Jipeng BT-100ST Digital Programmable Peristaltic Pump

Overview

The Jipeng BT-100ST Digital Programmable Peristaltic Pump is a precision-engineered fluid handling instrument designed for laboratory-scale applications requiring accurate, repeatable, and programmable liquid transfer. Based on the peristaltic principle—where rollers compress flexible tubing to generate positive displacement—the BT-100ST delivers pulse-minimized flow without fluid contact with mechanical components, ensuring contamination-free operation essential for sensitive biochemical, pharmaceutical, and analytical workflows. Its architecture integrates a high-resolution stepper motor with 256-microstep drive control, enabling smooth rotational motion across its full speed range (0.1–350 rpm), which directly translates into stable volumetric delivery across the specified flow range of 0.06–2290 mL/min. The pump is routinely deployed in modular chromatography systems, particularly when interfaced with UV/VIS nucleic acid and protein detectors or automated fraction collectors—enabling synchronized eluent delivery, real-time monitoring, and timed fraction collection under controlled flow conditions.

Key Features

• 4.5-inch HD capacitive touchscreen interface with intuitive Chinese-language menu navigation, displaying real-time flow rate, rotational speed, operational status, and elapsed time.
• Microstepping stepper motor (256 subdivisions per full step) ensures low-flow stability, minimal pulsation, and acoustic noise reduction—critical for low-volume sampling and gradient elution protocols.
• Titanium-alloy core housing and 316 stainless steel rollers provide enhanced corrosion resistance and extended service life when handling organic solvents, buffers, and mildly aggressive reagents.
• Non-volatile memory retains all user-defined parameters—including speed, timer settings, dispensing volume, and distribution cycles—after power interruption or shutdown.
• Dedicated full-speed mode (one-button activation) facilitates rapid tubing priming, system flushing, or emergency drainage without parameter reconfiguration.
• Onboard flow calibration function allows users to correct for tubing elasticity, wall thickness variation, and roller wear—improving long-term volumetric accuracy to ±0.5% (as verified against gravimetric or volumetric standards).
• External TTL-compatible control inputs enable hardware-level synchronization with fraction collectors or data acquisition systems—supporting event-triggered start/stop and interlock logic for GLP-compliant workflows.

Sample Compatibility & Compliance

The BT-100ST accommodates standard silicone or fluoropolymer-based peristaltic tubing sizes (#13 through #25), permitting compatibility with a broad spectrum of aqueous, polar, and moderately non-polar solutions. While not rated for high-pressure HPLC applications, it meets functional requirements for low-to-medium pressure liquid chromatography (e.g., gravity-fed or low-backpressure FPLC systems), preparative gel filtration, dialysis buffer exchange, and cell culture media perfusion. Its design adheres to IEC 61010-1 safety standards for laboratory electrical equipment. Though not certified for FDA 21 CFR Part 11 out-of-the-box, audit-ready operation is achievable via external logging software that captures timestamped parameter changes, operator IDs, and execution logs—facilitating GMP/GLP traceability when integrated into validated analytical platforms.

Software & Data Management

The BT-100ST operates as a standalone instrument with no proprietary PC software dependency; however, its external control interface supports integration into custom LabVIEW, Python, or MATLAB automation scripts via TTL-level digital I/O. All timing and dispensing parameters—including multi-stage programs with variable speed ramps, pause intervals, and looped distribution sequences—are configured directly on-device. Internal clock resolution supports millisecond-level timing fidelity for precise interval triggering. For regulated environments, users may implement third-party electronic lab notebook (ELN) systems to record pump configuration snapshots, calibration certificates, and usage logs—ensuring alignment with ISO/IEC 17025 documentation requirements for testing laboratories.

Applications

• Automated fraction collection in column chromatography (e.g., ion exchange, size exclusion, affinity purification).
• Controlled buffer delivery during electrophoresis buffer recirculation or Western blotting transfer steps.
• Time-scheduled reagent addition in enzymatic assays or kinetic studies.
• Continuous perfusion of bioreactors or microfluidic chips requiring stable, low-shear flow profiles.
• Calibration solution delivery in spectrophotometric or conductivity-based analyzers.
• Environmental water sampling systems where chemical inertness and field-deployable reliability are prioritized.

FAQ

Does the BT-100ST support bidirectional flow control?
Yes—the pump motor is fully reversible, allowing forward/reverse operation for backflushing, air bubble removal, or bidirectional fluid transfer protocols.
Can flow rate be calibrated for different tubing types?
Yes—built-in flow calibration mode enables user-defined correction factors based on gravimetric or volumetric measurement against a reference standard.
Is the touchscreen interface available in English?
No—the native firmware supports Chinese-language display only; however, all parameter labels and units conform to international conventions (mL/min, rpm, s, h), ensuring unambiguous interpretation.
What is the maximum operating pressure rating?
The pump head generates ≥3 kg/cm² (≈294 kPa) of occlusion pressure, sufficient for most low-backpressure chromatographic and general lab fluid transfer applications.
How is data integrity maintained during power loss?
All active parameters—including speed, timer values, dispensing volume, and distribution count—are retained in non-volatile memory and restored automatically upon reboot.
