BT100S Constant Flow Peristaltic Pump

Overview

The BT100S Constant Flow Peristaltic Pump is a precision-engineered laboratory-grade peristaltic pump designed for reliable, repeatable, and contamination-free fluid handling in analytical, bioprocessing, and quality control environments. Operating on the principle of positive displacement via roller compression of flexible tubing, the BT100S delivers accurate volumetric flow without contact between the pump mechanism and the fluid—eliminating risk of cross-contamination, leakage, or seal degradation. Its digitally controlled DC motor drive ensures stable rotational output across the full speed range (0.1–150 rpm), enabling precise modulation of flow rates from ultra-low (0.00016 mL/min) to high-volume delivery (570 mL/min). The pump’s architecture integrates electromagnetic compatibility (EMC) hardening, dual-layer circuit isolation, and conformal coating on PCBs—ensuring robust operation under variable line voltage conditions and in electrically noisy industrial or shared-lab settings.

Key Features

• Four-digit LED display showing real-time speed value and operational mode (forward/reverse/run/stop/full-speed/clean)
• Optically isolated digital I/O for external start/stop, direction reversal, and simple dispensing triggers—compatible with footswitches, timers, PLCs, and HMI panels
• Analog speed control interface (0–5 V standard; 0–10 V or 4–20 mA optional) for seamless integration into analog-loop automation systems
• RS485 serial communication port supporting MODBUS RTU protocol for bidirectional parameter read/write, status monitoring, and remote scheduling
• Non-volatile memory retains last-used speed and mode settings after power loss (power-fail recovery)
• Stainless-steel enclosure rated IP31 for resistance to common laboratory solvents, weak acids, and alkaline solutions
• High-torque motor enables compatibility with multiple interchangeable pump heads—including multi-channel, low-pulse, and high-pressure configurations
• Adjustable speed resolution: 0.1 rpm at low-to-mid speeds (0.1–100 rpm); 1 rpm at upper range (100–150 rpm)
• Dual-stage electrical isolation and conformal-coated PCBs ensure long-term reliability in humid or particulate-prone environments

Sample Compatibility & Compliance

The BT100S is compatible with a broad range of elastomeric tubing materials—including silicone, Viton®, Tygon®, and Pharmapure®—enabling safe transfer of aqueous buffers, cell culture media, reagents, and mildly aggressive solvents. Its tube-based fluid path eliminates wetted metal parts, satisfying USP Class VI and ISO 10993 biocompatibility prerequisites for non-invasive applications. While not certified as medical device hardware, the pump meets general-purpose laboratory equipment requirements under IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and complies with EMC directives per EN 61326-1. Its MODBUS-enabled interface supports audit-ready process logging when integrated with SCADA or LIMS platforms compliant with FDA 21 CFR Part 11 data integrity guidelines.

Software & Data Management

The BT100S operates as a standalone instrument but is fully interoperable within automated workflows. Its native MODBUS RTU implementation allows direct integration with LabVIEW, MATLAB, Python (via PyModbus), and industrial PLCs (Siemens S7, Allen-Bradley, Mitsubishi) without proprietary drivers. Users can configure discrete commands (e.g., “start pump,” “set speed to 42.3 rpm,” “initiate 30-second dispense cycle”) and poll real-time status registers (e.g., actual speed, direction flag, fault codes). When deployed in GLP/GMP-regulated labs, the pump’s deterministic behavior—combined with external timestamped logging—supports traceability of fluid delivery events. Optional PC software (available upon request) provides GUI-based calibration, batch programming, and CSV export of operation logs for QA documentation.

Applications

• Automated sample introduction in HPLC, IC, and flow injection analysis (FIA) systems
• Continuous feeding of reagents or standards in titration and photometric analyzers
• Cell culture media perfusion and harvest in benchtop bioreactors
• Controlled dosing in chemical synthesis reactors and microfluidic platform priming
• Calibration solution delivery for conductivity, pH, and dissolved oxygen sensors
• Low-shear transfer of shear-sensitive biological suspensions (e.g., erythrocytes, microcarriers)
• Environmental water sampling stations requiring long-duration unattended operation

FAQ

What tubing sizes are supported by the BT100S?
The pump accommodates standard peristaltic tubing with inner diameters from 0.1 mm to 4.8 mm, depending on the installed pump head. Compatible head models include YZ15, YZ25, and DG series—each optimized for different flow ranges and pulse characteristics.
Does the BT100S support programmable dispensing cycles?
Yes—the “Simple Dispensing” function enables single-button initiation of timed liquid transfer. When combined with external timing devices or MODBUS commands, users can execute repeatable volume-based dispensing sequences with sub-second repeatability.
Can the pump be operated in hazardous or high-humidity areas?
The BT100S carries an IP31 ingress protection rating and conforms to IEC 61010-1 for laboratory use. It is suitable for indoor lab environments with ambient humidity <80% RH (non-condensing) but is not rated for explosive atmospheres or continuous outdoor exposure.
Is firmware upgrade capability available?
Firmware updates are performed via RS485 using vendor-provided utilities. Version history and update procedures are documented in the technical manual supplied with each unit.
What certifications does the BT100S hold?
The unit complies with CE marking requirements under the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU). It is not CE-marked as a medical device nor certified to ATEX or IECEx standards.
