Isolation and Valorisation Tools

Besides the standard equipment present in every chemical laboratory and the analytical instrumentation, we commonly use the following extras to access and valorize natural polyphenols:


Picture
Flow-chemistry set-ups
... for fast, efficient and scalable purification, fractionation and
    modification of natural polyphenols.


Ultrasonicator
... for ultrasound-mediated disintegration of natural materials
    and  
    the chemical transformations and generation of polyphenol
    aggregates.

Wiley mill
... for grinding wood and bark to 1-5 mm sized particles for further
    ball-milling or Sohlet-extractions.


Ball mill
... for further grinding any natural materials to fine powders.

Parr reactor
... for our home-made pulping runs.

Freeze-dryer and vacuum oven
... for drying the isolated and chemically modified lignins and
    tannins as gentle and as fast as possible.
