Overview
The BT100-4 Four-Channel Digital Constant-Flow Peristaltic Pump is a precision-engineered laboratory fluid handling instrument designed for simultaneous, independent delivery of multiple reagents, solvents, or biological media under controlled volumetric flow conditions. Based on the proven principle of peristaltic pumping—where rollers compress flexible tubing to generate positive displacement—the BT100-4 eliminates fluid contact with mechanical components, ensuring contamination-free operation and chemical compatibility across a broad range of aqueous, organic, and mildly corrosive solutions. Its microprocessor-controlled stepper motors deliver high reproducibility in flow rate across all four channels, making it suitable for applications requiring synchronized yet individually adjustable dosing sequences, such as multi-stream chromatography sample introduction, parallel bioreactor feed control, or sequential reagent addition in automated synthesis workflows.
Key Features
- Four independent peristaltic pump heads, each with dedicated digital RPM display and rotary encoder adjustment for precise speed control (0.1–100 rpm typical range, corresponding to 0.3–5000 mL/h per channel with standard 16# silicone tubing)
- Robust aluminum alloy chassis with compact footprint (120 × 270 × 120 mm), optimized for benchtop integration in fume hoods, biosafety cabinets, or modular lab automation setups
- Non-invasive fluid path: only tubing contacts the liquid—enabling rapid changeover between incompatible chemistries without cross-contamination risk
- Overload protection and stall detection circuitry prevent motor damage during tubing occlusion or excessive back pressure (rated ≥2.5 kg/cm² at full speed)
- Front-panel keypad interface with real-time RPM readout per channel; no PC required for basic operation
- Standard 1/4″–3/8″ tubing compatibility (e.g., PharMed® BPT, Norprene®, or silicone); optional tube clamps support quick-release tube replacement
Sample Compatibility & Compliance
The BT100-4 accommodates a wide spectrum of laboratory fluids—including cell culture media, buffer solutions, enzyme substrates, polymer precursors, and low-viscosity organic solvents—provided tubing material is selected accordingly. It complies with general electrical safety requirements per IEC 61010-1 for laboratory equipment. While not certified for intrinsically safe or explosion-proof environments, its design supports GLP-aligned documentation practices when used with traceable calibration records and maintenance logs. For regulated pharmaceutical manufacturing (e.g., USP Analytical Instrument Qualification), users may implement IQ/OQ protocols covering flow accuracy verification (±2% typical at mid-range flow), channel-to-channel synchronization tolerance (<±0.5 rpm), and long-term stability testing over 8-hour continuous operation.
Software & Data Management
The BT100-4 operates as a standalone instrument but supports RS-232 serial communication (optional TTL-to-USB adapter) for remote command control via ASCII-based protocol (e.g., “S1=35” sets Channel 1 speed to 35 rpm). Third-party software integration—including LabVIEW™, MATLAB®, and Python (pySerial) environments—is documented in the technical manual. Audit trail functionality is not embedded natively; however, external data acquisition systems can log timestamped RPM commands and status flags (e.g., run/pause/error) to satisfy FDA 21 CFR Part 11 requirements when paired with appropriate electronic signature and access control layers.
Applications
- Parallel feeding of nutrient streams in multi-vessel microbial fermentation systems
- Sequential eluent delivery in preparative HPLC or ion chromatography gradient methods
- Controlled reagent injection in continuous-flow microreactors and lab-on-chip platforms
- Automated sampling and dilution in environmental water analysis (e.g., EPA Method 300.0 compliance support)
- Cell perfusion in hollow-fiber bioreactors and organ-on-chip models requiring pulsation-free flow
- Calibration solution delivery in multi-parameter water quality analyzers (pH, conductivity, DO)
FAQ
What tubing sizes are recommended for optimal flow accuracy and longevity?
Standard operation uses 16# (ID 1.6 mm) silicone or PharMed® BPT tubing. For higher flow rates (>3000 mL/h), 19# (ID 3.2 mm) tubing may be employed—though maximum pressure rating decreases proportionally.
Can the BT100-4 maintain consistent flow under variable downstream resistance?
Yes—its constant-RPM architecture ensures volumetric consistency within ±2% across the specified back pressure range (≤2.5 kg/cm²), provided tubing elasticity and roller compression remain stable.
Is firmware upgradable in the field?
No—firmware is固化 (flash-locked) at manufacture; functional updates are implemented via hardware revision (e.g., BT100-4 v2.1 introduces enhanced thermal management).
Does the pump meet ISO 8573-1 Class 0 air purity requirements?
Not applicable—the BT100-4 is a liquid-handling device with no compressed air interface; ISO 8573-1 pertains exclusively to pneumatic systems.
What is the expected service life of the drive rollers and tubing under continuous operation?
With proper tension adjustment and 24/7 use at 50 rpm, rollers typically exceed 10,000 hours MTBF; tubing lifespan ranges from 100–500 hours depending on chemical exposure and flow rate.
