Overview
The LeadFluid BT100S Variable-Speed Peristaltic Pump is an industrial-grade laboratory peristaltic pump engineered for precision fluid handling in demanding analytical, bioprocessing, and quality control environments. Based on the principle of positive displacement via roller compression of flexible tubing—commonly referred to as peristalsis—the BT100S delivers highly reproducible, pulse-free flow without introducing contamination or shear stress to sensitive fluids such as cell suspensions, enzymes, reagents, or sterile media. Its closed-fluid-path design eliminates contact between the pump mechanism and the transported liquid, making it ideal for applications requiring strict cross-contamination control, aseptic transfer, or compatibility with aggressive solvents. Designed for integration into automated workflows, the BT100S supports both standalone operation and seamless coordination with PLCs, SCADA systems, and custom lab automation platforms through standardized communication protocols.
Key Features
- High-torque stepper motor drive ensures stable rotation across the full speed range (0.1–150 rpm), enabling precise volumetric delivery from nanoliter-scale dosing to high-throughput transfer (up to 750 mL/min).
- LF-LCD-OS firmware with backlit dot-matrix LCD display offers intuitive parameter configuration and real-time status feedback; bilingual interface (English/Chinese) simplifies operation in multinational labs.
- LF-EasyChange modular pump head architecture accommodates multiple high-performance pump heads (e.g., YZ15, DT10, or customized variants), supporting diverse tubing inner diameters (ID: 0.1–6.4 mm) and flow profiles.
- Programmable timing functions include run duration, pause interval, and cycle count (1–999 or infinite), facilitating repeatable liquid dispensing, timed sampling, and multi-step assay protocols.
- Engineered anti-drip functionality includes programmable deceleration ramping and reverse suction (backflow compensation), minimizing post-stop droplet formation—a critical requirement for gravimetric accuracy and reagent conservation.
- Robust mechanical construction features a 304 stainless steel enclosure resistant to organic solvents and routine disinfectants; dual-layer internal isolation enhances protection against dust, moisture, and chemical vapor ingress (IP31 rated).
- Wide-input power supply (AC 100–240 V, 50/60 Hz) and opto-isolated I/O ensure reliable performance under variable electrical conditions common in shared lab infrastructure or mobile deployment scenarios.
Sample Compatibility & Compliance
The BT100S is compatible with a broad spectrum of chemically resistant tubing materials—including silicone, Viton®, Tygon®, and Pharmapure®—enabling safe handling of aqueous buffers, acids, bases, alcohols, and hydrocarbon-based solvents. Its non-metallic fluid path (tubing only) avoids catalytic degradation or leaching, preserving sample integrity in pharmaceutical QC, environmental analysis, and academic research. While not certified as GMP-compliant out-of-the-box, the pump’s traceable operation (via external logging), deterministic timing, and configurable audit-ready parameters align with GLP documentation requirements. Optional remote monitoring via LeadFluid Mobile App supports basic event logging (e.g., pump stop alerts, tubing replacement reminders), facilitating adherence to internal SOPs. RS485 Modbus RTU support enables integration into FDA 21 CFR Part 11–compliant systems when paired with validated host software and electronic signature controls.
Software & Data Management
The embedded LF-LCD-OS firmware provides local control with persistent memory for all user-defined settings—including speed, timing sequences, and direction preferences—ensuring consistent startup behavior after power cycling. For centralized management, the optional LeadFluid Mobile App (iOS/Android) extends functionality via Bluetooth or Wi-Fi, allowing remote start/stop, real-time speed adjustment, and scheduled task execution. All app-initiated commands are timestamped and logged locally on the device. The RS485 interface supports bidirectional Modbus RTU communication (DB15 connector), permitting read/write access to operational registers—including current speed, elapsed runtime, direction status, and fault flags—for integration with LabVIEW, Python-based control scripts, or MES platforms. Analog input options (0–5 V / 0–10 V / 4–20 mA) allow analog setpoint control in process-critical applications where external sensors regulate flow demand dynamically.
Applications
- Automated liquid handling in HPLC and IC sample introduction systems, where low-pulse flow minimizes baseline noise and column overpressure.
- Cell culture media perfusion and feeding in bioreactors and microfluidic organ-on-chip platforms requiring gentle, non-shearing transport.
- Calibration and validation of flow meters and mass spectrometry sample introduction lines using gravimetric or timed-volume verification.
- Reagent dispensing in ELISA, PCR setup, and clinical chemistry analyzers—particularly where tube-based reagent storage reduces carryover risk.
- Environmental water testing workflows involving sequential filtration, preservation agent addition, and aliquoting into analytical vials.
- In-line pH or conductivity probe calibration loops, where controlled, bubble-free delivery ensures sensor response fidelity.
FAQ
What tubing sizes are supported by the BT100S?
The pump is compatible with tubing IDs ranging from 0.1 mm to 6.4 mm, depending on the installed pump head model (e.g., YZ15 supports 0.5–4.8 mm ID; DT10 supports 0.1–2.4 mm ID). Tubing selection must consider chemical compatibility, pressure rating, and required flow rate.
Does the BT100S support analog speed control?
Yes—it accepts 0–5 V, 0–10 V, or 4–20 mA analog input signals for continuous speed modulation, with user-selectable scaling via the front panel or RS485 command set.
Can the pump be integrated into a PLC-controlled system?
Yes—opto-isolated digital I/O and RS485 Modbus RTU enable direct connection to industrial PLCs. Predefined Modbus register maps are provided in the technical manual for seamless mapping of start/stop, direction, speed, and status signals.
Is the stainless steel housing resistant to common lab solvents?
The 304 stainless steel enclosure resists corrosion from ethanol, isopropanol, acetone, dilute acids/bases, and standard cleaning agents. Prolonged exposure to chlorinated solvents or strong oxidizers is not recommended.
What safety certifications does the BT100S hold?
The device complies with IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and meets EMC standards per IEC 61326-1. CE marking is applied for the EU market; UL/cUL listing is available upon request for North American deployments.
