In scientific research and experiments, the handling of samples is a critical step in conducting various experiments and analyses. As an advanced sample processing equipment, the automatic liquid nitrogen freezing grinding machine has the characteristics of high efficiency, non-destructive, fast and accurate, and is widely used in various fields, such as geology, biomedicine, material science, etc. This article will introduce in detail the working principle, characteristics, advantages and application scenarios of the automatic liquid nitrogen refrigeration grinder, and its importance and value for achieving non-destructive sample processing.
1. The working principle of automatic liquid nitrogen freezing grinder.
The automatic liquid nitrogen refrigeration grinder mainly completes the sample processing through the following steps:
Liquid nitrogen freezing: Samples to be processed are quickly thrown into liquid nitrogen to allow them to be frozen quickly. Liquid nitrogen is an ultra-low temperature refrigerant that can reach temperatures up to -196 and can quickly freeze samples into a solid state.
Grinding: The frozen sample is placed in the grinding chamber and the sample is broken and ground by means of grinding beads. During the grinding process, the sample is continuously recycled until the desired fineness is reached.
Separation and screening: The ground sample is separated and screened to separate the broken particles from the unbroken sample to obtain a finer sample.
Repeat the above steps: For some samples that require further processing, the above steps can be repeated to achieve better processing results.
2. Features and advantages of automatic liquid nitrogen freezing grinder.
The automatic liquid nitrogen refrigeration grinder has the following features and advantages:
High efficiency: The automatic liquid nitrogen freezing grinder can quickly process a large number of samples, which can realize automatic batch processing and improve work efficiency.
Non-destructive: The automatic liquid nitrogen freezing grinder will not introduce additional substances or change the chemical properties of the sample when processing the sample, ensuring the non-destructiveness and authenticity of the sample. This is one of the biggest advantages of the device, especially in the fields of biomedicine and materials science.
Rapidity: Liquid nitrogen freezing technology can quickly freeze the sample into a solid state, avoiding the influence of temperature changes during the processing process and reducing the processing time.
Accuracy: The automatic liquid nitrogen freezing grinder adopts advanced control systems and sensors, which can accurately control the grinding time and grinding strength to ensure the accuracy and consistency of sample processing.
Reproducibility: The automatic liquid nitrogen refrigeration grinder adopts a standardized operation process, which can ensure the repeatability and comparability of the processing results, which is conducive to the reliability of experimental results.
