Overview
The Masterflex L/S Digital Process Peristaltic Pump Model 07575-10 is a precision-engineered, industrial-grade peristaltic pumping system designed for demanding laboratory, pilot-scale, and continuous process applications requiring high repeatability, chemical compatibility, and operational robustness. Based on the proven Cole-Parmer Masterflex L/S platform, this unit employs a brushless DC motor delivering smooth torque across its full 0.1–600 rpm speed range, with an accuracy of ±0.1% of setpoint — critical for volumetric dispensing, media transfer, and reagent delivery where flow consistency directly impacts assay integrity or process yield. Its peristaltic principle—where fluid is contained entirely within disposable tubing and moved via sequential compression by rotating rollers—ensures complete fluid isolation, eliminating cross-contamination risks and enabling safe handling of aggressive solvents, biological suspensions, viscous slurries, and sterile formulations. The pump’s architecture supports both single- and dual-head configurations, allowing scalable flow rates without compromising control fidelity or mechanical stability.
Key Features
- IP66- and NEMA 4X-rated enclosure constructed from electropolished 316 stainless steel, enabling direct washdown with water or disinfectants in regulated environments (e.g., cleanrooms, bioprocessing suites, QC labs).
- Sealed, membrane-style keypad with tactile feedback and programmable lock function to prevent accidental parameter changes during unattended operation.
- Backlit LCD display showing real-time metrics: rotational speed (rpm), calculated flow rate (mL/min), dispensed volume (user-selectable units: mL, L, or gal), cumulative total volume, repeat cycle count, and inter-dispense interval (programmable up to 99 h 59 min 59 s).
- Non-volatile memory stores calibrated flow coefficients for up to one tube size — retained after power cycling, ensuring long-term measurement traceability without recalibration.
- Bidirectional rotation capability facilitates pre- and post-run tubing purging, minimizing carryover and supporting inline cleaning-in-place (CIP) protocols.
- Analog input compatibility (0–20 mA, 4–20 mA, 0–10 V) enables seamless integration into PLC-controlled systems, SCADA networks, or automated reactor platforms.
- Modular head design supports stacking of two L/S pump heads on a single driver chassis — doubling throughput while maintaining synchronized speed and phase control.
Sample Compatibility & Compliance
The Model 07575-10 accommodates a broad spectrum of tubing materials and dimensions (Sizes 13–36), including Tygon® LFL (low extractables, USP Class VI), platinum-cured silicone (biocompatible, autoclavable), reinforced bio-platinum silicone (enhanced longevity under pulsatile load), and PTFE-lined or fully PTFE pump heads rated for concentrated acids, caustics, and halogenated organics. When paired with certified tubing, the system complies with FDA 21 CFR Part 11 requirements for electronic records when used with validated software interfaces. Its construction and certifications — ETL (UL 61010-1), CE (EN 61000-6-2/6-3, EN 61010-1), and ISO 9001:2000 — support deployment in GLP, GMP, and ISO 17025-accredited laboratories. The IP66 rating satisfies IEC 60529 requirements for dust-tight and high-pressure water jet resistance — essential for applications in pharmaceutical manufacturing or food safety testing where environmental hygiene is audited.
Software & Data Management
While the 07575-10 operates as a standalone instrument with embedded firmware, its analog I/O ports permit integration with third-party data acquisition systems (e.g., LabVIEW, MATLAB, DeltaV) for time-stamped flow logging, alarm triggering, and batch record generation. The internal memory retains calibration offsets and last-used parameters, supporting audit-ready configuration history. For regulatory workflows, optional remote control modules (e.g., footswitch 07575-84, hand switch 07575-82, or 7.3 m extension cable 07575-80) allow hands-free activation — reducing operator contact and enhancing contamination control. All firmware updates are performed via standard RS-232 or USB-to-serial adapters (not included), with version logs accessible through service mode for compliance documentation.
Applications
- Automated media preparation and buffer dispensing in cell culture and fermentation workflows.
- Continuous sampling and dilution in online HPLC or IC feed systems.
- Reagent metering in clinical analyzers and immunoassay platforms.
- Chemical dosing in wastewater treatment pilot studies or corrosion inhibition trials.
- Viscous polymer solution transfer in material science labs (e.g., hydrogel precursor delivery).
- Clean-in-place (CIP) and sterilize-in-place (SIP) circulation loops in single-use bioreactor skids.
- Multi-stream blending using Y-branch manifolds or multi-channel pump heads (2–32 channels available separately).
FAQ
What tubing sizes are supported, and how do I select the correct one for my application?
The driver accepts Masterflex L/S tubing sizes 13 through 36. Selection depends on required flow rate, pressure head, viscosity, and chemical compatibility — refer to the published flow vs. rpm curves for each size. High-pressure applications (>3 bar) require Size 35 or 36 with reinforced wall construction.
Can this pump be integrated into a validated GMP process?
Yes — when configured with documented calibration procedures, traceable tubing lots, and appropriate I/O logging, it meets foundational requirements for GMP Annex 11 and FDA guidance on equipment qualification (IQ/OQ/PQ).
Is firmware upgrade capability available, and how is it performed?
Firmware updates are delivered via serial interface using Cole-Parmer-provided utilities; version history and update timestamps are stored internally for audit review.
Does the dual-head configuration maintain synchronized flow between channels?
Yes — both pump heads are mechanically coupled to the same motor shaft, ensuring identical speed and phase alignment without drift, critical for ratio-based mixing or parallel sample processing.
What maintenance is required beyond routine tubing replacement?
No scheduled lubrication or bearing service is needed — the brushless motor and sealed roller assembly are designed for >10,000 hours MTBF. Annual verification of speed accuracy and tubing compression geometry is recommended for regulated use.
