Diamond glass knives are widely and important in the laboratory, mainly in the following aspects:
1. Make glassware and experimental setups
Material properties: The blade of the diamond glass knife is made of high-hardness diamond, which has extremely high hardness and wear resistance, and is able to cut the glass surface easily.
Application example: In the laboratory, diamond glass knives are often used to make various glassware and experimental devices, such as test tubes, beakers, reactors, etc. These vessels and devices play an important role in experimental research in chemistry, biology, physics, and other disciplines.
2. Ultra-thin slicing technology
Technology Overview: Ultrathin sectioning technology is one of the most commonly used methods to obtain sample sections, especially in materials science, biology and other fields. Diamond glass knives are a key tool in the ultra-thin sectioning process due to their sharp edge and excellent cutting performance.
Preparation: At room temperature, small pieces of the sample are embedded in epoxy resin, excess resin is removed by trimming, and the sample is cut into thin sections between 50-100 nm thick using a diamond glass knife. The sectioning process involves multiple delicate manual and automated steps that require precise control of sample tilt, rotation, and cutter angle to ensure the quality and integrity of the sectioning.
Automation solutions: With the development of technology, some advanced automation solutions have been applied to the ultra-thin sectioning process, through the built-in camera and image analysis system, the automatic alignment and cutting of the microtome knife and the sample are realized, improving the efficiency and accuracy of the sectioning.
3. Precision machining and microstructure manufacturing
Machining accuracy: The high hardness and sharpness of diamond glass knives enable them to achieve high-precision machining and microstructure manufacturing at the nanometer level.
Applications: In the fields of optics, electronics, semiconductors, etc., diamond glass knives are used to process and manufacture various microstructures and devices, such as optical components, microcircuits, sensors, etc. These microstructures and devices play an important role in scientific research, industrial production, and technological innovation.
4. Other applications
Sample preparation: In the fields of material analysis, biomedicine, etc., diamond glass knives are also used to prepare various samples, such as tissue sections, cell culture dishes, etc., to provide high-quality samples for subsequent experimental research and observation.
Scientific research tools: As an important scientific research tool, diamond glass knife plays an irreplaceable role in promoting scientific research and technological innovation.
In summary, diamond glass knives are widely used in the laboratory, not only for making glassware and experimental devices, but also for ultra-thin sectioning technology, precision machining, and microstructure fabrication. Its excellent cutting performance and wide range of application prospects make diamond glass knives one of the indispensable and important tools in the laboratory.
