ROCKER Buller600 Precision Dispensing Peristaltic Pump

Overview

The ROCKER Buller600 is a high-precision, single-channel dispensing peristaltic pump engineered for reproducible, contamination-free liquid handling in regulated laboratory environments. It operates on the fundamental principle of peristalsis—where rollers compress flexible tubing to generate positive displacement flow—ensuring zero fluid contact with mechanical components and eliminating cross-contamination risks. Designed specifically for microbiological workflows, the Buller600 integrates pre-programmed volume protocols aligned with standard culture vessel geometries and regulatory expectations for sample preparation in clinical, pharmaceutical, and food safety testing labs. Its robust architecture supports continuous operation under GLP-compliant conditions, with traceable parameter settings and audit-ready control logic.

Key Features

• 5-inch capacitive touchscreen interface with intuitive graphical navigation and multilingual support (English, Spanish, German, Chinese)
• Digital speed control across 1–600 rpm with ±1% volumetric accuracy over full flow range (up to 1950 mL/min using standard pump head)
• Extended timer function supporting durations from 1 second to 999 hours, 59 minutes, 59 seconds—enabling unattended overnight dispensing or long-term perfusion applications
• Ergonomic handheld dispenser with magnetic docking station for rapid attachment/detachment; compatible with autoclave sterilization (121°C, 15 psi, 20 min)
• Predefined microbiology dispensing modes: tube (2.5 / 5 / 9 mL), Petri dish (15 / 18 / 20 mL), and serum bottle (90 / 225 / 450 mL) volumes—reducing operator input errors and protocol deviation
• Aspirate-back functionality minimizes drip and residual droplet formation, improving volumetric repeatability especially at low dispense volumes (1–10 mL)
• RS-232 serial interface enables bidirectional communication with LIMS, ELN, or custom automation systems for integration into ISO 17025 or FDA 21 CFR Part 11 compliant workflows

Sample Compatibility & Compliance

The Buller600 accommodates a broad spectrum of tubing materials certified for pharmaceutical and diagnostic use—including Tygon S3™ E3603 (USP Class VI), PHARMED® BPT (FDA-compliant), and Biosicon silicone formulations—each available in multiple inner diameters (ID #16, #17, #25) to optimize flow profile and pulse dampening. All tubing options are validated for repeated autoclaving without degradation in elasticity or chemical resistance. The pump meets IEC 61010-1 safety standards for laboratory equipment and complies with electromagnetic compatibility (EMC) requirements per EN 61326-1. Its operational design aligns with ISO 8573-1 (compressed air purity) and USP guidelines for liquid handling system qualification in biopharmaceutical manufacturing.

Software & Data Management

While the Buller600 operates as a standalone instrument, its RS-232 port allows seamless integration with external data acquisition platforms. Command protocols follow ASCII-based SCPI-like syntax, supporting remote initiation/termination of runs, real-time speed readback, elapsed time reporting, and error code logging. When deployed in GxP environments, users may configure external software (e.g., LabVIEW, Python scripts, or commercial LIMS modules) to capture timestamped dispensing events—including volume, speed, duration, and user ID—for electronic record retention. Audit trails can be generated to satisfy ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) required under FDA 21 CFR Part 11 and EU Annex 11.

Applications

• Microbiological sample preparation: accurate inoculation of agar plates, broth dilutions, and membrane filtration support fluids
• Pharmaceutical QC/QA: buffer and reagent dispensing for dissolution testing, stability studies, and microbial limit assays per USP , , and
• Biotechnology: media filling for shake flasks and bioreactor seed trains; consistent transfer of sensitive cell suspensions without shear-induced lysis
• Clinical diagnostics: standardized distribution of calibrators, controls, and patient specimens across automated assay platforms
• Academic research: programmable gradient delivery in enzymatic kinetics, chromatography solvent management, and microfluidic priming protocols

FAQ

Is the Buller600 suitable for sterile processing environments?
Yes—the handheld dispenser, dispensing needle, and all compatible tubing types are autoclavable and chemically resistant to common sterilants including hydrogen peroxide vapor and ethylene oxide.
Can the pump be validated for use in regulated pharmaceutical manufacturing?
Yes—its digital control architecture, RS-232 traceability, and compliance with IEC 61010-1 and USP make it suitable for IQ/OQ/PQ execution within GMP frameworks.
What tubing sizes are supported, and how do they affect flow performance?
The Buller600 accepts tubing with inner diameters of #16 (1.6 mm), #17 (2.4 mm), and #25 (3.2 mm). Larger IDs increase maximum flow rate but reduce precision at low volumes; selection should balance throughput requirements against volumetric tolerance needs.
Does the pump support footswitch operation for hands-free dispensing?
Yes—a DB9-compatible footswitch (model 185600-41) is available as an optional accessory for ergonomic, repeatable actuation during high-throughput workflows.
How is calibration performed, and is it traceable to national standards?
Calibration is performed gravimetrically using certified analytical balances per ASTM E2877-21. ROCKER provides calibration certificates with NIST-traceable references upon request, valid for 12 months under normal operating conditions.
