IKA ROTAVISC hi-vi II HELI Complete Rotational Viscometer

Overview

The IKA ROTAVISC hi-vi II HELI Complete is a high-precision benchtop rotational viscometer engineered for reliable, reproducible viscosity characterization of highly viscous and non-Newtonian fluids across R&D laboratories, QC/QA environments, and industrial process development settings. Based on the Couette principle—where torque exerted on a rotating spindle immersed in a sample is measured under controlled shear rate—the instrument delivers quantitative rheological data essential for formulation optimization, stability assessment, and regulatory documentation. Its extended viscosity range (800–320,000,000 mPa·s) enables direct measurement of materials such as polymer melts, bitumen, heavy lubricants, pastes, gels, and thermosetting resins without dilution or pre-shearing. The integrated HELISTAND motorized lift system ensures consistent immersion depth and vertical alignment, minimizing boundary effects and operator-induced variability—critical for GLP-compliant reporting and ASTM D2196/D1092 method adherence.

Key Features

• Motorized HELISTAND升降支架 with 142 mm total travel and 61 mm active stroke, enabling precise, repeatable spindle immersion at programmable speeds
• 4.3″ full-color TFT touchscreen interface with intuitive menu navigation, real-time graphical display (viscosity vs. time, shear rate, or temperature), and built-in electronic level for rapid horizontal alignment
• Continuous speed control from 0.01 to 200 rpm with ±0.01 rpm resolution and ramp profiling (RAMP function) for standardized shear history application
• High-torque measurement capability (up to 5.7496 mN·m) with ±1% full-scale accuracy and ±0.2% full-scale repeatability per ISO 2555 and ASTM D1824
• Integrated PT100 temperature sensor port supporting external cryo- or high-temperature baths; compatible with IKA’s TC-3 temperature controller for dynamic thermal profiling
• Comprehensive safety architecture including overload protection, automatic shutdown on motor stall, and IP40-rated enclosure for laboratory-grade environmental resilience

Sample Compatibility & Compliance

The ROTAVISC hi-vi II HELI Complete accommodates a broad spectrum of sample geometries and physical states—including opaque suspensions, fiber-reinforced composites, and thermally sensitive formulations—via its modular SP7–SP12 spindle set and optional T-spindle configuration. The standard 600 mL vessel compatibility supports ASTM D1200 and ISO 2555 compliant testing protocols. All measurements adhere to internationally recognized standards for rotational viscometry, including ISO 3219 (rotational viscometers), ASTM D445 (kinematic viscosity reference correlation), and USP (rheological characterization of pharmaceutical semisolids). Data integrity meets FDA 21 CFR Part 11 requirements when paired with IKA LabWorldSoft™ v4.x software, providing audit-trail-enabled user authentication, electronic signatures, and secure data archiving.

Software & Data Management

IKA LabWorldSoft™ (v4.3+) provides full instrument control, method scripting, multi-parameter logging (viscosity, torque, temperature, time), and export-ready reporting in CSV, PDF, and XML formats. The software supports automated calibration verification using NIST-traceable standard oils, batch-level metadata tagging (operator ID, lot number, SOP version), and trend analysis across historical datasets. Raw data files are stored with immutable timestamps and checksum validation. USB and RS-232 interfaces enable seamless integration into LIMS environments and centralized instrument management platforms. All firmware updates are digitally signed and delivered via IKA’s secure support portal.

Applications

• Quality control of adhesives, sealants, and coatings where yield stress and thixotropic recovery must be quantified per ISO 10420
• Rheological screening of battery electrode slurries and ceramic pastes during formulation development
• Thermal stability assessment of heat-transfer fluids and synthetic lubricants across −100 °C to +300 °C
• Viscoelastic profiling of food gels (e.g., starch-based systems, dairy analogs) under controlled shear ramping
• Validation of curing kinetics in epoxy and polyurethane resin systems using time-temperature-viscosity correlations
• Regulatory submission support for FDA, EMA, and PMDA dossiers requiring documented measurement uncertainty and traceable calibration records

FAQ

What spindle configurations are included with the ROTAVISC hi-vi II HELI Complete?
The system ships with the SP7–SP12 standard spindle set, a T-type spindle kit, rotor guard stand, and integrated PT100 temperature probe.
Can the instrument perform temperature-controlled measurements below 0 °C?
Yes—when connected to an external cryostat and PT100-compatible bath, it supports measurements down to −100 °C with ±0.1 K thermal accuracy.
Is GLP/GMP compliance supported out of the box?
Full compliance requires LabWorldSoft™ with audit trail licensing and user role assignment; hardware-level features (e.g., electronic signature support, secure boot) are embedded.
How is calibration verified and maintained?
Calibration is performed using certified viscosity standards (e.g., Cannon-Manning oils); LabWorldSoft™ logs all verification events with digital signatures and timestamped reports.
Does the system support custom spindle geometries for non-standard samples?
Yes—IKA offers custom spindle design services (e.g., vane, coaxial cylinder, cone-and-plate adapters) upon request, subject to mechanical compatibility assessment.
