1、 Introduction to DK-2010A Headspace Sampler:

The DK-2010A semi-automatic headspace sampler is a new generation upgraded product of our company's semi-automatic headspace sampler. The sample bottle constant temperature furnace station of this instrument is designed with a circular distribution, which is more reasonable and minimizes the temperature gradient of all headspace bottle heating positions, improving the stability and reliability of analysis results. The injection needle can be freely replaced, making it convenient to connect various models of gas chromatographs at home and abroad.
