We offer the Automatic Polymer Viscometer to our client. The system is also suitable for fully automating viscosity measurements of most other types of polymer solutions dissolved in acids, organic solvents or aqueous solution. This allows for measurement results to form part of legally binding product specifications. The standard price for an instrument includes software coded with the customer's method of choice.
The Polymer Viscometer is available in many different configurations, from fully automated Auto-systems with integrated sample preparation, heating & stirring, to the 1 position RPV-1 Basic entry level viscometer system. At the heart of every RHEOTEK automated viscometer is a glass capillary viscometer tube calibrated in our in-house ISO 17025 accredited calibration laboratory. The capillary measuring principle ensures the highest degree of precision available in the marketplace.
Two automated viscometers allow simultaneous measurements of two samples.
Sample is automatically loaded into the viscometer from auto-sampler rack.
Accurate measurements of flow times to 0.01s using sensors.
Automatic calculation of results.
Automatic cleaning of viscometers and filling stations.

Rheolaser Master is based on optical measurement by MS-DWS. The complexity of polymers and their compounds is a subject to continuous developments. To study these developments this measuring technology is used. Rheolaser was developed for performing passive Microrheology analysis for soft material.
It allows automatic plot of particle Mean Square Displacement (MSD) and microrheological parameters of the material such as elasticity, viscosity and relaxation time
Rheolaser can also analyze the viscoelastic properties of viscoelastic products.
Cosmetic, food, polymer, pharmaceutical, paint and ink industries.
For characterizing viscoelastic fluids, user can plot the viscous and elastic modulus at a chosen frequency (1 Hz for instance) or versus frequencies
This method is also used for analysis of the microstructure like mesh size and relaxation time
Multiple experiments can be performed with the same sample versus time, as it is a non destructive method
Evolution of G’µR, G’’µR, TR µR versus time
Measurement of the perfect gel point by plotting G’’µR /G’µR at several frequencies versus time
Evolution of the polymer mesh size versus time
Evolution of the viscoelastic properties versus the pH, temperature
Structure recovery / thixotropy:
After shearing, automatic plot of G’µR ,G’’µR at rest versus time at a one or several frequencies
Relaxation time TR UR kinetic
The price may vary depending on options and accessories Additional Information:
New concept of viscosity measurement, which mimics the application of high shear like PROTEINS, POLYMERS, PAINTS, INKS, COSMETICS, etc.
The method uses a micro fluidic chip, made of PP or glass and simply flow just few µL or ml test sample along with the reference, the instruments takes the pictures of the flow in the chip and provides direct info on viscosity or stress rheology ( up to 10exp5 /sec) in just few seconds. These chips do not require any calibration and can be cleaned for reuse or disposable.
