Chuding Tech BT100F / BT300F / BT600F Intelligent Dispensing Peristaltic Pump (Timer, Volumetric, and Replicate Dispensing Mode)

Overview

The Chuding Tech BT100F, BT300F, and BT600F series are intelligent dispensing peristaltic pumps engineered for high-precision fluid handling in laboratory, bioprocessing, and analytical applications. Based on the positive displacement principle of peristalsis—where rollers compress flexible tubing to generate unidirectional flow—these pumps deliver pulse-free, contamination-free, and shear-sensitive fluid transfer without valves or seals. Unlike conventional time-based dosing systems, the BT-series employs closed-loop motor angle control to eliminate acceleration/deceleration-induced volumetric drift, ensuring reproducible delivery across repeated cycles. The modular architecture supports interchangeable pump heads—including YZ15, YZ25, DG1, and DG2—enabling adaptation to diverse tubing geometries and flow requirements. Designed for integration into automated workflows, each model features native support for industrial communication protocols and real-time external modulation, making it suitable for GLP-compliant liquid handling, reagent dispensing in ELISA platforms, buffer exchange in chromatography systems, and continuous feeding in small-scale bioreactors.

Key Features

• 65,535-color high-resolution TFT touchscreen with intuitive graphical interface and multi-language support (English default)
• Embedded expert system that recommends optimal tubing material (e.g., Santoprene®, Viton®, silicone), inner diameter, wall thickness, and pump head type based on user-defined flow rate, total volume, and operating duration
• Three dispensing modes: timer-based (duration-controlled), volumetric (target-volume-driven), and replicate (repeat last dispensing sequence with one-touch recall)
• Cumulative volume tracking with non-volatile memory retention—even after power loss—to support audit-ready usage logs
• Intelligent thermal management with variable-speed fan control reduces acoustic noise to <45 dB(A) during extended operation
• Infrared remote control for hands-free operation in glovebox or biosafety cabinet environments
• Stainless steel enclosure (BT100F) with IP20-rated dust resistance for stable performance in general industrial laboratories

Sample Compatibility & Compliance

The BT-series accommodates a broad spectrum of tubing configurations, including standard Norprene®, PharMed® BPT, and custom-specified elastomers compliant with USP Class VI and FDA 21 CFR 177.2600. Flow calibration is traceable to NIST-traceable reference standards using gravimetric or volumetric verification methods per ISO 8599. While not certified for sterile processing, the pump’s tube-only fluid path meets ISO 13485-aligned design principles for medical device manufacturing support. All models operate within ambient conditions defined by IEC 61010-1:2010 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use), including overtemperature protection and reinforced insulation between control circuitry and motor drive stages.

Software & Data Management

No proprietary PC software is required for basic operation; however, full external control and data logging are enabled via MODBUS RTU over RS485. Integration with LabVIEW™, MATLAB®, or Python-based automation frameworks is supported through open register mapping documentation provided in the technical manual. The pump stores up to 100 programmable dispensing profiles locally, each with independent settings for speed ramping, dwell time, and post-dispense purge. All parameter changes, start/stop events, and error codes are timestamped and retained in an internal event log accessible via serial query—supporting 21 CFR Part 11-compliant audit trails when paired with validated third-party data acquisition systems.

Applications

• Automated reagent addition in clinical chemistry analyzers and immunoassay platforms
• Controlled feed of nutrients or inducers in microbial fermentation studies
• Calibration standard delivery in HPLC and IC systems requiring sub-milliliter repeatability
• Cell culture media exchange in adherent and suspension bioreactors (≤5 L working volume)
• Continuous sampling for online UV-Vis or conductivity monitoring loops
• Environmental water testing workflows involving sequential preservation agent dosing (e.g., HgCl₂, HNO₃)

FAQ

What tubing sizes are compatible with the YZ15 pump head?
The YZ15 head supports tubing IDs from 0.13 mm to 3.17 mm, including standard designations #13 through #18, with corresponding flow ranges spanning 0.0002–575 mL/min depending on rotational speed and wall thickness.
Can the pump be integrated into a PLC-controlled production line?
Yes—via isolated TTL-level digital I/O and analog 0–10 V / 4–20 mA inputs, plus RS485 MODBUS RTU, enabling seamless synchronization with Siemens S7, Allen-Bradley CompactLogix, or Beckhoff CX series controllers.
Is firmware update capability available?
Firmware upgrades are performed via USB-to-serial adapter using documented UART commands; version history and release notes are published on Chuding Tech’s official technical support portal.
Does the pump support bidirectional flow?
Yes—all models feature reversible motor control with programmable direction switching, allowing backflushing or recirculation configurations without mechanical re-piping.
How is calibration verified and maintained?
Users may perform in-house calibration using certified volumetric flasks or gravimetric balance methods; factory calibration certificates (traceable to national metrology institutes) are available upon request at time of purchase.
