Nitrogen blowing instrument usually blows nitrogen to the heated sample surface to concentrate the sample, which has the characteristics of time saving, convenient operation and easy control, and can get the expected results quickly. Widely used in pesticide residue analysis, commodity inspection, food, environment, pharmacy, biological products and other industries, as well as sample preparation for liquid phase, gas phase and mass spectrometry analysis. It has played a practical role in the fields of pharmacy, food safety, especially infant dairy products, medical examination and pesticide residues, providing a time-saving and efficient platform for sample preparation and treatment in gas chromatography (GC), liquid chromatography (HPLC) and other analytical means, and is the best supporting equipment for solid phase extraction technology.
Beijing Zhongxin Jiayi Technology Co., Ltd. is a technical company specializing in laboratory research and development, production, sales and service. ZX-DCG nitrogen blower can be used for centrifugal tubes, test tubes, conical bottles and other containers, and the electric lifting system is convenient for observing the sample purging situation and taking and placing samples more conveniently. The height of each blowpipe can be adjusted independently, which is beneficial to the experiments of different batches and samples.
