m-VROC II Viscometer — Controlled Shear Rates and Small Samples

m-VROC II is a semi-automated micro capillary Viscometer. Capable of the most demanding applications including small sample protein therapeutics. m-VROC II features the widest dynamic viscosity measurement range with as little as 10 microliters of sample. The m-VROC II allows to get the most out of material samples with the ability to retest and reuse a single sample for multiple measurements. VROC II features a wide shear rate range depending on the chip type up to 2,020,000 s-1 .

Small Samples
Samples as small as 10 μL

Retesting
Retest and retrieve your samples

High Shear
Run shear rate sweeps automatically

Non-Newtonian Samples
Test Newtonian and non-Newtonian fluids

Clariti Data Analysis and post processing

Powerful data analysis software made specifically for VROC powered data. Data analysis can be tedious work. Through Clariti, you can upload all your data into one database, set filters & criteria for data analysis, and generate plots to help illustrate your results. Graphs can be seamlessly rescaled to compare multiple datasets.

Custom Reporting

With Clariti, you can export your analyzed data in multiple file formats, including reports with generated tables and plots. You can interact with Clariti’s smooth user interface to tailor data analysis and aesthetic parameters to your specifications.

Injectability

Clariti is the first software to analyze injectability. After taking any viscosity measurements, you can upload the data and Clariti will calculate the recommended injection rates to help you advance your product developments in injectability.

Intrinsic Viscosity

Clariti allows you to quickly perform intrinsic viscosity analysis, a tool for characterizing size and molecular weight of proteins, particles, polymers, and other systems. As a complementary method to light scattering techniques, Clariti is able to provide quick and accurate measurement analysis.

Complex Aanalysis

Input your data into Clariti and utilize RheoSense AI to conduct complex analyses.
