Acmer BT-600B Precision Peristaltic Pump

Overview

The Acmer BT-600B 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 a flexible tubing segment against a curved housing to generate positive displacement—the BT-600B delivers precise volumetric flow without exposing internal components to the fluid path. This design eliminates risk of cross-contamination, avoids seal degradation, and ensures compatibility with aggressive solvents, viscous suspensions, shear-sensitive biomolecules, and particulate-laden media. Its wide dynamic flow range (0.0063–2600 mL/min) and fine speed resolution support applications from microfluidic reagent dosing to high-throughput buffer exchange, making it suitable for integration into automated liquid handling platforms, chromatography systems, fermentation feed lines, and environmental sampling rigs.

Key Features

• Multi-Head Compatibility: Supports interchangeable pump heads—including YZ1513 (for 0.1–10 mL/min), YZ2513S (for 0.5–60 mL/min), BZ (for 1–300 mL/min), and DMD1513 (for high-torque, low-pulse operation)—enabling optimized performance across viscosity, pressure, and accuracy requirements.
• Full-Speed & Fine-Resolution Control: Delivers rapid priming and system purge via full-speed mode; supports manual speed adjustment from 0.1 to 600 rpm in 0.1-rpm increments for repeatable low-flow delivery.
• Dual Control Architecture: Combines intuitive front-panel keypad operation with external analog (0–5 V DC, 4–20 mA) and digital (TTL-level) inputs for seamless integration into PLC-controlled or PC-based automation systems.
• Real-Time Operational Feedback: Integrated LCD displays current rotational speed, direction indicator (CW/CCW), run/pause status, and error codes—enabling immediate verification during method execution.
• Configurable Safety Limits: User-defined maximum speed limit prevents accidental over-speed operation; keyboard lock function secures parameter settings against unintended modification during unattended runs.
• Robust Mechanical Design: Features precision-machined stainless-steel rotor, hardened roller bearings, and thermally stable housing—ensuring long-term repeatability and minimal pulse variation (<±2% CV at steady state).

Sample Compatibility & Compliance

The BT-600B maintains full fluid path isolation—only the tubing contacts the sample—making it compatible with aqueous buffers, organic solvents (e.g., acetonitrile, methanol), cell culture media, enzyme solutions, and abrasive slurries when paired with chemically resistant tubing (e.g., PharMed® BPT, Viton®, or silicone). It complies with general laboratory safety standards (IEC 61010-1) and supports GLP/GMP-aligned workflows through traceable operational parameters and configurable audit logs (when integrated with compliant SCADA or LIMS software). While not certified for medical device use, its performance aligns with ASTM D4767 (for controlled fluid transfer in material testing) and ISO 8573-1 (for clean air and fluid handling in controlled environments).

Software & Data Management

The pump operates autonomously via its embedded firmware but supports external command protocols for data synchronization. When interfaced with host software (e.g., LabVIEW, Python-based control scripts, or custom HMI), real-time RPM, direction, and status signals can be logged alongside process timestamps. Optional RS-485 or USB-to-serial adapters enable bidirectional communication for remote start/stop, speed ramping, and fault reporting. All configuration changes—including max speed limits and keypad lock states—are retained in non-volatile memory. For regulated environments, integration with 21 CFR Part 11–compliant software platforms allows electronic signature capture, user access control, and immutable audit trail generation.

Applications

• Continuous feeding of nutrient media in microbial or mammalian cell bioreactors
• Accurate delivery of calibration standards and QC samples in ICP-MS, HPLC, and ion chromatography systems
• Controlled eluent addition in automated solid-phase extraction (SPE) workstations
• Low-shear transfer of fragile liposomes, exosomes, or protein aggregates
• Environmental water sampling with integrated filtration and preservation reagent injection
• In-line pH or conductivity probe calibration using standardized buffer streams

FAQ

What tubing sizes are supported by the BT-600B?
The pump accommodates tubing inner diameters from 0.1 mm to 6.4 mm, depending on the installed pump head—YZ1513 accepts 0.1–2.4 mm ID, while DMD1513 supports up to 6.4 mm ID tubing.
Can the BT-600B operate under backpressure?
Yes—it sustains continuous flow under up to 2 bar static backpressure when used with reinforced tubing and appropriate pump head selection; performance validation is recommended for each specific fluid/tubing combination.
Is firmware upgrade capability available?
Firmware updates are provided by Acmer upon request and require a dedicated programming interface; version history and release notes are documented in the technical support portal.
How is calibration verified?
Flow accuracy is validated gravimetrically per ISO 8655-4 using certified balances and temperature-controlled collection vessels; Acmer provides factory calibration certificates traceable to NIM (China National Institute of Metrology).
Does the pump meet electromagnetic compatibility (EMC) requirements?
It conforms to EN 61326-1 for laboratory equipment, including emission limits (EN 55011) and immunity thresholds (IEC 61000-4 series) applicable to industrial environments.
