RM 200 CP4000 Plus

Save your flow curves and directly calculate your rheological parameters without a computer (including Plastic viscosity, yield stress, Thixotropy, and regression models based on Newton, Bingham, Casson, and Ostwald). Choose your plugin system according to your product constraints.
  • RM 200 CP4000 Plus

The RM 200 CP4000 Plus is a high-performance cone & plate rheometer designed for advanced rheological analysis of paints, coatings, inks, adhesives, cosmetics, and chemical products. Featuring a motorized lift system, automatic measurement range adjustment, and high shear rate capability, it delivers highly accurate and repeatable results even with low-volume samples.

With shear rates of up to 20,000 s⁻¹, the instrument enables detailed evaluation of both Newtonian and non-Newtonian fluids under conditions that closely simulate real application environments. Critical rheological parameters such as yield stress, thixotropy, plastic viscosity, and flow curves can be analyzed directly on the instrument. In addition, regression analysis can be performed according to Newtonian, Bingham, Casson, and Ostwald rheological models.

Temperature control options ranging from -20°C to +300°C, a variety of cone & plate geometries, and multiple measurement systems make the RM 200 CP4000 Plus a comprehensive rheology solution for R&D laboratories, quality control departments, and production facilities. Its low sample volume requirement and computer-independent data analysis capabilities help save time while optimizing testing procedures.

Single Device Multiple Measurement System

Like all Lamy Viscometers, the RM200 CP4000 plus is equipped with multiple measuring systems. With additional measuring spindles, it is possible to perform viscosity measurements and rheological analysis on the same device according to different standards. With RM200 CP4000 plus – Rheometer, it is possible to perform measurements with ISO 3219 (MS-DIN-11-22-33), ISO 2884-1 ICI Cone & Plate, ISO 2555 (apparent viscosity determination by Brookfield method), TS 5809 – Krebs-Stormer and MS-BV1-1000 systems.

Springless Design

Lamy viscometers feature a springless design. This innovative construction is unaffected by ambient temperature changes and eliminates the need for precise leveling using a spirit level. It is suitable not only for high-precision analytical laboratory environments but also for demanding industrial conditions.

Rheological Analysis

With the RM200 CP4000 plus, the rheological behavior of liquids under different shear rates can be analyzed without the need for a computer connection or software. Data can optionally be transferred to a computer using the Rheomatic software.
