Simulating mill refining in laboratory scale
We provide quality control and benchmarking of pulp, offer refining of various types pulps and testing of trial pulp samples. Our LC-refiner also enables production of MFC and serves as a robust platform for testing different refining aids and enzymes.
Our laboratory has a Voith Laboratory refiner with multiple filling options and a PFI mill. Our experts assist in selecting the most suitable refining conditions tailored to your specific pulps.
Wide range of pulp characterization analysis
- Drainability, CSF
- Drainability, SR number
- Water retention value, WRV
- Microscopy fiber characterization
- Fiber length distribution
- Zeta potential
- Shives content
- McNett fractionation
- Sheet preparation
In addition to standard testing methods, we have developed a broad variety of in-house staining and microscopy techniques. Our experts assist with analysis planning and provide detailed interpretation of the measurement results.
