Overview
The Masterflex® L/S Easy-Load Peristaltic Pump Head Model 07514-10 is an engineered solution for precise, repeatable, and low-maintenance fluid handling in regulated laboratory, biopharmaceutical, clinical diagnostics, and light industrial environments. Based on the well-established L/S (Larger-Scale) platform, this pump head utilizes peristaltic displacement—where rollers compress elastomeric tubing against a curved occlusion bed—to deliver pulse-dampened, non-invasive flow without fluid contact with mechanical components. Its design prioritizes operational reliability under continuous duty cycles, minimal tubing fatigue, and rapid, tool-free tubing loading—critical for applications requiring frequent tubing changes, sterile processing, or multi-channel parallelization.
Key Features
- Four-roller geometry ensures uniform compression distribution, minimizing flow pulsation and enhancing pressure stability across the full speed range (0.02–600 rpm).
- Optimized occlusion bed profile reduces localized stress on tubing walls, extending service life of L/S-series precision and high-performance tubing by up to 30% compared to legacy designs.
- Fixed-occlusion architecture supports eight standard L/S tubing sizes (L/S 13, 14, 16, 17, 18, 25, 15, 24) without mechanical adjustment—enabling rapid reconfiguration for varying flow rate or chemical compatibility requirements.
- Compact footprint (122 mm × 95 mm × 80 mm) facilitates integration into space-constrained enclosures, automated workstations, or portable diagnostic devices.
- Stackable configuration allows up to four pump heads to be mechanically and electrically synchronized on a single drive, supporting multi-stream dispensing, gradient generation, or redundant flow paths.
- ATEX Zone 2–certified variants (e.g., model 07514-30) are available for use in potentially explosive atmospheres encountered in solvent-handling or fermentation control systems.
Sample Compatibility & Compliance
The 07514-10 pump head is compatible exclusively with Masterflex L/S-series silicone and thermoplastic elastomer (TPE) tubing, including USP Class VI–compliant and FDA-listed formulations. It supports tubing inner diameters from 0.76 mm (L/S 13) to 3.2 mm (L/S 24), delivering calibrated flow rates ranging from 36 ml/min (L/S 13 at 600 rpm) to 2300 ml/min (L/S 18 at 600 rpm). All configurations meet ISO 8573-1 for compressed air purity when used with pneumatic drives, and support GLP/GMP workflows through traceable calibration documentation and optional analog/digital I/O for audit trail integration. The polypropylene housing and stainless-steel rollers comply with ASTM D520–22 for polymer chemical resistance and ISO 13485–2016 material biocompatibility requirements.
Software & Data Management
While the 07514-10 is a standalone pump head requiring external drive control, it is fully interoperable with Masterflex’s I/P and E/P series programmable drivers equipped with RS-485, USB, or 0–10 V analog interfaces. When paired with Masterflex FlowPro™ software (v3.2+), users can configure ramp profiles, set flow accuracy tolerances (±1.5% typical), log real-time rpm and estimated volumetric output, and export timestamped CSV reports compliant with FDA 21 CFR Part 11 for electronic record integrity. Audit trails include operator ID, parameter changes, and runtime duration—supporting routine validation and periodic review per ICH Q7 Annex 19.
Applications
- Bioreactor feed and harvest lines requiring gentle shear-sensitive cell suspension transfer.
- In-line sampling loops for HPLC and LC-MS systems where contamination-free, low-dead-volume fluid routing is essential.
- Automated reagent dispensing in clinical analyzers and ELISA platforms.
- Continuous diafiltration and buffer exchange in downstream purification skids.
- Environmental monitoring systems pumping corrosive or particulate-laden aqueous samples from remote probes.
- Pharmaceutical clean-in-place (CIP) and sterilize-in-place (SIP) circulation loops using steam-compatible TPE tubing.
FAQ
What tubing sizes are supported by the 07514-10 pump head?
It accommodates eight L/S-series tubing sizes: L/S 13, 14, 16, 17, 18, 25, 15, and 24—each pre-calibrated for flow accuracy at 600 rpm.
Is tubing replacement possible without tools?
Yes—the Easy-Load mechanism enables full tubing insertion and seating in under 15 seconds with no wrenches, clamps, or alignment fixtures required.
Can multiple 07514-10 heads operate synchronously?
Up to four units may be stacked and driven in phase via a single Masterflex E/P Series drive with multi-head expansion module.
Does this pump head meet regulatory requirements for pharmaceutical manufacturing?
When used with USP Class VI tubing and validated drive firmware, it supports GMP-compliant operations; full validation packages—including IQ/OQ templates—are available upon request.
What is the maximum continuous inlet pressure rating?
2.7 bar (40 psi) for L/S 13, 16, 17, and 15 tubing; pressure ratings decrease with larger IDs per ISO 8031:2017 Annex B guidelines.
