Overview
The HL-3A Split-Design Single-Channel Peristaltic Pump is a laboratory-grade constant-flow delivery system engineered for precision fluid handling in research, quality control, and process development environments. Operating on the peristaltic principle—where rollers compress flexible tubing to generate positive displacement—the HL-3A delivers pulse-free, contamination-free flow without exposing internal components to the fluid path. Its split architecture separates the motor-driven pump head from the digital controller unit, enabling flexible installation in fume hoods, biosafety cabinets, or integrated analytical workflows where spatial constraints or thermal isolation are critical. Designed for long-term stability under continuous operation, the HL-3A maintains volumetric accuracy across its full flow range (60–12,000 mL/h), making it suitable for applications requiring reproducible dosing, gradient elution support, or continuous perfusion in cell culture or environmental sampling systems.
Key Features
- Stepless electronic speed control (0–155 rpm) with real-time digital RPM readout on the front-panel LCD, ensuring precise rotational adjustment and traceable parameter logging.
- Robust split configuration: pump head (120 × 120 × 180 mm) mounts independently from the controller (260 × 200 × 120 mm), facilitating modular integration into custom rigs or OEM instrumentation.
- High-pressure capability (≥196 kPa / ≥2 kg/cm²) enables reliable operation with standard silicone or Tygon® tubing up to 6.4 mm ID, even under moderate backpressure from filters, columns, or narrow-bore transfer lines.
- Single-channel design optimized for unidirectional, non-invasive fluid transfer—ideal for shear-sensitive biological samples, reagents, buffers, or calibration standards where metal-contact pumps pose contamination or degradation risks.
- Thermally stable brushless DC motor with low-noise operation (<55 dB at 1 m), supporting extended unattended runs in quiet lab environments such as analytical labs or teaching facilities.
Sample Compatibility & Compliance
The HL-3A accommodates a wide range of chemically compatible tubing materials—including silicone, Viton®, Norprene®, and PharMed® BPT—enabling safe handling of aqueous solutions, organic solvents, mild acids/bases, and biological media. Tubing selection is user-configurable based on flow rate, chemical resistance, and compliance requirements (e.g., USP Class VI for pharmaceutical use). While the HL-3A itself is not certified to ISO 13485 or FDA 21 CFR Part 11, its design supports GLP-compliant workflows when paired with validated tubing, calibrated flow verification protocols, and operator-defined SOPs. It meets general electrical safety requirements per IEC 61010-1 for laboratory equipment and operates within CE-marked electromagnetic compatibility (EMC) limits.
Software & Data Management
The HL-3A operates as a standalone instrument with local digital control; no proprietary software or driver installation is required. The controller features non-volatile memory to retain last-used speed settings after power cycling. For integration into automated platforms, the unit provides TTL-compatible analog input (0–5 V or 0–10 V) and output signals for external speed modulation and status feedback (e.g., run/stop, direction, fault). Optional RS-485 interface modules (sold separately) enable Modbus RTU communication with PLCs, SCADA systems, or LIMS, supporting audit-trail-capable operation in regulated environments when combined with external data-logging infrastructure.
Applications
- Environmental monitoring: Continuous sampling of wastewater, groundwater, or air scrubber effluents into analyzers (e.g., IC, ICP-OES).
- Pharmaceutical R&D: Precise buffer delivery during column chromatography method development or dissolution testing.
- Academic teaching labs: Demonstrating fluid dynamics, flow calibration principles, and peristaltic pump mechanics in chemical engineering or biomedical courses.
- Hospital laboratories: Reagent dispensing in automated immunoassay platforms or dialysis simulation setups.
- Biotechnology: Feeding nutrient media in small-scale bioreactors or perfusion-based cell expansion systems.
FAQ
What tubing sizes are compatible with the HL-3A pump head?
Standard configurations support tubing inner diameters from 1.6 mm to 6.4 mm; optimal performance is achieved with 3.2 mm or 4.8 mm ID silicone tubing for the full 60–12,000 mL/h range.
Does the HL-3A support reversible flow direction?
No—the HL-3A is configured for unidirectional flow only. Reverse operation requires mechanical reorientation of the tubing path or use of an external valve manifold.
Can the HL-3A be used in sterile or cleanroom environments?
Yes—provided appropriate autoclavable or gamma-sterilizable tubing is installed and the pump head surface is cleaned using IPA or approved disinfectants per facility SOPs.
Is flow calibration included with the device?
Factory calibration is performed at three points (low/mid/high speed); users should conduct periodic volumetric verification using gravimetric or timed-collection methods per ISO 8655-4 guidelines.
What is the expected service life of the pump tubing under continuous operation?
With standard silicone tubing operating at ≤100 rpm and ambient temperature, typical service life ranges from 100–300 hours depending on fluid chemistry, pressure load, and tubing wall thickness.
