Overview
The Acmer BT-300B Precision Peristaltic Pump is an engineered solution for accurate, contamination-free fluid handling in analytical laboratories, bioprocessing workflows, and quality control environments. Based on the peristaltic principle—where rollers compress flexible tubing to generate positive displacement—the BT-300B ensures complete fluid isolation from pump mechanics, eliminating risk of cross-contamination or seal degradation. Its design prioritizes reproducibility and long-term stability under continuous operation, making it suitable for applications requiring precise volumetric delivery across wide flow ranges—from microliter-per-minute dosing in HPLC mobile phase delivery to high-throughput media transfer in cell culture systems.
Key Features
- Wide Dynamic Flow Range: Delivers 0.0063 mL/min to 1490 mL/min with consistent linearity and repeatability, enabled by precision-machined roller geometry and calibrated stepper motor control.
- Multi-Head Compatibility: Supports interchangeable pump heads including YZ1513 (for 0.1–10 mL/min), YZ2513S (for 1–100 mL/min), BZ (for high-torque, low-speed viscous fluids), and DMD1513 (for dual-channel parallel operation), allowing configuration flexibility without hardware replacement.
- Dual-Mode Speed Control: Offers both manual adjustment via intuitive front-panel keypad and external analog/digital interface support (0–5 V, 0–10 V, 4–20 mA, TTL), enabling seamless integration into PLC-controlled or SCADA-monitored laboratory automation systems.
- Real-Time Operational Feedback: Integrated LCD displays current rotational speed (rpm), direction indicator (CW/CCW), and status flags (Run, Stop, Pause, Error), supporting immediate verification during method execution.
- Configurable Safety Limits: User-defined maximum speed limit prevents accidental over-speed operation; keypad lock function (activated via three-key sequence) secures parameter settings against unintended modification during unattended runs.
- Bidirectional Operation: Reversible rotation enables purge cycles, backflushing of inline filters, and recirculation protocols critical in closed-loop sampling or calibration procedures.
Sample Compatibility & Compliance
The BT-300B accommodates standard silicone, Viton®, and PharmPure® tubing (ID 0.1–6.4 mm), supporting compatibility with aqueous buffers, organic solvents, cell suspensions, and mildly corrosive reagents. While not certified for ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its deterministic flow behavior, traceable speed calibration, and audit-ready operational logs (when paired with compatible data acquisition software) align with GLP and GMP documentation requirements for non-critical process steps. It meets IEC 61000-6-3 (EMC emission) and IEC 61000-6-2 (immunity) standards for laboratory-grade electrical equipment.
Software & Data Management
The pump operates autonomously via front-panel controls but supports optional RS485 Modbus RTU communication for integration with LabVIEW™, MATLAB®, or custom SCADA platforms. When connected to Acmer’s optional PC-based control suite (v3.2+), users gain access to time-stamped run logs, programmable multi-step profiles (e.g., ramp-up → hold → ramp-down), and exportable CSV reports compliant with internal QA record retention policies. Audit trails include operator ID, timestamp, setpoint changes, and fault codes—facilitating root-cause analysis during process validation.
Applications
- Automated sample introduction in atomic absorption spectroscopy (AAS) and inductively coupled plasma (ICP) systems
- Continuous feed of nutrient media or harvest buffer in benchtop bioreactors and perfusion cultures
- Controlled reagent addition in titration and kinetic assay platforms
- Low-shear transfer of shear-sensitive biologicals (e.g., exosomes, viral vectors)
- Calibration fluid delivery in flow cytometry and particle counting instrumentation
- Mobile phase delivery in preparative chromatography where solvent compatibility and pulseless flow are essential
FAQ
What tubing sizes are supported by the BT-300B?
The pump accommodates tubing inner diameters from 0.1 mm to 6.4 mm, depending on the installed head—YZ1513 supports 0.1–2.4 mm, YZ2513S supports 0.5–6.4 mm, and BZ/DMD1513 support specialized high-pressure or dual-channel configurations.
Can the BT-300B be integrated into a LIMS or ELN environment?
Yes—via RS485 Modbus RTU or analog/digital I/O, the pump can transmit real-time status and accept remote commands; full LIMS integration requires middleware configuration to map pump events to audit-compliant metadata fields.
Is calibration traceability available?
Acmer provides factory calibration certificates (NIST-traceable reference flow meters) upon request; users may perform in-house verification using gravimetric or timed-volume methods per ASTM D3417 or ISO 8504-2.
Does the pump support continuous duty cycle operation?
Yes—the BT-300B is rated for 24/7 operation at ≤80% of max speed under ambient temperatures up to 40°C and relative humidity ≤80% non-condensing, with thermal protection circuitry preventing motor overheating.
