LeadFluid BT101L Flow-Mode Intelligent Peristaltic Pump

Overview

The LeadFluid BT101L Flow-Mode Intelligent Peristaltic Pump is an engineered solution for precise, repeatable, and programmable fluid handling in analytical laboratories, bioprocessing workflows, and automated chemical dosing systems. Based on the positive displacement principle of peristaltic pumping—where rollers compress flexible tubing to generate unidirectional flow—the BT101L delivers contamination-free transfer without valve or seal contact with the fluid path. Its core architecture integrates high-resolution motor control, real-time flow monitoring, and embedded intelligence to support both manual operation and integration into larger process control environments. Designed for compliance-critical applications, the pump operates within defined environmental tolerances (0–40 °C, <80% RH) and meets IP31 mechanical protection requirements for laboratory-grade durability. The dual-layer isolated electronics board, coated with industry-standard conformal coating, ensures stable performance under variable line voltage conditions (AC 100–240 V, 50/60 Hz) and mitigates electromagnetic interference in multi-instrument lab settings.

Key Features

• True-color TFT-LCD touchscreen interface with tactile keypad backup for intuitive local operation
• Proprietary LF-Touch-OS firmware: a dedicated peristaltic pump operating system supporting flow calibration, dose memory, direction reversal, full-speed override, and state retention across power cycles
• High-precision speed control: 0.1 rpm resolution with < ±0.2% speed accuracy, enabling reproducible volumetric delivery across the full 0.00011–750 mL/min range
• Integrated flow quantification: real-time flow rate display, cumulative volume tracking, and user-accessible flow calibration using standardized syringe or gravimetric methods
• “Precision Dispensing” mode: motor-step-based volume delivery—superior to time-based dispensing due to direct correlation between step count and displaced volume, minimizing timing drift and tubing elasticity effects
• Active thermal management: intelligent fan control maintains acoustic output ≤45 dB(A), reducing ambient noise in shared lab spaces
• Industrial-grade connectivity: opto-isolated digital I/O (5 V / 12 V standard), analog speed modulation (0–5 V standard), and RS485 serial interface compliant with Modbus RTU protocol for PLC, SCADA, or LIMS integration
• Modular pump head compatibility: supports interchangeable pump heads (e.g., YZ15, YZ25, DG series) to adapt flow capacity, pressure rating, and tubing size (ID 0.5–6.4 mm) to application-specific requirements

Sample Compatibility & Compliance

The BT101L is chemically agnostic—fluid compatibility depends solely on tubing material selection (e.g., silicone, Viton®, Tygon®, PharMed® BPT), enabling safe handling of aqueous buffers, organic solvents, acids, bases, and shear-sensitive biologics. Its tube-only wetted path eliminates cross-contamination risk and simplifies cleaning validation. While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its audit-ready features—including non-volatile parameter storage, timestamped operation logs (when paired with external logging), and deterministic control logic—support alignment with GLP and GMP documentation practices. The pump’s Modbus interface facilitates traceable command execution in regulated environments where electronic records must be attributable, legible, and retained.

Software & Data Management

LF-Touch-OS provides embedded configuration and operational logging without requiring external software. All user-modifiable parameters—including target speed, dispensing volume, ramp profiles, and calibration coefficients—are stored in non-volatile memory. When connected via RS485, the pump accepts Modbus function codes (03h, 06h, 10h) for remote read/write access to registers containing real-time status (running/stopped, direction, current speed), accumulated volume, and error flags. Third-party software (e.g., LabVIEW, Python with pymodbus, MATLAB) can poll these registers at configurable intervals for data synchronization with ELN or MES platforms. No proprietary drivers are required; standard Modbus RTU over RS485 suffices.

Applications

• Automated reagent dispensing in clinical analyzers and ELISA workstations
• Continuous feed control in small-scale bioreactors and perfusion culture systems
• Calibration standard delivery in HPLC and IC autosamplers
• Controlled eluent flow in column chromatography and affinity purification setups
• Environmental water sampling—low-flow, pulseless delivery for turbidity-sensitive measurements
• Microfluidic device priming and reagent loading in academic and pharmaceutical R&D labs
• Integration into OEM instrumentation requiring silent, low-maintenance, and programmable fluid actuation

FAQ

Does the BT101L support closed-loop flow feedback?
No—it operates as an open-loop volumetric device calibrated against tubing geometry and motor step count. For true closed-loop flow control, integrate with an external flow sensor (e.g., Coriolis or ultrasonic) and use the analog input for speed modulation.
Can the pump be used with corrosive fluids such as concentrated HCl or NaOH?
Yes—provided compatible tubing (e.g., Viton® for acids, EPDM for alkalis) is selected and regularly inspected for swelling or degradation. Tubing life must be validated per application.
Is firmware upgradable in the field?
Yes—firmware updates are delivered via USB flash drive using the built-in DFU (Device Firmware Upgrade) mode accessible through the service menu.
What is the maximum backpressure the BT101L can sustain?
Maximum sustainable backpressure depends on tubing ID, wall thickness, and pump head type. With standard silicone tubing (ID 3.2 mm) and YZ15-13 pump head, typical limit is ~1.5 bar at 150 rpm. Refer to LeadFluid’s tubing performance charts for quantitative data.
Does the pump meet electromagnetic compatibility (EMC) standards for CE marking?
The BT101L complies with EN 61326-1:2013 (Laboratory Equipment EMC) and EN 61000-6-3:2011 (Emission Standard), verified during factory testing. Full CE documentation is available upon request.
