Centrifugal Concentration
Centrifugal vacuum concentrators use a combination of centrifugal force, vacuum, and heat to rapidly and gently evaporate multiple small samples to either a dry or a wet pellet state.
There are many different applications for centrifugal evaporation, including concentration of polynucleotides and protein samples, residue analysis, concentration of solvent/water mixtures, toxicology and forensics, combinatorial chemistry, and food/environment analytics. Because of the nature of the solvents used, a pump with high chemical resistance and good tolerance of condensates is recommended.
Considerations for selecting the optimal pump include:
- Sensitive vacuum control
- Oil-free operation with excellent chemical compatibility
- Ability to process wet vapours

Products for Centrifugal Concentration
Degassing & Desiccation
Degassing separates dissolved gases from liquids, which is critical in applications where gases can affect the final result. Desiccation, however, removes moisture from solids or maintains a dry environment for moisture-sensitive materials. Both processes require a vacuum desiccator and a pump to generate the required vacuum.
