Automated viscometer for small samples: m-VROC II
- Accurate, fast & high-precision viscosity testing
- Samples as small as 10 µL
- Wide Viscosity Range: 0.4 ~ 100,000 mPa-s (or cP)
- Runs temperature and shear rate sweeps
- Easy to use with integrated automatic cleaning
The m-VROC II is the next generation leading small sample microfluidic viscometer. Capable of the most demanding applications including small sample protein therapeutics, m-VROC II features the widest dynamic range viscosity measurement with as little as 10 microliters of sample. The m-VROC II allows you to get the most out of your samples with the ability to retest and reuse a single sample for multiple measurements.
Key Features & Benefits:
Ultra-Fast & Accurate
Patented VROC® (Viscometer-Rheometer-on-a-Chip) technology ensures high-precision results even for complex fluids like polymers, emulsions, and suspensions in seconds with minimal sample preparation.
The closed system of “sample-syringe-measuring cell” prevents any evaporation or contamination and ideal to perform the stability studies over time.

Small Sample Volume Requirements
The m-VROC II requires only 10 µL, making it ideal for expensive or limited-quantity samples (e.g., biologics, pharmaceuticals). Reduces waste and cost.
The integrated “retest and retrieve” function gives the possibility to perform the temperature and shear rate sweeps on the same sample.
The integrate cleaning station perform cleaning of all parts which were in contact with a sample automatically after each test.

User-Friendly Software
Intuitive interface with real-time data tracking & graphing, export, analysis, and compliance with 21 CFR part 11 requirements.
The powerful add-on software Clariti™ utilizes AI and enables conducting complex analyses for infectability, intrinsic viscosity, hydrodynamic radius and much more.
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.

Wide Shear Rate Range for Maximum Flexibility
m-VROC II uses a pressure-sensor-based method to directly measure viscosity without requiring shear rate calibration. With an impressive shear rate range of 0.86 to 2,020,000 s⁻¹, the instrument enables precise characterization of a wide variety of samples and suitable for both low (creep flow) and high (injection molding) shear applications.
Precise Temperature Control
Integrated Peltier control unit for precise temperature regulation (4°C to 70°C) ensures consistent, repeatable data. The system gives the flexibility to the user to control the temperature independently in the sample holder and the test syringe / measuring cell. The m-VROC II achieves rapid thermal equilibrium due to small sample size (1–2 minutes).
Robust Design
Compact, durable design ideal for lab, QC, and production environments. No moving parts in contact with the sample, reducing maintenance and avoiding errors from rotor inertia.
Industry Compliance
Meets ASTM, ISO, USP and other global standards for viscosity and rheological testing. VROC software is 21 CFR part 11 compliant, providing multi-level user access to ensure data integrity & prevent potential data manipulation.
