LeadFluid BT300L Intelligent Flow-Mode Peristaltic Pump

Overview

The LeadFluid BT300L Intelligent Flow-Mode Peristaltic Pump is an industrial-grade, microprocessor-controlled peristaltic pump engineered for precise, repeatable fluid handling in laboratory, bioprocessing, and analytical automation environments. Utilizing the fundamental principle of peristalsis—where rollers compress a flexible tubing segment to generate unidirectional flow—the BT300L delivers pulse-free, contamination-free transfer without valve or seal contact with the fluid path. Its design prioritizes metrological integrity: flow is derived from calibrated tubing geometry, rotational kinematics, and real-time speed feedback, enabling traceable volumetric delivery across a wide dynamic range (0.005–1750 mL/min). The pump integrates dual control paradigms—flow-rate mode (mL/min) and rotational speed mode (rpm)—with microstepping motor control ensuring high positional repeatability and minimized mechanical hysteresis. It is suitable for continuous infusion, timed dispensing, gradient generation, and closed-loop integration within GLP-compliant workflows.

Sample Compatibility & Compliance

The BT300L is compatible with standard peristaltic pump tubing materials including PharmPure® silicone, Tygon® LFL, C-Flex®, and Viton®—all certified to USP Class VI and FDA 21 CFR 177.2600 for liquid handling in pharmaceutical manufacturing. Its tubing compression geometry accommodates inner diameters from 0.1 mm to 6.4 mm, supporting applications ranging from nanoliter-scale reagent dosing to bulk media transfer. The device meets IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) for electromagnetic compatibility in shared lab infrastructure. While not intrinsically safe, its IP31 rating confirms protection against vertically falling drips and solid objects >2.5 mm—suitable for general-purpose benchtop use in ISO/IEC 17025-accredited testing laboratories. All firmware logs—including runtime, error events, and parameter changes—are timestamped and stored locally for audit trail generation per ALCOA+ principles.

Software & Data Management

The BT300L operates natively with LeadFluid’s cross-platform mobile application (iOS/Android), enabling remote configuration, real-time status monitoring, and event-triggered notifications (e.g., pump tube replacement alerts, overtemperature warnings, or communication timeouts). The app supports export of operational logs in CSV format for downstream analysis in Excel or statistical process control (SPC) software. For enterprise deployment, the RS485 interface enables integration into centralized asset management systems via Modbus TCP gateways. Firmware versions are digitally signed and validated during OTA updates to ensure integrity. Audit trails include user-initiated actions, parameter modifications, and system health diagnostics—fully compliant with FDA 21 CFR Part 11 requirements when deployed with appropriate access controls and electronic signature validation.

• Environmental water sampling systems with timed, depth-resolved collection protocols
• Integration into ISO 15197-compliant point-of-care diagnostic instrument platforms

FAQ

What tubing sizes are supported by the BT300L?
The pump head accepts tubing with inner diameters from 0.1 mm to 6.4 mm; recommended maximum wall thickness is 2.4 mm for optimal roller compression life and flow linearity.
Does the BT300L support flow calibration traceable to NIST standards?
Yes—users may perform gravimetric or volumetric calibration using certified reference standards; calibration coefficients are stored per tubing type and retained across power cycles.
Can the pump be integrated into a PLC-controlled production line?
Yes—via galvanically isolated digital I/O and RS485 Modbus RTU, supporting both discrete control and register-based parameter setting in accordance with IEC 61131-3 programming environments.
Is firmware update history logged and exportable?
Yes—each firmware version change is recorded with timestamp, user ID (if authenticated), and checksum verification status; logs are accessible via USB export or API call.
What safety certifications does the BT300L hold?
It complies with CE marking requirements (EMC Directive 2014/30/EU and LVD Directive 2014/35/EU), RoHS 2011/65/EU, and meets UL 61010-1 third-party test criteria for laboratory equipment safety.
