Product Summary
The Digital Rotational Viscometer is a cornerstone piece of Precision Instrumentation for Quality Control and research in the Polymers & Biomaterials and Materials Chemistry sectors. It provides highly accurate and reproducible measurements of a fluid’s viscosity—a critical parameter for determining material performance, application characteristics, and product consistency.
Unlike simple flow cups, this rotational viscometer utilizes a set of calibrated spindles rotating at precisely controlled speeds to measure dynamic viscosity and is essential for characterizing complex Non-Newtonian fluids like adhesives, paints, coatings, resins, and inks.
Primary Applications
Polymers & Coatings (Adhesives, Paints, Resins):
Quality Control: Rapidly verify the consistency and batch-to-batch uniformity of final products and raw materials.
Application Testing: Determine flow characteristics such as thixotropy (shear thinning) and yield stress, which dictate how a coating will behave during spraying, dipping, or brushing.
Formula Development: Precisely measure the impact of additives, fillers, and temperature on material flow properties.
Materials Chemistry & Suspension Science:
Slurry Characterization: Analyze the stability and flow of high-solids-content slurries used in electrode manufacturing, ceramic forming, and chemical processing.
Rheological Studies: Conduct advanced rheological measurements to understand the fundamental mechanical behavior of semi-solids and complex fluids.
Advantages for Professional Users
Ease of Use: User-friendly digital interface allows for rapid setup and operation, minimizing training time.
Comprehensive Data: Provides more than just a single viscosity number; it offers a detailed rheological profile essential for high-performance formulation.
Temperature Ready: Many models include or are compatible with a dedicated temperature bath/probe, allowing for viscosity measurement under controlled conditions, which is crucial for temperature-sensitive materials.
