Overview
The Acmer BT-600D is a high-precision distribution-mode peristaltic pump engineered for laboratory-scale liquid handling applications requiring repeatable volumetric dispensing, multi-step transfer protocols, and integration into automated workflows. Based on the positive displacement principle of peristalsis—where rollers compress an elastomeric tubing to sequentially occlude and propel fluid—the BT-600D delivers non-invasive, contamination-free fluid transport without valve wear or dead-volume accumulation. Unlike basic continuous-flow peristaltic pumps, the BT-600D implements advanced motion control algorithms that enable precise volume-based dispensing across wide dynamic ranges (0.0063–2600 mL/min), making it suitable for applications ranging from micro-liter reagent addition in analytical sample preparation to bulk buffer delivery in bioprocessing support systems.
Key Features
- Dual-Mode Operation: Supports both continuous transfer and discrete distribution modes—including time-based, volume-based, and count-based dispensing—with programmable start/stop logic.
- Multi-Point Calibration: Offers gravimetric, volumetric, and flow-rate calibration routines traceable to NIST-traceable standards; supports density-compensated mass dispensing via user-defined specific gravity inputs.
- Real-Time Parameter Adjustment: Enables live modification of dispense volume, flow rate, or number of cycles during operation—critical for method development and iterative protocol optimization.
- Comprehensive Status Feedback: Integrated digital outputs provide isolated TTL-level signals for Start/Stop, Rotation Direction, and Alarm conditions—facilitating seamless integration with PLCs, DAQ systems, or custom LabVIEW-based controllers.
- Leak Detection (Optional): Configurable optical/audible alert triggered by abnormal pressure decay or unexpected tubing deformation, supporting GLP-compliant process monitoring.
- Intuitive Human-Machine Interface: Backlit LCD display with contextual parameter guidance—e.g., real-time validation of achievable volume ranges based on selected tubing ID, speed, and target accuracy—reducing operator-induced error.
Sample Compatibility & Compliance
The BT-600D accommodates standard peristaltic pump tubing sizes from 0.5 mm to 16 mm inner diameter, compatible with silicone, Viton®, C-Flex®, and Pharmed® BPT materials—enabling chemical resistance across aqueous, organic, and mildly corrosive media. It complies with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) for electromagnetic compatibility in shared laboratory environments. While not certified for Class I Div 1 hazardous locations, its design adheres to general-purpose electrical safety requirements per UL 61010-1 and EN 61010-1. For regulated environments, the pump’s deterministic behavior, reproducible calibration logs, and external signal audit trail support alignment with FDA 21 CFR Part 11 data integrity expectations when paired with compliant software layers.
Software & Data Management
The BT-600D operates as a standalone instrument with embedded firmware supporting up to 16 user-defined programs stored in non-volatile memory. While no proprietary PC software is bundled, its standardized 5–24 V DC control interface enables direct integration with third-party platforms—including Python-controlled Raspberry Pi GPIO setups, National Instruments DAQmx sequences, or Beckhoff TwinCAT automation suites. All calibration records, run logs, and parameter configurations are retained internally with timestamped metadata. When connected to validated host software, the system supports electronic signature capture, change control tracking, and exportable CSV reports—meeting core documentation requirements under ISO/IEC 17025 and ASTM E2500 for analytical instrument qualification.
Applications
- Automated sample dilution and standard series preparation in environmental and pharmaceutical QC labs.
- Controlled reagent dosing in titration systems, enzymatic assays, and cell culture media supplementation.
- Buffer exchange and fraction collection in preparative chromatography support workflows.
- Continuous feed control in small-scale fermentation or perfusion bioreactor auxiliary systems.
- Integration into ISO 17025-accredited testing lines where traceability of dispense volume and timing is required for uncertainty budgeting.
FAQ
What tubing sizes are supported?
The BT-600D accepts tubing with inner diameters from 0.5 mm to 16 mm using interchangeable pump heads; recommended wall thickness is 0.8–1.6 mm for optimal occlusion and longevity.
Can the pump be used in GMP-regulated environments?
Yes—when deployed with documented calibration procedures, version-controlled firmware, and integrated into a validated software layer with audit trail capabilities, it meets foundational requirements for equipment qualification under EU Annex 11 and USP <1058>.
Is flow rate linearly proportional to rotational speed?
Within ±2% deviation across the full 0.0063–2600 mL/min range under stable backpressure (<100 kPa) and consistent tubing elasticity, provided tubing is properly seated and calibrated per manufacturer guidelines.
How is leak detection implemented?
Optional leak sensing relies on real-time motor current profiling and roller position deviation analysis—not pressure transducers—making it compatible with open-system dispensing while maintaining low false-positive rates.
Does the pump support bidirectional operation?
Yes—direction reversal is programmable and electrically isolated, enabling controlled backflushing or dual-reservoir cycling without mechanical reconfiguration.
