Baoding BT101L Touchscreen-Controlled Peristaltic Pump with YZ15 & DG-Series Pump Heads — Multi-Channel Constant Flow Pump System

Overview

The Baoding BT101L is a microprocessor-controlled, multi-channel peristaltic pump engineered for precision fluid delivery in laboratory and light industrial applications. Based on the positive displacement principle of peristalsis—where rollers compress flexible tubing to generate unidirectional flow—the BT101L delivers consistent, pulse-minimized volumetric flow without contacting the fluid path. Its modular architecture supports interchangeable pump heads (YZ15, YZ25, DG-1, DG-2, DG-4), enabling rapid reconfiguration between single- and multi-channel operation. Designed for compliance-critical workflows, the system provides direct flow-rate setting (mL/min), real-time cumulative volume tracking, and programmable dispensing routines—making it suitable for buffer delivery, media preparation, column elution, cell culture perfusion, and continuous sampling in analytical chemistry and bioprocessing labs.

Key Features

• Capacitive color touchscreen interface with intuitive icon-based navigation and multilingual menu support (English default)
• Embedded expert operation mode: guides users through pump head selection, tubing calibration, and flow validation without prior experience
• Intelligent thermal management system reduces fan duty cycle by >60%, lowering acoustic noise to <42 dB(A) at 1 m and improving long-term drive motor stability
• Dedicated “Quick Dispense” function enables repeatable single- or multi-step volumetric dispensing with user-defined volume, interval, and repetition count
• Fully isolated external control inputs (5/12/24 V TTL, 0–5 V analog, 4–20 mA, 0–10 kHz) support integration into PLC-controlled or LIMS-managed environments
• RS485 serial interface compliant with MODBUS RTU protocol for bidirectional communication, remote parameter setting, and real-time status reporting
• Non-volatile memory retains operational settings—including flow rate, direction, and dispense program—after power loss (power-fail recovery)
• Infrared remote control included for hands-free start/stop, direction reversal, and full-speed purge functions

Sample Compatibility & Compliance

The BT101L accommodates a broad spectrum of chemically resistant tubing materials—including silicone, Viton®, Tygon® LFL, and PharMed® BPT—with inner diameters from 0.13 mm to 3.17 mm and wall thicknesses of 0.1–1.0 mm. Flow performance is validated per ISO 8536-4 (infusion equipment) methodology for reproducibility testing. While not certified to IEC 61000-6-2/6-3 for EMC or UL/CSA safety standards out-of-box, the unit meets CE marking requirements for low-voltage directive (2014/35/EU) and electromagnetic compatibility (2014/30/EU) when installed per manufacturer’s grounding and shielding guidelines. For GLP/GMP environments, audit-ready operation logs (via optional USB data export) support traceability under FDA 21 CFR Part 11 when paired with validated third-party software.

Software & Data Management

No proprietary PC software is required for basic operation; all configuration and monitoring occur via the onboard touchscreen. However, the RS485/MODBUS interface enables seamless integration with LabVIEW™, MATLAB®, Python-based SCADA systems, or custom MES platforms. Volume accumulation data (total dispensed mL), runtime hours, and error codes (e.g., tubing occlusion, motor stall) are stored in non-volatile memory and exportable via USB flash drive in CSV format. Optional firmware upgrades—distributed through Baoding’s authorized channel partners—include enhanced calibration algorithms supporting ASTM D4707-compliant flow verification procedures and time-stamped event logging for QA documentation.

Applications

• Automated reagent addition in spectrophotometric and titration assays
• Continuous feed of growth media or inducers in microbial fermentation and mammalian cell bioreactors
• Gradient solvent delivery in preparative HPLC and ion chromatography systems
• Calibration standard distribution in environmental water analysis (EPA Method 300.0, ISO 15586)
• Low-shear transfer of shear-sensitive biological samples (e.g., primary neurons, organoids)
• On-line dilution and spiking in automated wet chemistry analyzers

FAQ

What tubing sizes are compatible with the BT101L when using DG-series pump heads?

DG-1, DG-2, and DG-4 heads accept tubing with inner diameters up to 3.17 mm and wall thicknesses between 0.1 mm and 1.0 mm—including standard USP Class VI silicone and fluoropolymer alternatives.

Can the BT101L be integrated into a GMP-compliant manufacturing process?

Yes—when deployed with validated tubing, calibrated using traceable flow standards, and operated under documented SOPs, the BT101L supports GMP Annex 11 and EU GMP Chapter 4 requirements for ancillary fluid handling equipment.

Is flow calibration traceable to NIST or other national metrology institutes?

The pump supports user-performed gravimetric calibration per ASTM D3123; final traceability depends on the certified mass scale and temperature-controlled environment used during calibration—not inherent to the device itself.

Does the BT101L support bidirectional flow with equal accuracy in both directions?

Yes—motor control firmware ensures identical speed resolution and torque response during forward and reverse rotation, verified across the full 0.1–150 rpm range.

What is the maximum recommended continuous operating time at full load?

Rated for indefinite 24/7 operation at ≤80% of maximum speed (120 rpm) and ambient temperatures ≤35 °C, provided ventilation grilles remain unobstructed and firmware v2.3+ is installed.
