easyRheo Pico makes it possible to take reliable measurements on very small sample volumes, which is especially relevant for high-value products or those available in limited quantities, such as injectable pharmaceutical solutions.
In one customer case, using the easyRheo Pico reduced the sample volume consumed per measurement by a factor of 6. This significant drop in consumption represents a saving of several tens of thousands of euros in products consumed per year.

Frequently Asked Questions about easyRheo Pico
What viscosity range can easyRheo Pico analyze?
With the right geometries, easyRheo Pico can measure sample viscosity from several hundred Pa.s down to very low viscosities, such as that of air at 1.8 x 10-5 Pa.s
What products are relevant to analyze with easyRheo Pico?
Any sample can be analyzed as long as it falls within the right viscosity range. However, easyRheo Pico is especially relevant for analyzing specialty inks and coatings, very-low-viscosity biofluids (blood, synovial fluid, tears, etc.), vaccines and biologics, foams, and sprays.
What is the difference between easyRheo and easyRheo Pico?
The main difference between easyRheo and easyRheo Pico lies in the range measurable by their sensors, with easyRheo Pico dedicated to measuring low rheological properties. The software and geometries are identical
What is the minimum volume needed to perform an analysis?
The minimum volume required to take a measurement on easyRheo Pico is 20 µl.
Is easyRheo Pico difficult to learn to use?
easyRheo Pico keeps the easyRheo DNA. The software interface is guided and walks you through every step (protocol selection, sample preparation, launching the measurement, and interpretation) with explanatory text and tutorial videos built directly into the software, no external documentation needed.
Its preprogrammed protocols and automatic curve analysis (thresholds, rheological models, moduli) deliver usable results with no manual post-processing. Most users become self-sufficient in under 30 minutes, whether they are QC technicians, formulators, or production operators.
Does easyRheo Pico require compressed air or any additional equipment?
No. Thanks to its patented magnetic bearings, easyRheo operates without compressed air, and its air cooling removes the need for an external thermostatic bath. Its compact size lets it be installed without constraints on a standard benchtop, a real advantage for production lines and laboratories where space is limited.
