Overview

Use an inclined nitrogen blowing needle to blow air into the sample tube in the water bath to form a vortex air flow, which ultimately makes the sample vortex and oscillate to increase the concentration speed. At the same time, the solvent continuously purges the sample tube wall to reduce analyte residues on the sample tube wall and improve the recovery rate.
The nitrogen blowing needle does not extend into the sample tube and does not touch the sample. It requires no cleaning of the nitrogen blowing needle and reduces cross-contamination. The vortex airflow prevents the sample from flying around. No condensation reflux phenomenon.

Features:

• Parallelism: Temperature error of each sample position: 1℃; gas flow error of each nitrogen blower: ±5%.
• Sample position control: Each row of samples is independently controlled.
• Other functions: Side visual window; Built-in air extraction system; Real-time change method; High and low pressure alarm;Low water level alarm.
