Hirschmann rotarus® Stand Holder for Peristaltic Pumps

Overview

The Hirschmann rotarus® Stand Holder is a precision-engineered mechanical support system designed specifically for laboratory-grade peristaltic pumps. It functions as a rigid, height-adjustable mounting platform that ensures stable, vibration-dampened positioning of peristaltic pump heads during continuous or intermittent fluid transfer operations. Unlike generic lab clamps or universal stands, the rotarus® Stand Holder integrates ergonomic design with metrological stability—its geometry is optimized to align pump rollers, tubing paths, and drive shafts within tight angular tolerances (±0.5°), minimizing torsional stress on pump tubing and preserving flow accuracy over extended duty cycles. Developed in accordance with DIN 12878 and ISO 8573-1 clean air compatibility guidelines, the stand is constructed from anodized aluminum alloy (EN AW-6063-T5) with stainless steel fasteners (A2-70), ensuring corrosion resistance in humid or solvent-exposed environments typical of analytical labs, bioprocessing suites, and quality control facilities.

Key Features

• Modular vertical adjustment via dual M10 fine-thread spindles (0.5 mm pitch), enabling precise height calibration from 220 mm to 480 mm above bench surface
• Integrated anti-rotation locking mechanism prevents lateral drift during pump operation at speeds up to 600 rpm
• Quick-release pump head cradle with three-point contact geometry—designed to accommodate standard Hirschmann rotarus® pump heads (e.g., rotarus® 100, rotarus® 200 series) without tooling
• Non-slip base plate (180 × 120 mm footprint) with integrated leveling feet and optional vacuum pad interface for high-stability mounting on laminar flow hoods or shaker tables
• CE-marked and compliant with EN 61000-6-2 (immunity) and EN 61000-6-4 (emission) electromagnetic compatibility standards

Sample Compatibility & Compliance

The rotarus® Stand Holder does not directly interact with samples but serves as a critical mechanical interface between peristaltic pump hardware and laboratory infrastructure. Its structural rigidity supports tubing diameters ranging from 0.5 mm to 6.4 mm (ID), compatible with silicone, Viton®, and PharMed® BPT peristaltic tubing used in USP -compliant applications. The stand’s material composition meets EU Regulation (EC) No 1935/2004 for materials intended to come into contact with foodstuffs, and its surface finish (Ra ≤ 0.8 µm) facilitates cleaning validation under GMP Annex 1 and ISO 14644-1 Class 5 cleanroom protocols. Documentation includes full traceable material certificates (3.1 according to EN 10204) and RoHS 2011/65/EU conformity declaration.

Software & Data Management

As a purely mechanical mounting solution, the rotarus® Stand Holder requires no embedded firmware, drivers, or software integration. However, it is fully interoperable with Hirschmann’s digital pump control ecosystem—including the rotarus® Control Software v4.x and LabSolutions™ middleware—enabling synchronized setup of pump parameters (flow rate, direction, ramp profiles) while maintaining mechanical integrity across automated liquid handling workflows. Audit trails generated by connected pump controllers remain unaffected by stand installation; all mechanical adjustments are manually recorded in lab notebooks per GLP requirements (OECD Principles of Good Laboratory Practice, Section 1.3.1). Calibration records for pump performance verification (e.g., gravimetric flow rate checks per ASTM D3417) may reference stand positioning as a controlled variable.

Applications

• Continuous feed systems in HPLC and IC mobile phase delivery, where mechanical resonance can induce baseline noise or pressure fluctuations
• Cell culture media perfusion setups requiring uninterrupted flow over 72+ hour intervals under ISO 5 biosafety cabinets
• Automated titration modules in potentiometric and photometric analyzers (e.g., Metrohm 916 Ti-Touch), where pump alignment affects reagent dosing repeatability
• Environmental water analysis workflows involving EPA Method 300.0–compliant ion chromatography, where tubing fatigue must be minimized during multi-day unattended runs
• Pharmaceutical formulation development using peristaltic pumps for excipient blending, aligned to ICH Q5C stability protocol mechanical constraints

FAQ

Is the rotarus® Stand Holder compatible with non-Hirschmann peristaltic pumps?
Yes—provided the pump head features standardized M6 mounting holes on a 40 mm × 40 mm pitch grid and weighs ≤ 3.2 kg. Mechanical fit verification is recommended prior to operational deployment.
Does the stand include tubing routing guides or strain relief components?
No—tubing management is handled separately via Hirschmann’s rotarus® Tube Guide Kit (Order No. 900 123), which mounts directly onto the stand’s rear support rail.
Can the stand be sterilized using autoclaving or VHP (vaporized hydrogen peroxide)?
Autoclaving is not recommended due to thermal expansion mismatch between aluminum and stainless steel components; however, the stand is fully compatible with VHP decontamination cycles (≤ 1000 ppm, 60% RH, 25–30°C) per ISO 14644-3 Annex C.2.
What documentation is supplied with each unit?
Each shipment includes a Declaration of Conformity (DoC), material test report (MTR), dimensional drawing (PDF + STEP), and installation checklist aligned with ISO/IEC 17025 clause 6.4.1.
