Introducing ARO Scientific’s Medical Grade Viscosity Standards

Introducing ARO Scientific’s Medical Grade Viscosity Standards

In regulated industries such as pharmaceuticals, medical devices, and biotechnology, measurement accuracy is critical. Viscosity is a key parameter in many formulations, and results must be both reliable and traceable. To support this requirement, ARO Scientific has introduced a new range of Medical Grade Viscosity Standards, developed for use in controlled and compliance-driven environments.

Why Viscosity Accuracy Matters in Medical Applications

Viscosity directly influences product performance, stability, and process consistency. It is particularly relevant in applications such as:

• Drug formulation and delivery systems
• Injectable solutions and biologics
• Medical lubricants and gels
• Manufacturing quality control

Inaccurate viscosity measurements can lead to variability in product behaviour and may compromise both quality and compliance. For this reason, laboratories rely on certified reference materials (CRMs) to verify instrument performance and ensure data remains defensible. A broader overview of available materials can be found within ARO’s viscosity standards range.

Traceability and the Role of Reference Standards

The use of viscosity standards is supported by established international methodologies and analytical best practice. ASTM D2162 defines the calibration of master viscometers and the production of viscosity reference materials, providing traceability.

In addition, certified reference materials are widely used to ensure measurement accuracy, with defined uncertainty and traceability forming a core part of laboratory quality systems. These principles align with the requirements of ISO/IEC 17025 and ISO 17034, which govern laboratory competence and the production of reference materials.

New Medical Grade Standards

ARO Scientific’s Medical Grade Viscosity Standards have been developed in line with these recognised requirements.

Key features include:

• Certification to ISO/IEC 17025 and ISO 17034
• Full traceability to international standards
• Characterisation using ASTM D2162 and ASTM D1480 methodology
• Production within Aro Scientific’s UKAS-accredited calibration laboratory

This combination ensures the standards are suitable for calibration, validation, and verification activities in regulated laboratories.

Available Medical Grade Viscosity Standards

The ARO Scientific Medical Grade Viscosity Standards range covers low-viscosity fluids typically required for pharmaceutical and medical applications. Each material is supplied as a certified reference material with defined viscosity values at controlled temperatures, commonly 25 °C and 37 °C, to support both ambient and physiological testing conditions.

A summary of the available products is provided below:

Nominal values are indicative and may vary slightly depending on batch certification. Users should refer to our certified values data table or individual certificate of analysis for certified values and associated uncertainty.

These standards are formulated for stability and consistency and may include antibacterial agents to minimise degradation during storage and use. Each product is supplied with certification in accordance with ISO/IEC 17025 and ISO 17034, ensuring traceability and defined measurement uncertainty.

Designed for Laboratory Use

The range has been developed with routine laboratory use in mind:

• A broad viscosity range to support different applications
• Availability in multiple pack sizes
• Tamper-evident glass packaging
• Formulation designed for stability
• A defined shelf life to support inventory control

The focus is on providing materials that are technically robust while remaining straightforward to implement within existing workflows.

Supporting Compliance and Method Validation

Regulatory expectations require clear evidence of instrument performance and method suitability. In practice, viscometers and rheometers must be calibrated using fluids with known and stable viscosity values.

The use of certified, traceable materials helps ensure consistency of results and supports audit readiness, particularly in pharmaceutical and medical device environments.

Manufactured in the UK

The standards are manufactured in the United Kingdom under controlled conditions, with certification recognised through international accreditation frameworks. This supports their use across laboratories operating within global quality systems.

Conclusion

ARO Scientific’s Medical Grade Viscosity Standards provide a reliable solution for laboratories requiring traceable, certified materials for viscosity measurement. Developed in line with established methodologies and supported by recognised accreditation, they offer a practical approach to maintaining measurement confidence in regulated environments.
