Overview
The HL-6B is an industrial-grade single-channel peristaltic pump engineered for continuous, high-flow fluid transfer in demanding laboratory and pilot-scale process environments. Operating on the principle of positive displacement via roller compression of flexible tubing, it delivers precise, pulse-free flow without exposing internal components to the pumped medium—ensuring contamination-free operation and eliminating the need for valves or seals. Unlike centrifugal or diaphragm pumps, the HL-6B maintains consistent volumetric delivery independent of fluid viscosity (within operational limits), making it ideal for shear-sensitive biological solutions, aggressive solvents, slurries, and abrasive suspensions. Its robust aluminum alloy chassis and reinforced gearmotor assembly support extended duty cycles under sustained load, while the digital LED speed display enables real-time monitoring and repeatable setpoint recall—a critical requirement for GLP-compliant workflows and method reproducibility.
Key Features
- Wide adjustable speed range supporting flow rates from 2,000 to 150,000 mL/h—optimized for both low-volume precision dosing and bulk transfer applications
- Digital LED speed display with non-volatile memory function, retaining last-used RPM setting after power cycling
- Industrial-grade motor and precision-machined pump head designed for >10,000 hours of continuous operation under rated load
- High back-pressure capability (≥2 kg/cm²) enabled by dual-roller compression geometry and reinforced tubing retention mechanism
- Modular pump head compatible with standard peristaltic tubing sizes (ID 3.2–12.7 mm), facilitating rapid tube replacement and cross-platform tubing validation
- Front-panel rotary speed control with tactile feedback and fine-resolution adjustment (1 rpm increments within operational range)
- EMC-compliant design meeting IEC 61326-1 for electromagnetic compatibility in shared laboratory instrumentation environments
Sample Compatibility & Compliance
The HL-6B accommodates a broad spectrum of fluid types—including aqueous buffers, organic solvents (e.g., acetone, IPA, THF), cell culture media, fermentation broths, and particulate-laden process streams—provided tubing material compatibility is verified (e.g., silicone, Viton®, Tygon® LFL, or PharMed® BPT). It complies with general safety requirements per IEC 61010-1 for electrical equipment used in laboratory settings. While not certified for hazardous area use (ATEX/IECEx), its sealed electronics and drip-proof front panel meet IP20 ingress protection standards. The pump supports audit-ready documentation practices through manual logbook integration and is routinely deployed in facilities operating under ISO/IEC 17025, FDA 21 CFR Part 11 (when paired with validated data capture systems), and cGMP-aligned process protocols.
Software & Data Management
The HL-6B operates as a standalone analog-controlled instrument with no embedded firmware or digital communication interface (e.g., RS-232, USB, or Modbus). All operational parameters are configured manually via front-panel controls; no software installation or driver dependency is required. For traceable operation, users may integrate the pump into external SCADA or LabVIEW-based monitoring systems using optional analog 0–10 V or 4–20 mA speed output modules (sold separately). Flow calibration certificates and tubing performance data sheets are available upon request to support IQ/OQ validation activities. Raw speed settings and runtime logs must be recorded manually or via external time-stamped video documentation to satisfy GLP record-keeping expectations.
Applications
- Continuous feed in bioreactor and fermenter systems requiring stable nutrient or antifoam addition
- High-throughput media preparation and sterile filtration line priming in cell therapy manufacturing
- Recirculation loops in electrochemical flow cells and membrane separation testing rigs
- Automated sample introduction in ICP-OES and HPLC autosampler auxiliary manifolds
- Process-scale solvent recovery and waste stream transfer in chemical synthesis labs
- Calibration fluid delivery in flow meter verification benches per ISO 4064-2
FAQ
What tubing sizes are compatible with the HL-6B pump head?
Standard tubing inner diameters ranging from 3.2 mm to 12.7 mm are supported; recommended wall thickness is 1.6 mm for optimal compression life and flow consistency.
Can the HL-6B be operated continuously for 24/7 applications?
Yes—its thermal management system and brushless DC motor architecture are rated for uninterrupted operation at ≤80% of maximum speed under ambient temperatures up to 40°C.
Is the HL-6B suitable for sterile or cleanroom environments?
The unit itself is not ISO Class 5-certified, but when paired with autoclavable or gamma-sterilizable tubing and installed in laminar flow hoods or isolators, it meets common aseptic processing requirements.
Does the HL-6B include flow calibration or accuracy certification?
Factory calibration is performed at three points across the speed range (low/mid/high); NIST-traceable flow verification reports are available as an add-on service.
How is maintenance performed on the HL-6B?
Routine maintenance consists of periodic roller lubrication (every 6 months), tubing replacement based on compression fatigue (typically 100–500 hours depending on speed and tubing type), and visual inspection of motor coupling integrity.
