Reusable One-Part, Solid Shaft Spindle, SC4-21

Reusable One-Part, Solid Shaft Spindle, SC4-21

Reusable SC4 Spindles and Measuring Chambers are precision-engineered components designed for use with Rotational Viscometers, making them essential tools for asphalt binder testing in compliance with ASTM D4402 and AASHTO T 316 standards. These spindles and measuring chambers offer exceptional accuracy and versatility, ensuring reliable viscosity measurements across a wide range of asphalt binder characteristics.

Each SC4 spindle is constructed from durable 316 stainless steel and features a magnetic coupling for seamless operation. With a variety of size and shape options available, the spindles are capable of distinguishing viscosities and asphalt binder properties ranging from standard to modified binders. Rotational Viscometers equipped with Toolmaster™ technology automatically recognize Anton Paar spindles, eliminating the risk of spindle selection errors and providing fully traceable, repeatable results.

Spindle Shaft Options

Multiple spindle shaft options are available to meet diverse testing requirements:

• Hook-Type Shaft Spindles: Ideal for modified binders with medium-to-high temperatures and low viscosity. These are the most popular choice for such applications due to their ease of use and reliability.
• Solid Shaft Spindles: Available in one-part or two-part designs, these spindles are better suited for testing unmodified binders with higher viscosity, offering robust performance under demanding conditions.
• Disposable Spindles: Perfect for applications where contamination risk must be minimized or when cleaning reusable spindles is impractical.

Measuring Chambers

The Reusable Stainless Steel Measuring Chamber complements all reusable spindle types, providing a durable solution for repeated testing. Designed for compatibility, it ensures long-term reliability and precision. For laboratories seeking convenient, single-use options, a Disposable Spindle and Measuring Chamber is also available, reducing cleaning time and potential cross-contamination.

Key Features

• Automatic Spindle Recognition: Toolmaster™ technology ensures correct spindle identification, reducing errors and standardizing results.
• High-Quality Stainless Steel Construction: Resistant to wear and corrosion for long-lasting durability.
• Versatile Design: Accommodates a wide range of viscosities and asphalt binder characteristics.
• Reusable and Disposable Options: Choose the best solution for your testing needs, balancing durability and convenience.

Applications

These spindles and measuring chambers are indispensable for asphalt binder testing in research labs, quality control environments, and material testing facilities. Whether you're testing modified binders at elevated temperatures or unmodified binders with higher viscosities, the SC4 system delivers accurate, consistent results to meet industry standards.
