LeadFluid BT300S Variable-Speed Peristaltic Pump

Overview

The LeadFluid BT300S Variable-Speed Peristaltic Pump is an industrial-grade, microprocessor-controlled fluid transfer system engineered for precision, repeatability, and long-term reliability in laboratory, pilot-scale, and light industrial applications. Utilizing the fundamental principle of peristalsis—where rollers compress a flexible tubing segment against a curved housing to generate positive displacement—the BT300S delivers pulse-free, contamination-free flow without exposing fluids to mechanical seals or valves. Its high-torque stepper motor drive ensures stable rotational dynamics across the full speed range (0.1–350 rpm), enabling accurate volumetric delivery from microliter-per-minute dosing to bulk transfer at up to 1750 mL/min. Designed for integration into automated workflows, the pump supports both standalone operation via its front-panel interface and seamless coordination with PLCs, SCADA systems, or custom control platforms through standardized communication protocols.

Key Features

• High-resolution LCD display with switchable English/Chinese UI and intuitive parameter navigation
• Industrial membrane keypad with tactile feedback and extended mechanical lifecycle
• LF-EasyChange pump head architecture—compatible with multiple high-performance pump heads (e.g., YZ15, YZ25, DG series) for adaptable flow and pressure capability
• Programmable operational modes: continuous run, timed dispensing, interval cycling (1–999 cycles; 0 = infinite), and multi-step sequences
• Advanced fluid handling safeguards: programmable ramp-down deceleration, post-stop suction reversal to prevent drip, and key lock function to avoid unintended parameter changes
• Robust enclosure fabricated from electropolished AISI 304 stainless steel—resistant to organic solvents, acids, and alkalis; surface-smooth design facilitates cleaning and meets hygienic lab standards
• Dual-layer internal isolation: separated power and signal circuitry with conformal coating and enhanced EMI shielding for stable operation in electrically noisy environments
• Wide-input universal power supply (AC 100–240 V, 50/60 Hz) with active power factor correction and thermal protection

Sample Compatibility & Compliance

The BT300S is chemically inert with respect to the pumped medium—fluid contact is limited exclusively to the tubing material (e.g., silicone, Viton®, Pharmed® BPT, Tygon®). Users select tubing based on chemical compatibility, pressure rating, and regulatory requirements (e.g., USP Class VI, FDA 21 CFR 177.2600, ISO 10993). While the pump itself does not require fluid certification, its construction and electrical design comply with CE directives under EN 61010-1 (safety for laboratory equipment) and EN 61326-1 (EMC for measurement and control devices). The IP31 rating indicates protection against vertically falling droplets and solid objects >2.5 mm—suitable for controlled indoor laboratory environments. For GxP-regulated processes, optional audit-trail-capable software (via LF-LCD-OS or third-party SCADA integration) supports ALCOA+ data integrity principles when paired with appropriate validation documentation.

Software & Data Management

The embedded LF-LCD-OS firmware provides real-time monitoring of speed, elapsed time, cycle count, and system status. Via RS485 Modbus RTU (DB15 connector), the pump integrates into distributed control architectures for centralized command, telemetry, and event logging. Optional LeadFluid mobile application enables remote start/stop, speed adjustment, schedule programming, and alert notifications—including pump tube replacement reminders and fault-triggered alarms. Analog and digital I/O support allows hardware-level synchronization with external sensors (e.g., level switches, flow meters) or actuators (e.g., solenoid valves, peristaltic pump arrays). All external control signals feature opto-isolation to eliminate ground-loop interference. When connected to compliant data acquisition systems, timestamped operational logs can be archived for traceability in GLP, GMP, or ISO/IEC 17025 workflows.

Applications

• Automated reagent dispensing in analytical chemistry and clinical diagnostics
• Continuous feed in bioreactor nutrient/perfusion systems
• Calibration and verification of flow meters and liquid handling instruments
• Chromatography mobile phase delivery (low-pressure HPLC, FPLC, SEC)
• Environmental sampling—sequential water extraction, leachate collection, and inline filtration
• Pharmaceutical formulation R&D: excipient blending, granulation fluid addition, and dissolution testing
• Food & beverage quality control: viscosity-adjusted product transfer, flavor dosing, and fill-volume verification

FAQ

What tubing sizes are supported by the BT300S?
The pump accommodates standard peristaltic tubing with inner diameters ranging from 0.1 mm to 6.4 mm, depending on the installed pump head (e.g., YZ15 for ID ≤ 3.2 mm; DG series for higher pressure and larger ID).
Can the BT300S operate continuously for extended periods?
Yes—the motor and thermal management system are rated for indefinite duty cycle under ambient conditions ≤40°C and relative humidity <80%. Continuous operation is validated per IEC 60068-2 environmental stress testing.
Is Modbus RTU configuration required for basic operation?
No—RS485 communication is optional. All core functions (speed, direction, timing, memory recall) are fully accessible via the front panel without external connectivity.
Does the pump meet electromagnetic compatibility requirements for use in regulated labs?
Yes—it conforms to EN 61326-1 Class A emission limits and immunity thresholds for industrial environments, and has been independently tested for radiated/conducted emissions, ESD, and surge immunity.
How is calibration traceability maintained?
While the BT300S does not include built-in flow calibration, its speed accuracy (<±0.2%) is verified against NIST-traceable tachometric references during factory testing. End users may perform volumetric verification using certified graduated cylinders and stopwatch timing per ASTM D1193 or ISO 8504-2 methodologies.
