General Information


Rheometric Mechanical Spectrometer (RMS 800)


Polymer Materials and Engineering, room 0.040, Faculty of Applied Sciences, Julianalaan 136, 2628 BL Delft

Key words:

viscosity, visco elastic liquids, dynamic shear, steady shear, Rheology

Main application:

The instrument is intended to be used as a mechanical test system for evaluating viscoelastic properties of materials.
The materials may be in solid, melt or liquid state. The instrument may be operated in either dynamic or steady mode.

Dynamic mode: Elastic modulus G', viscous modulus G'', loss tangent (tanδ) and derived quantities.

In this mode the instrument applies a precise sinusoidal shearing to the sample and precisely measures the samples response.

Steady mode: The instrument subjects the test sample to a rotational shear shear at a given shear rate and measures the resulting shear stresses τ and steady shear viscosity η .

Instrument specification

Dynamic mode:
10-2 rad/s < ω < 1000 rad/s (sinusoidal)

10-2 rad/s < ω < 1000 rad/s (sinusoidal)

Sensitivity: 2000 grams

Temperature range: from room temperature up to 500 celsius

Sample size: 2-3 grams

Software: Orchestrator
