Overview
The LeadFluid BT600S Intelligent Speed-Controlled Peristaltic Pump is an industrial-grade laboratory peristaltic pump engineered for high-precision fluid handling in demanding analytical, bioprocessing, and quality control environments. Based on the principle of peristalsis—where rollers compress a flexible tubing to generate unidirectional flow—the BT600S eliminates fluid contact with mechanical components, ensuring contamination-free transfer of sensitive reagents, cell cultures, buffers, and aggressive solvents. Its closed-loop step motor drive system delivers exceptional speed stability and repeatability across its full operational range (0.1–600 rpm), enabling accurate volumetric delivery from microliter-scale dispensing to high-throughput media circulation. Designed for integration into automated workflows, the BT600S supports both standalone operation via its front-panel interface and seamless coordination with PLCs, SCADA systems, or LIMS through standardized industrial protocols.
Key Features
- High-resolution LCD display with switchable English/Chinese UI and intuitive parameter navigation
- Industrial membrane keypad with tactile feedback and extended service life under frequent use
- LF-EasyChange pump head architecture—compatible with multiple high-torque, multi-channel pump heads (e.g., YZ15, DT10, WG60) for flexible flow path configuration
- Precise speed control with resolution of 0.1 rpm (≤100 rpm) and 1 rpm (>100 rpm); speed accuracy maintained at < ±0.2% across load variations
- Programmable operation modes: time-controlled run/stop, intermittent cycling, volume-based dispensing (via time–speed correlation), and reverse-pulse backflow compensation to prevent post-shutdown drip
- Comprehensive safety and usability functions: key lockout, soft deceleration ramp, real-time status memory, and audible/visual alarm indicators
- Robust enclosure fabricated from AISI 304 stainless steel—resistant to common organic solvents, acids, and alkalis; surface finish optimized for wipe-down decontamination
- Dual-layer internal isolation design with conformal-coated PCBs, enhanced EMI shielding, and wide-input voltage tolerance (AC 100–240 V, 50/60 Hz)
Sample Compatibility & Compliance
The BT600S is compatible with a broad spectrum of elastomeric tubing materials—including silicone, Viton®, Tygon®, and Pharmapure®—enabling safe handling of aqueous, viscous, particulate-laden, and mildly corrosive fluids. Its tubing-centric fluid path meets USP Class VI and FDA-compliant material requirements when paired with certified tubing. The pump’s electrical architecture conforms to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards. While not certified as medical device hardware, it supports GLP/GMP-aligned workflows through audit-ready features including external signal logging, non-volatile parameter storage, and deterministic response timing—all critical for method validation under ISO/IEC 17025 or ASTM D3418 frameworks.
Software & Data Management
The BT600S integrates natively with LeadFluid’s LF-LCD-OS firmware, supporting local configuration and real-time monitoring without host dependency. Optional Bluetooth-enabled LeadFluid Mobile App extends remote supervision capabilities: users can initiate/terminate runs, adjust speed in real time, define timed sequences, and receive push notifications for pump tube replacement or fault conditions (e.g., motor stall, communication timeout). For industrial automation, the RS485 port implements Modbus RTU protocol (function codes 03h/06h/10h), allowing bidirectional register access to all operational parameters—including current speed, direction, elapsed runtime, and error flags. Analog and digital I/O ports support hardwired integration with level sensors, flow meters, or emergency stop circuits while maintaining galvanic isolation per IEC 60950-1.
Applications
- Automated liquid handling in HPLC mobile phase delivery, dialysis buffer exchange, and fermentation feed control
- Calibration and verification of flow meters and mass spectrometer sample introduction systems
- Continuous dosing in environmental water quality monitoring stations and wastewater treatment pilot lines
- Cell culture media perfusion in bioreactors and organ-on-chip platforms requiring pulseless, shear-sensitive flow
- Pharmaceutical QC labs performing dissolution testing, titration reagent delivery, and extractive sample preparation
- Academic research in microfluidics, electrochemistry, and synthetic biology where precise, low-shear fluid metering is essential
FAQ
What tubing sizes are supported by the BT600S?
The pump accommodates tubing inner diameters from 0.1 mm to 6.4 mm, depending on the installed pump head model (e.g., YZ15 supports 0.5–4.8 mm; DT10 supports 0.8–6.4 mm). Tubing selection must consider pressure rating, chemical compatibility, and required flow rate.
Can the BT600S be integrated into a PLC-controlled manufacturing line?
Yes—via RS485 Modbus RTU or opto-isolated digital/analog I/O, the pump accepts start/stop, direction, and speed commands from programmable logic controllers and returns operational status signals compliant with industrial control architectures.
Is firmware upgrade supported in-field?
Firmware updates are performed via USB-to-RS232 adapter using LeadFluid’s official PC utility software; version history and release notes are published on the manufacturer’s technical documentation portal.
Does the pump meet electromagnetic compatibility requirements for laboratory use?
It complies with CISPR 11 Group 1, Class B emission limits and IEC 61326-1 immunity specifications for professional laboratory equipment, ensuring stable operation near sensitive instrumentation such as NMR spectrometers or electron microscopes.
What maintenance intervals are recommended for long-term reliability?
Pump tube replacement frequency depends on operating speed, pressure load, and tubing material—typically every 100–500 hours under continuous use. Motor and gear assembly require no scheduled lubrication; periodic visual inspection of tubing compression alignment and housing seals is advised per ISO 5840-3 maintenance guidelines.
