Overview
The Masterflex® L/S® Standard Pump Head Model 07013-20 is a precision-engineered peristaltic pump head designed for repeatable, pulse-minimized fluid transfer in laboratory, analytical, and OEM integration applications. Based on the proven L/S platform architecture, this pump head operates via positive displacement through sequential compression of elastomeric tubing by rotating rollers—ensuring complete fluid isolation, zero contamination risk, and maintenance-free operation without valves or seals. Its compact, single-channel configuration features inlet and outlet ports aligned on the same side, enabling installation in space-constrained enclosures or multi-head arrays. The 07013-20 variant is specifically calibrated for L/S 13 tubing (1.6 mm ID), delivering a flow range of 0.057–1700 mL/min at speeds from 0.02 to 600 rpm, with a maximum system pressure rating of 2.7 bar. Constructed with a transparent polycarbonate housing and cold-rolled steel rotor, it balances cost efficiency with mechanical robustness and visual operational monitoring.
Key Features
- Precision-molded, single-tube-size design optimized for high accuracy and long-term repeatability (CV < ±1.5% under controlled conditions)
- Transparent polycarbonate housing enables real-time visual verification of tubing compression, roller engagement, and occlusion integrity
- Cold-rolled steel (CRS) rotor provides dimensional stability, consistent torque transmission, and extended service life under continuous operation
- Side-by-side inlet/outlet port layout minimizes footprint and simplifies manifold routing in benchtop or integrated systems
- Fixed-occlusion geometry ensures stable flow profile across speed ranges; no manual adjustment required during operation
- OEM-ready mechanical interface compatible with all Masterflex L/S series drivers (e.g., L/S Digital, L/S Analog, L/S Touch), supporting up to four pump heads per driver chassis
- Includes standard accessories: tubing installation key, single-channel mounting bracket, and one 38 cm length of Masterflex Norprene® L/S 13 tubing
Sample Compatibility & Compliance
The 07013-20 pump head is validated for use with Masterflex L/S 13 precision tubing (1.6 mm inner diameter), including Norprene®, PharMed® BPT, and Viton® formulations—each selected per chemical compatibility requirements (e.g., pH 1–14, organic solvents, oxidizing agents). It conforms to ISO 8536-4 (infusion equipment) dimensional tolerances for tubing seating and roller path geometry. While the pump head itself carries no intrinsic regulatory certification, its material composition (UL94 V-0 rated PC housing; RoHS-compliant CRS rotor) supports integration into systems compliant with IEC 61010-1 (safety of laboratory equipment) and FDA 21 CFR Part 11 when paired with audit-trail-capable drivers and software. No ATEX or IECEx certification is applicable to this model.
Software & Data Management
As a passive mechanical component, the 07013-20 pump head does not incorporate embedded electronics or firmware. All control, calibration, and data logging functions are managed externally via the host L/S driver unit. When operated with Masterflex L/S Digital or L/S Touch drivers, users access programmable speed profiles, run-time logging, and USB/RS-232 data export—enabling traceable operation within GLP/GMP workflows. Driver firmware supports configurable ramp rates, pause/resume sequences, and event-triggered data capture. Integration with third-party SCADA or LabVIEW environments is achieved through ASCII command protocols or Modbus RTU, facilitating automated batch documentation and electronic record retention per 21 CFR Part 11 requirements.
Applications
- Continuous reagent delivery in automated titrators, ion chromatography sample introduction, and spectrophotometric flow cells
- Media perfusion in cell culture bioreactors and organ-on-chip microfluidic platforms
- Calibration standard dispensing in clinical chemistry analyzers and environmental water quality monitors
- OEM integration into diagnostic instruments requiring low-shear, contamination-free fluid handling (e.g., hematology analyzers, PCR liquid handlers)
- Controlled dosing of aggressive or shear-sensitive fluids—including glycerol-water mixtures, polymer solutions, and enzyme-containing buffers—where sealless transport is mandatory
- Process validation studies requiring documented flow consistency over extended durations (≥1000 hours)
FAQ
What tubing sizes are compatible with the 07013-20 pump head?
Only L/S 13 tubing (1.6 mm inner diameter) is mechanically and hydraulically matched to this pump head’s roller geometry and occlusion depth.
Can this pump head be used with stainless steel rotors?
No—the 07013-20 designation specifies a cold-rolled steel rotor. For stainless steel (SS) compatibility, select model 07013-21 (PC housing + SS rotor) or 07013-52 (PPS housing + SS rotor).
Is the 07013-20 suitable for sterile or USP Class VI applications?
The pump head itself is not certified for sterility or USP Class VI; however, when paired with USP Class VI-compliant tubing (e.g., PharMed BPT) and validated cleaning procedures, it may be incorporated into aseptic processes.
How many pump heads can be mounted on a single L/S driver?
Up to four identical pump heads (e.g., four 07013-20 units) may be installed using optional multi-head mounting brackets (e.g., 07013-09 for quad configuration), subject to driver torque and power specifications.
Does this pump head require periodic recalibration?
No—flow accuracy is inherently determined by tubing dimensions, roller speed, and occlusion geometry. Calibration is performed at the driver level via speed-to-flow mapping using gravimetric or volumetric verification per ASTM D3417 or ISO 4787.
