Acmer BT-600U Precision Peristaltic Pump

Overview

The Acmer BT-600U Precision Peristaltic Pump is an industrial-grade laboratory peristaltic pump engineered for high-accuracy fluid transfer across demanding analytical, bioprocessing, and quality control workflows. Based on the positive displacement principle of peristalsis—where rollers compress a flexible tubing segment against a curved housing to generate unidirectional flow—the BT-600U delivers pulse-free, contamination-free, and shear-sensitive fluid handling without valve or seal contact. Its wide dynamic flow range (0.0063–2600 mL/min) and fine speed resolution (0.1 rpm increments) support applications from nanoliter-scale reagent dosing in HPLC sample introduction to bulk media circulation in bioreactor feed systems. The pump’s modular architecture accommodates multiple interchangeable pump heads—including YZ1513, YZ2513S, BZ, and DMD1513—enabling rapid adaptation to tubing inner diameters from 0.1 mm to 16 mm and corresponding flow/pressure requirements.

Key Features

• Multi-Head Compatibility: Supports standardized pump heads (YZ1513, YZ2513S, BZ, DMD1513) for seamless tubing diameter and flow profile optimization.
• Full-Speed & Fine-Speed Modes: Dual operational modes—“Full Speed” for rapid priming or line purging, and “Adjustable Speed” with 0.1 rpm resolution for precise volumetric delivery.
• Intuitive Local Interface: Backlit LCD display shows real-time rotational speed, direction indicator (CW/CCW), run/pause status, and system error codes.
• Configurable Speed Limitation: User-defined maximum RPM setting prevents unintentional over-speed operation; enforced at firmware level regardless of control source.
• Robust Control Flexibility: Native support for local keypad, footswitch actuation, 0–5 V / 0–10 V / 4–20 mA analog input, TTL digital start/stop, and RS485 Modbus RTU protocol for integration into SCADA, LIMS, or PLC-based automation environments.
• Operational Safeguards: Keypad lock function (via key combination) disables parameter modification during continuous operation; optional leak detection module triggers configurable responses (e.g., immediate stop, alarm output, relay activation) upon fluid presence detection beneath the pump head.

Sample Compatibility & Compliance

The BT-600U is compatible with all commercially available peristaltic pump tubing materials certified for laboratory use—including silicone, Viton®, Tygon® LFL, PharMed® BPT, and C-Flex®—ensuring chemical resistance and compliance with USP Class VI, FDA 21 CFR 177.2600, and EU Regulation (EC) No. 1935/2004 for food-contact applications. While the pump itself does not carry CE or UL certification as a standalone device, its electrical design conforms to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards when installed per manufacturer guidelines. When integrated into GxP-regulated processes, the pump supports audit-ready operation through Modbus event logging and external PLC timestamping—facilitating alignment with GLP and GMP documentation requirements for traceability and change control.

Software & Data Management

No proprietary software is required for basic operation; however, the RS485 Modbus RTU interface enables full remote parameterization and monitoring via industry-standard Modbus master applications (e.g., ModScan, QModMaster) or custom LabVIEW, Python (pymodbus), or MATLAB implementations. All operational states—including setpoint RPM, actual RPM, direction, run time, and fault events—are register-mapped for real-time polling and historical trending. For regulated environments, data integrity is reinforced by write-protected configuration registers and timestamped command logs when interfaced with validated supervisory systems compliant with FDA 21 CFR Part 11 electronic record requirements.

Applications

• Automated liquid handling in pharmaceutical QC labs (e.g., dissolution testing, buffer exchange in protein purification).
• Continuous feeding of nutrient or inducer solutions in microbial fermentation and mammalian cell culture platforms.
• Low-shear transfer of shear-thinning biologics (e.g., monoclonal antibodies, viral vectors) where particle integrity must be preserved.
• Integration into inline process analyzers (e.g., UV-Vis flow cells, conductivity sensors) requiring stable, pulsation-damped flow.
• Environmental water analysis systems for sequential injection of standards, samples, and reagents in EPA Method-compliant analyzers.

FAQ

What tubing sizes are supported by the BT-600U?
The pump accommodates tubing inner diameters from 0.1 mm to 16 mm depending on the installed pump head—YZ1513 (0.1–4.8 mm), YZ2513S (0.5–9.6 mm), BZ (1.6–13 mm), and DMD1513 (up to 16 mm ID).
Is the pump suitable for sterile or aseptic applications?
Yes—when paired with gamma-sterilizable tubing (e.g., PharMed BPT, C-Flex) and operated within validated parameters, the BT-600U supports aseptic fluid transfer in ISO Class 5 environments; tubing replacement is tool-free and operator-intervention minimal.
Can the leak detection module be retrofitted to existing units?
Yes—the optional leak sensor kit (model LD-KIT-BT600) includes mounting hardware, optical sensor, and firmware update; installation requires no disassembly of the main drive unit.
Does the pump support flow calibration or volumetric accuracy verification?
While the BT-600U is calibrated for rotational speed—not volumetric flow—users may perform gravimetric or timed-collected volume validation per ASTM D3418 or ISO 8504-2; recommended calibration frequency is quarterly or after tubing replacement.
How is firmware updated?
Firmware updates are delivered via RS485 using Acmer’s official configuration utility (Windows-only); update files and procedures are provided under NDA to authorized distributors and end-users with service contracts.
