Overview
The Hirschmann Rotarus® Flow is a high-precision peristaltic dispensing pump engineered for reproducible, traceable, and contamination-free liquid handling in regulated and research-intensive laboratory environments. Based on the principle of positive displacement via roller compression of elastomeric tubing, the Rotarus® Flow delivers accurate volumetric delivery without fluid contact with mechanical components—ensuring integrity for sensitive biological media, aggressive solvents, particulate-laden suspensions, and thermally unstable formulations. Its core architecture integrates real-time process monitoring with closed-loop control logic, enabling operation across a broad dynamic range (0.2–500 rpm) and flow rates up to 2000 mL/min—making it suitable for both low-volume precision dispensing and high-throughput transfer applications. Designed and manufactured in Germany under strict quality management systems (ISO 9001), the system meets fundamental requirements for GLP-compliant workflows and supports audit-ready documentation when integrated into validated environments.
Key Features
- Intelligent occlusion and leak detection: Built-in pressure and torque sensing algorithms identify tubing blockage or rupture during operation, triggering automatic shutdown and event logging.
- RFID-enabled pump head and tubing recognition: Each compatible pump head and tubing set carries a unique RFID tag; the system validates compatibility, records usage cycles, and prevents misconfiguration.
- Dual-mode control interface: Fully programmable via external 7-inch TFT touchscreen controller (with Ethernet/USB connectivity) or internal membrane keypad with OLED status display—supporting parameter locking, user-level access control, and multi-step method sequencing.
- Calibration traceability: Onboard calibration routine allows volume-based (mL/min) or speed-based (rpm) calibration against gravimetric or timed-collection reference standards; calibration data—including date, operator ID, and deviation values—is stored with timestamped metadata.
- Modular pump head design: Interchangeable pump heads accommodate tubing inner diameters from 0.5 mm to 13 mm, supporting viscosity ranges from water-like fluids to highly viscous gels (>10,000 mPa·s) and slurries containing particles up to 1 mm.
Sample Compatibility & Compliance
The Rotarus® Flow handles diverse sample types without cross-contamination risk: sterile culture media, antibiotic solutions, protein-rich buffers, acidic or alkaline reagents (pH 1–14), and abrasive suspensions. Tubing materials include platinum-cured silicone, Viton®, EPDM, and Tygon® formulations—each selected for chemical resistance, thermal stability (up to 120 °C continuous), and USP Class VI / FDA 21 CFR 177.2600 compliance. The system conforms to CE marking directives (2014/30/EU EMC, 2014/35/EU LVD), RoHS 2011/65/EU, and supports integration into ISO/IEC 17025-accredited testing laboratories. When used with validated methods and calibrated tubing, it satisfies critical parameters outlined in ASTM D1298 (density), ISO 8573-1 (compressed air purity), and USP Analytical Instrument Qualification.
Software & Data Management
The optional Rotarus® Control Software (v3.2+) provides PC-based configuration, remote monitoring, and electronic record generation compliant with 21 CFR Part 11 requirements—including role-based electronic signatures, audit trail activation, and immutable export of run logs (CSV/PDF). All calibration events, method executions, alarm histories, and RFID-read sessions are time-stamped and linked to operator credentials. Data export supports LIMS integration via OPC UA or RESTful API endpoints. Internal non-volatile memory retains ≥10,000 event entries with cyclic overwrite protection for critical fault conditions.
Applications
- Microbiology labs: Automated preparation of serial dilutions, agar pour plates, membrane filtration setups, and broth enrichment media dispensing.
- Pharmaceutical QC: Accurate delivery of dissolution media, buffer solutions, and extraction solvents in stability and release testing per ICH Q5C and USP .
- Food & cosmetic safety testing: Homogenized sample transfer for pathogen enrichment, preservative efficacy testing, and heavy metal digestion workflows.
- Industrial R&D: Metering of adhesives, sealants, and pigment dispersions in pilot-scale formulation trials; corrosion-resistant handling of pickling acids or electroplating baths.
- Environmental analysis: Low-particulate sampling of wastewater effluents, sediment pore water extraction, and field-deployable filtration support.
FAQ
Does the Rotarus® Flow support GLP-compliant calibration documentation?
Yes—calibration records include operator ID, reference standard traceability, environmental conditions, pass/fail status, and digital signature fields aligned with OECD GLP Principles.
Can the pump be integrated into an automated liquid handling platform?
Yes—it offers RS-232, USB Device, and Ethernet interfaces with ASCII command protocol and Modbus TCP support for OEM integration.
Is tubing lifetime tracked automatically?
Yes—RFID-tagged tubing sets log cumulative rotation count and thermal exposure history; alerts trigger at 80% of manufacturer-specified service life.
What validation documentation is provided with the instrument?
Each unit ships with Factory Acceptance Test (FAT) report, IQ/OQ templates, and a Certificate of Conformance referencing DIN EN ISO 9001:2015 manufacturing controls.
How is accuracy maintained across varying viscosities?
The system applies dynamic speed compensation using preloaded viscosity-flow correlation curves; users may define custom compensation profiles based on Newtonian or shear-thinning behavior.
