Overview
The HL-6D is a single-channel, microprocessor-controlled peristaltic pump engineered for high-volume fluid transfer in laboratory, pilot-scale, and light industrial applications. It operates on the principle of positive displacement via roller compression of flexible tubing—eliminating fluid contact with internal pump components and ensuring contamination-free operation. Designed for reproducible volumetric delivery under variable back pressure conditions, the HL-6D delivers stable flow across its full range (2–150 L/h) without recalibration, making it suitable for continuous perfusion, media feeding, buffer exchange, and automated filling protocols. Its robust aluminum alloy chassis and thermally stable motor housing support extended duty cycles in ambient environments (10–40 °C), while the sealed control electronics meet IP20 ingress protection standards for typical lab bench use.
Key Features
- Wide adjustable flow range: 2,000–150,000 mL/h, achieved through precise digital speed control (RPM-based tuning) with resolution down to 1 rpm
- Integrated digital display showing real-time rotational speed (rpm), elapsed time, and remaining timer duration
- Three operational modes: Continuous Run, Time-Controlled Delivery (programmable start/stop), and Volume-Based Dispensing (Fill Mode) with automatic shut-off upon target volume achievement
- Non-volatile memory retains last-used parameters—including speed, timer settings, and mode selection—after power cycling
- High-torque stepper motor coupled with precision-machined roller assembly ensures consistent occlusion and minimal pulsation (<±3% peak-to-peak variation at mid-range flow)
- Front-panel membrane keypad with tactile feedback and LED status indicators for intuitive operation without software dependency
- Standard 1/4″–3/8″ tubing compatibility (e.g., PharMed BPT, Norprene, Viton); tube life optimized via adjustable roller pressure calibration
Sample Compatibility & Compliance
The HL-6D handles aqueous solutions, organic solvents (with compatible tubing), cell culture media, buffers, acids/bases (pH 1–14, dependent on tubing chem-resistance), and particulate-laden suspensions up to 100 µm particle size. It complies with IEC 61000-6-3 (EMC Emission Standards) and IEC 61000-6-2 (Immunity). While not certified for hazardous area use (ATEX/IECEx), it is suitable for general-purpose Class 1, Division 2 environments when paired with appropriate tubing and enclosure. The pump architecture supports GLP-aligned workflows: all timed operations generate traceable timestamps; parameter changes are non-volatile and auditable via manual log entry. It meets mechanical safety requirements per ISO 13857 and electrical safety per IEC 61010-1 for Laboratory Equipment.
Software & Data Management
The HL-6D operates as a standalone instrument with no mandatory PC interface; however, optional RS-485 serial communication (Modbus RTU protocol) enables integration into SCADA or LIMS platforms for remote command execution (start/stop/pause), real-time speed polling, and event logging. No proprietary drivers or cloud services are required. All timing and dispensing events are locally timestamped with second-level precision. For regulated environments, users may implement external audit trails via connected data loggers compliant with FDA 21 CFR Part 11 requirements—though the pump itself does not include electronic signature or user-role management features. Firmware updates (if released) are performed via USB-to-serial adapter using vendor-provided configuration utility.
Applications
- Continuous bioreactor feed and harvest in upstream processing (USP)
- Automated column packing and eluent delivery in preparative chromatography systems
- High-flow dialysis and tangential flow filtration (TFF) recirculation loops
- Calibration standard delivery in water quality testing labs (e.g., EPA Method 300.0)
- Controlled reagent addition in environmental simulation chambers and corrosion test rigs
- Volume-accurate filling of reaction vessels, carboys, or intermediate bulk containers (IBCs) in R&D scale-up
- Media perfusion in 3D tissue culture bioreactors requiring stable shear profiles
FAQ
What tubing sizes are recommended for optimal performance at maximum flow rate?
For 150 L/h operation, use 3/8″ (9.5 mm) ID silicone or PharMed BPT tubing with wall thickness ≥1.6 mm; minimum bend radius must exceed 50 mm to prevent premature fatigue.
Does the HL-6D support analog input for external flow rate modulation?
No—speed is controlled exclusively via front-panel interface or Modbus RTU commands; 0–10 V or 4–20 mA analog inputs are not supported.
Can the timer be used simultaneously with volume dispensing mode?
Yes—the Fill Mode incorporates dual termination logic: it stops either upon reaching the programmed volume or exceeding the preset timer limit, whichever occurs first.
Is the pump rated for sterile applications?
The pump head and housing are cleanable with 70% ethanol or 0.5% sodium hypochlorite; however, it lacks ISO 14644-1 Class 5 certification and is not supplied with pre-sterilized tubing assemblies.
What maintenance intervals are recommended for long-term reliability?
Inspect tubing for cracking or flattening every 200 hours of operation; replace rollers and bearings every 10,000 hours or per manufacturer’s service bulletin—no scheduled lubrication is required.
