

• Bi-directional brushed DC motor enables intuitive tube priming, backflushing, and cleaning without manual reorientation;
• Front-panel LED indicators provide real-time power status and operational feedback for rapid visual verification;
• Single-knob speed adjustment with coarse resolution (±5% accuracy) simplifies setup for non-critical flow applications;
• Dedicated power switch allows independent confirmation of speed setting prior to activation;
• DB9 rear-panel interface supports TTL-level remote start/stop control—compatible with PLCs, data loggers, or custom automation systems;
• Compact chassis (23 × 18.3 × 13.4 cm) and low mass (2.7 kg) facilitate integration into fume hoods, biosafety cabinets, or modular process skids;
• IP22-rated enclosure provides basic protection against vertically falling drips and solid objects ≥12.5 mm—suitable for controlled indoor lab environments;
• Universal AC input (90–130 VAC / 180–260 VAC, 50/60 Hz) with region-specific IEC 320 C13 cord supplied upon order confirmation.

Sample Compatibility & Compliance

This drive is compatible with twelve standard Masterflex L/S-series pump heads—including Easy-Load II, Easy-Load 3, multi-channel, high-efficiency, and cartridge-style configurations—but excludes PTFE-tubing and PTFE-diaphragm pump heads (not recommended for use with models 07555-00 or 07555-05 due to torque limitations). Tubing selection determines chemical resistance, pressure rating, and flow linearity; common options include C-Flex ULTRA (USP Class VI, FDA-compliant), PharMed BPT, and Norprene. While the drive itself does not carry CE, UKCA, or UL certification, its electrical architecture conforms to IEC 61000-6-3 (EMI emission) and IEC 61000-6-2 (immunity) standards when operated within specified voltage and ambient temperature ranges (10–40°C). For GLP/GMP workflows requiring audit trails, optional NIST-traceable calibration documentation (P/N 17050-01) is available to support instrument qualification protocols.

Software & Data Management

The 07555-00 operates as a standalone analog-controlled device and does not feature embedded firmware, USB connectivity, or proprietary software. All operational parameters are set manually via front-panel controls. Remote operation is limited to digital TTL-level start/stop signals via the DB9 interface—no analog speed modulation or feedback communication is supported. For automated data capture, users integrate the drive into third-party systems using external flow meters (e.g., Coriolis or ultrasonic sensors) paired with SCADA or LabVIEW-based acquisition platforms. Optional accessories—including handheld remote controller (P/N 07528-80) and footswitch (P/N 77595-35)—enable hands-free operation in sterile or ergonomically constrained settings without modifying core drive functionality.

Applications

• Media dispensing and buffer transfer in cell culture and microbiology labs;
• Continuous feed of reagents in titration, colorimetry, or spectrophotometric assays;
• Perfusion of bioreactors and hollow-fiber systems during process development;
• Low-pressure solvent delivery in preparative chromatography and extraction workflows;
• Recirculation loops for pH or conductivity probe calibration and maintenance;
• Controlled dosing of enzymes, antibodies, or viscous polymer solutions in QC testing;
• Integration into OEM analytical instruments where space, cost, and reliability are primary constraints.

FAQ

Which pump heads are certified for use with the 07555-00 drive?
Easy-Load II, Easy-Load 3, standard L/S, multi-channel, high-efficiency, and cartridge-style pump heads are fully supported. PTFE-tubing and PTFE-diaphragm pump heads are explicitly excluded due to insufficient torque output.
Can this drive be used in GMP-regulated environments?
Yes—when paired with validated tubing (e.g., USP Class VI-certified C-Flex ULTRA), documented calibration (P/N 17050-01), and appropriate change control records. However, it lacks 21 CFR Part 11-compliant electronic audit trail functionality.
What is the minimum programmable flow rate accuracy?
Speed control resolution is ±5% of setpoint; actual flow accuracy depends on tubing elasticity, occlusion consistency, and fluid viscosity—calibration at operating conditions is recommended for quantitative work.
Is there an option for analog speed modulation?
No—the 07555-00 accepts only digital TTL start/stop commands via DB9. Analog voltage or current input for variable speed control is not supported.
How is thermal management handled during extended operation?
The 37 W motor incorporates thermal cut-off protection and passive convection cooling. Continuous operation at >80% maximum speed is advised only with adequate airflow and ambient temperatures ≤35°C.
