Overview
The ATAGO VISCO Series Temperature-Controlled Rotational Viscometer is an engineered solution for precise, repeatable viscosity measurement of Newtonian and non-Newtonian fluids under regulated thermal conditions. Based on the principle of rotational viscometry—where torque required to rotate a spindle at a defined angular velocity within a sample is measured—the instrument delivers quantitative rheological data reflective of internal molecular friction. Designed specifically for personal care formulations (e.g., shampoos, conditioners, toothpastes, lotions), this system integrates active Peltier-based temperature control to eliminate thermal drift and ensure measurement stability across extended testing cycles. Its compact, portable architecture supports both benchtop laboratory use and field deployment, making it suitable for QC labs, R&D pilot lines, and supplier audits where environmental flexibility and regulatory traceability are essential.
Key Features
- Integrated Peltier temperature control unit enabling precise sample conditioning from 5.0 °C to 90.0 °C with ±0.2 °C accuracy and 0.1 °C resolution
- Low sample volume requirement (as little as 15 mL), compatible with disposable paper cups—eliminating cross-contamination and reducing cleaning overhead
- Dual power operation: AC adapter for continuous lab use and standard alkaline batteries for mobile or off-grid applications
- Backlit LCD display showing real-time viscosity (mPa·s), % torque, spindle identifier, and maximum measurable viscosity at current speed
- USB interface compliant with CDC (Communication Device Class) protocol for direct data streaming to Windows-based PCs without proprietary drivers
- Pre-calibrated spindles (LV, RV, HA, HB series) with NIST-traceable calibration certificates available upon request
Sample Compatibility & Compliance
The VISCO platform accommodates a broad spectrum of semi-solid and viscous liquids typical in personal care manufacturing—including surfactant-rich systems, polymer-thickened gels, emulsions, and suspension-based actives. Its design conforms to ASTM D2196 (Standard Test Methods for Rheological Properties of Non-Newtonian Materials Using a Rotational Viscometer) and supports alignment with ISO 2555 and USP for viscosity assessment of pharmaceutical and cosmetic preparations. The temperature-controlled module satisfies GLP documentation requirements when paired with optional audit trail logging software, and its hardware architecture permits integration into GMP environments requiring 21 CFR Part 11-compliant electronic records (via third-party validated data acquisition platforms).
Software & Data Management
While the VISCO operates autonomously via front-panel controls, its USB interface enables seamless export of time-stamped viscosity readings, temperature logs, spindle ID, and rotational speed to CSV or Excel-compatible formats. When used with ATAGO’s optional VISCO-Link software (Windows 10/11), users gain access to automated method templates, statistical process control (SPC) charting, batch comparison overlays, and configurable pass/fail limits aligned with internal specifications. All exported datasets retain embedded metadata—including operator ID, timestamp, ambient temperature, and calibration status—for full traceability in quality review workflows.
Applications
- Personal Care & Cosmetics: Viscosity profiling of shampoos, conditioners, facial cleansers, sunscreens, and hydrogel masks during formulation development and batch release
- Pharmaceuticals: Consistency verification of topical gels, oral suspensions, and ophthalmic solutions per compendial monographs
- Food & Beverage: Monitoring texture stability of yogurts, sauces, dressings, and confectionery fillings across shelf-life studies
- Chemical Manufacturing: Quality control of thickeners, dispersants, and rheology modifiers in industrial surfactant blends
- Academic Research: Teaching core viscometric principles and conducting comparative flow behavior analysis in undergraduate and graduate laboratories
FAQ
What spindle configurations are supported by the VISCO Temperature-Controlled model?
Standard LV, RV, HA, and HB spindles are compatible; each is supplied with individual calibration constants traceable to JIS Z 8803 and ISO 17025-accredited reference standards.
Can the instrument perform yield stress estimation?
No—this is a steady-shear rotational viscometer optimized for apparent viscosity determination at discrete shear rates; yield stress quantification requires controlled-stress or oscillatory rheometry.
Is the temperature chamber compatible with aggressive solvents such as ethanol or acetone?
The sample cup holder and thermal block are constructed from chemically resistant anodized aluminum and stainless steel; however, direct immersion of non-aqueous solvents into the temperature bath is not recommended—use only approved disposable cups or glass containers rated for thermal cycling.
How frequently does the system require recalibration?
Annual recalibration is recommended for ISO/IEC 17025 compliance; interim verification using certified silicone oil standards (e.g., Cannon-Fenske or Brookfield N-series) is advised before critical measurements.
Does the device support automatic multi-speed viscosity profiling?
Yes—up to 10 pre-programmed speed steps can be sequenced via the front panel or external software, enabling quick construction of flow curves for pseudoplastic or dilatant materials.
