Description

Technical Field

[0002] Vortex mixers are commonly used testing equipment by various testing and inspection institutions, colleges and universities, research institutes and individuals in the process of conducting testing, scientific research and teaching training. They are especially frequently used in the testing and research of pesticide and veterinary drug residues and additives in food.
