Reasons for using a high-throughput tissue grinder

Sample pretreatment is a time-consuming and very easy error-producing step in the process of experimental analysis. The effect of sample processing will directly affect the final result of subsequent analysis. Therefore, in order to improve the efficiency of analysis and measurement, the accuracy and representative of the measurement results are improved. Sex, in the sample grinding process must rely on professional equipment such as high-throughput tissue grinder.
Because the food sample belongs to the composite matrix system and contains many components such as protein, oil, carbohydrate, pigment, etc., the complex matrix background will cause great troubles for the extraction, separation, purification and determination of the target compound to be analyzed, so the food is Sample preparation is not only complicated but also decisive for the accuracy, reliability and sensitivity of the results. The use of specialized instruments such as high-throughput tissue grinders can greatly increase the efficiency of the experiment. The instrument can pulverize, mix, homogenize and break the sample by twisting and swaying inside the sample tube through tungsten carbide beads or stainless steel beads, and can rapidly pulverize and homogenize the samples such as hard, soft and elastic. In accordance with the requirements of physical and chemical analysis laboratories, grinding tanks of different volumes and materials can be used for dry grinding, wet grinding and freeze grinding, suitable for DNA/RNA extraction experiments.
A large number of practices have proved that the method of grinding corn leaves with high-flux tissue grinder can be used to freeze the grinding of corn leaves. The grinding tube and adapter can be directly immersed in liquid nitrogen, only one-time 1-2 minutes of liquid nitrogen freezing and one time. With 2 minutes of grinding, up to 54 2.0 ml samples can be comminuted in batches. The treatment time is fast, effectively preventing the temperature rise, and providing a guarantee for the subsequent effective advancement of nucleic acid. In addition, it also saves a lot of liquid nitrogen and is safer to operate.
