Laboratory Nitrogen Blowdown Instrument

The laboratory nitrogen blowdown instrument accelerates solvent evaporation and achieves sample concentration by heating the sample and introducing nitrogen gas. It is used for sample pre-treatment in fields such as environmental testing and food safety analysis, serving as an alternative to rotary evaporators for rapid concentration of small volumes.
Selection
When selecting, consider matching the sample characteristics with the heating method: water bath heating is suitable for heat-resistant samples, while dry heating is appropriate for high-temperature requirements. Choose the number of wells based on the sample volume, and pay attention to the precision of nitrogen flow adjustment and the design for preventing cross-contamination. Ensure compatibility with commonly used test tube specifications.
