CR-3000EX-S

CR-3000EX-S Compact Rheometer – Overview

The CR-3000EX-S is a compact rheometer and physical property testing instrument developed by Sun Scientific, engineered specifically for laboratories and production environments where bench space is at a premium. As the short-type variant in the CR-3000EX series, this material testing instrument delivers the same full-featured performance as the standard CR-3000EX-L model while occupying a significantly smaller footprint. Whether you are evaluating the texture of food products, testing pharmaceutical tablets, or performing quality control on cosmetics and industrial materials, the CR-3000EX-S provides the measurement precision and versatility required for rigorous physical property analysis.

Equipped with 9 distinct measurement modes and an impressive load range from 0.001N to 200N, this compact texture analyzer handles a broad spectrum of testing applications—from delicate gel structures and soft creams to rigid packaging seals and elastomeric components. The instrument's speed range of 0.5 to 1200 mm/min allows operators to simulate real-world conditions with high fidelity, making it an indispensable tool for research and development as well as routine quality assurance workflows.

Despite its reduced vertical clearance, the CR-3000EX-S sacrifices nothing in terms of analytical capability. The short-type design maintains full access to compression, tension, bending, and other standard testing modes, ensuring seamless transition from larger instruments without retraining staff or redesigning test protocols. USB and analog output options facilitate straightforward data acquisition, while automatic clearance adjustment streamlines sample handling and reduces operator fatigue during high-throughput testing sessions.

Ideal for food texture analysis, pharmaceutical hardness testing, cosmetics consistency evaluation, rubber and elastomer characterization, and packaging integrity assessment, the CR-3000EX-S represents the intersection of compact engineering and uncompromised rheological measurement. For quality control managers and R&D scientists seeking a reliable, space-efficient physical property tester, this instrument sets a new standard in benchtop material testing.

Short-Type Rheometer Technology

The defining innovation of the CR-3000EX-S is its short-type architecture, which reconfigures the instrument's mechanical geometry to reduce the overall height without compromising load cell accuracy, drive motor power, or measurement resolution. Traditional rheometers and texture analyzers require substantial vertical clearance, which can limit their deployment in compact labs, mobile testing stations, and inline production environments. The CR-3000EX-S addresses this constraint directly by maintaining the full 0.001–200N force measurement range within a condensed vertical profile.

The instrument supports all essential testing modes for comprehensive material characterization. Compression testing evaluates hardness, firmness, and crush strength—critical for tablet integrity in pharmaceuticals and bite texture in food products. Tension testing measures elongation, breaking force, and adhesive peel strength, essential for packaging seal evaluation and film analysis. Bending and flexural modes assess the rigidity and fracture behavior of brittle materials such as confectionery, snack bars, and thin plastic components.

For production line testing, the compact form factor is a decisive advantage. The reduced height allows the CR-3000EX-S to be installed alongside conveyor systems, within glove boxes, or at workstations with limited overhead clearance. Automatic clearance detection further enhances throughput by eliminating manual probe adjustment between samples. Combined with USB data output for real-time monitoring and analog output for integration with legacy data acquisition systems, the CR-3000EX-S bridges the gap between laboratory-grade measurement and shop-floor practicality.
