Overview
The circular electric water bath Nitrogen blowing instrument adopts purge and trap technology, combined with temperature control heating, and uses nitrogen and other inert gases to quickly, controllably and continuously purge the surface of the sample to achieve oxygen-free condensation of the sample solution. This method has the characteristics of time saving, convenience and accuracy, and is widely used in food safety, pesticide residue detection, clinical drug substitution and other fields.
Features
1. The LED digital tube displays the set temperature and the current temperature, which is clear and intuitive.
2. Adopt PID temperature control technology and realize over-temperature alarm.
3. The parts that may come into contact with the solvent are made of 316 stainless steel, which has a long service life and is easy to clean.
4. Unique self-equilibrating suspension remote control motor lifting system makes the height adjustment of the distribution room more flexible.
5. Independent valves and independent blowpipes make the nitrogen blowing target clearer, saving nitrogen and making it less prone to cross-contamination.
6. The purging device can be 360 ° swirl/spin, and the height of each blowing needle can be adjusted individually, which is convenient for taking and placing individual samples.
7. Water Bath Heating mode, heating more evenly.
Principle
The instrument conducts temperature-controlled heating of the sample through a water bath, and uses inert gases such as nitrogen to quickly, controllably and continuously purge to the surface of the sample solution. Gas purging accelerates solvent volatilization and realizes rapid condensation of the sample in an oxygen-free environment.
Applications
Food safety, pesticide residue detection, clinical drug substitution
