Dry Nitrogen Blowdown Instrument

The dry nitrogen blowdown instrument heats the sample tube via a heating block while blowing nitrogen over the liquid surface to accelerate solvent evaporation. It is used for concentrating or drying samples during pretreatment and is suitable for applications such as environmental testing and food safety analysis.
Selection
When selecting, consider matching the sample capacity with the number of heating holes, ensuring the heating temperature range covers the boiling points of commonly used solvents. Adjustable nitrogen flow should be available to ensure gentle concentration. The material should be corrosion-resistant, and the operation interface should be intuitive for easy control of the concentration process.
