Overview
The LeadFluid BT600L Intelligent Flow-Mode Peristaltic Pump is engineered for high-precision fluid handling in analytical laboratories, bioprocessing workflows, and automated synthesis systems. Based on the positive displacement principle of peristaltic pumping—where rollers compress a flexible tubing segment to displace fluid—the BT600L delivers contamination-free, pulse-minimized flow without valve wear or seal degradation. Its core design prioritizes metrological integrity: microstepping motor control ensures stable speed regulation across the full 0.1–600 rpm range, enabling reproducible volumetric delivery from microliter-scale reagent dosing to high-throughput media transfer at up to 3000 mL/min. Unlike pressure-driven pumps, the BT600L maintains consistent flow regardless of backpressure fluctuations (within tubing burst limits), making it suitable for inline filtration, column loading, and closed-loop perfusion applications where fluid sterility and tubing compatibility are critical.
Key Features
- 4.3-inch color TFT-LCD touchscreen with tactile keypad support, running the proprietary LF-Touch-OS firmware for deterministic response and long-term stability.
- Dual-mode operation: direct flow rate (mL/min) or rotational speed (rpm) entry, with real-time conversion and display using calibrated tubing profiles.
- Advanced dispensing logic: five pre-stored volume/time programs, programmable delay start and timed stop (up to 999 hours), and automatic suction-back to eliminate drip after termination.
- Adaptive thermal management system adjusts fan speed based on ambient temperature and motor load, maintaining optimal operating temperature without manual intervention.
- Industrial-grade isolation: optically isolated digital I/O and galvanically isolated analog interfaces (0–5 V, 0–10 V, 4–20 mA) ensure noise immunity in electromagnetically complex environments (e.g., near centrifuges or RF equipment).
- Robust mechanical construction: brushed stainless-steel (AISI 304) chassis resists corrosion from common organic solvents (e.g., ethanol, acetone, IPA) and supports wipe-down decontamination protocols.
- Conformal-coated PCBs meet IPC-CC-830B Class 3 standards for humidity, dust, and condensation resistance—validated under sustained 80% RH conditions.
Sample Compatibility & Compliance
The BT600L is compatible with standard peristaltic pump tubing materials including PharmPure® silicone, Tygon® LFL, Norprene®, and Viton®—all certified for USP Class VI and FDA 21 CFR 177.2600 compliance. Tubing selection directly governs maximum pressure rating, chemical resistance, and particulate generation; users must validate tubing against their specific fluid matrix and flow profile per ISO 8536-4 (infusion equipment) and ASTM D2240 (durometer). The pump’s open architecture supports third-party tubing calibration files, enabling traceable flow verification per ISO/IEC 17025 requirements when used in GLP-regulated environments. While the device itself carries CE marking (EMC Directive 2014/30/EU, LVD Directive 2014/35/EU), end-user responsibility includes verifying full system compliance—including tubing, fittings, and downstream components—under applicable regional regulations (e.g., EU MDR, FDA QSR).
Software & Data Management
Local operation is fully managed via LF-Touch-OS, supporting audit-trail-capable parameter logging (timestamped speed, flow, duration, cycle count) stored internally for ≥10,000 events. For networked integration, the built-in Wi-Fi module enables secure TLS 1.2–encrypted communication with the official LeadFluid LabControl mobile application (iOS/Android), providing remote monitoring, alarm notification (e.g., pump tube replacement due date, overtemperature warning), and firmware OTA updates. RS485 Modbus RTU implementation (slave ID configurable, baud rates 9600–115200) permits seamless integration into SCADA, PLC, or LIMS platforms. All Modbus registers—including real-time status flags, setpoint values, and error codes—are documented in the publicly available protocol manual (v3.2), facilitating custom driver development. No cloud storage is enabled by default; data residency remains on-device unless explicitly configured via authenticated API endpoints.
Applications
- Automated sample preparation for HPLC, IC, and ICP-MS—precise metering of diluents, standards, and internal controls.
- In-line continuous bioreactor feed and harvest, compliant with single-use fluid path requirements.
- Pharmaceutical QC labs performing USP <724> dissolution testing with programmable pulsation-free flow.
- Environmental water analysis: low-flow sampling from wells or streams with integrated timer-based duty cycling.
- Academic research in microfluidics and organ-on-chip systems requiring sub-mL/min precision and bidirectional flow reversal.
- Chemical synthesis reactors where solvent addition must be decoupled from pressure transients in sealed vessels.
FAQ
What tubing sizes are supported by the BT600L?
The pump head accommodates tubing inner diameters from 0.1 mm to 4.8 mm (e.g., Masterflex L/S 13–24, PharMed BPT 0.5–3.2 mm), with flow calibration required per size and material.
Does the BT600L support FDA 21 CFR Part 11 compliance?
While the device provides electronic records and audit trails, full Part 11 compliance requires validation of the entire workflow—including user access controls, electronic signatures, and data integrity policies—per your organization’s SOPs.
Can the pump operate continuously for extended periods?
Yes; thermal management and conformal-coated electronics enable unattended 24/7 operation within specified ambient conditions (0–40 °C, <80% RH).
Is external analog control compatible with 0–10 V and 4–20 mA signals?
Yes—input signal type is software-configurable via Modbus register or local UI; output feedback is fixed at 0–5 V proportional to actual speed.
How is flow accuracy validated?
Using the guided flow calibration wizard, users perform gravimetric measurement at three points across the flow range (low/mid/high), generating a correction curve applied in real time during operation.
