1.indistinct blood vessels

（1）The veins in patients with edema are often not obvious. It is better to press the local area with the finger according to the position of the vein flow to temporarily dissipate the subcutaneous water, and then puncture the vein after exposing the vein.

（2）In obese patients, the vein is deep and not obvious, but it is relatively fixed and does not slide. After finding the position of the blood vessel, the needle is deeply inserted at an oblique angle of 30°. After the blood is returned, the needle is slightly lifted and sent into the blood vessel.

The blood vessels of patients with chronic wasting disease are relatively fragile, and the needle should be inserted from the side of the blood vessel. When piercing, the direction of the needle should be parallel to the blood vessel, and the needle should not be too forceful when entering the blood vessel.

The correct selection of quartz crucible can not only ensure the best performance under high temperature applications, but also effectively avoid potential safety hazards. This paper discusses the key factors to be considered in selecting quartz crucible, and provides practical guidance for researchers and production personnel.

The Importance of Quartz Crucible Size and Shape Matching

The size and shape of the quartz crucible is the primary consideration in the selection process. Different processes have strict requirements on the size of the crucible to adapt to the processing needs of different volumes of materials. Too small size of the crucible may lead to melting material overflow, not only cause material waste, but also may lead to safety accidents; The large size of the crucible may be too large due to the surface area, resulting in low heating efficiency and increased energy consumption. Therefore, when selecting quartz crucible, it is necessary to accurately match the size and shape of the crucible according to the specific application needs, to ensure that the molten material can be fully placed in the crucible, while achieving efficient heating.

Evaluating Thermal Conductivity for Quartz Crucible Heating Uniformity

The thermal conductivity of quartz crucible is the key factor to determine the heating uniformity. Quartz crucibles with high thermal conductivity can quickly transfer heat and achieve uniform heat distribution, which is essential for processes that require precise temperature control. Uneven heating will result in a large temperature gradient inside the molten material, which will affect the microstructure and final properties of the material. Therefore, when selecting quartz crucible, it is necessary to evaluate its thermal conductivity to ensure that the selected crucible can meet the requirements of temperature uniformity of the process, so as to obtain high-quality products.

Understanding Application Requirements for Quartz Crucible Performance

In addition to size and shape, thermal conductivity, the selection of quartz crucible should also consider its application needs. Different processes have different requirements on the performance of the crucible, and some require the crucible to have excellent chemical stability to resist the erosion of molten materials; Some require the crucible to have strong thermal shock resistance to cope with sharp temperature changes. Therefore, when selecting a quartz crucible, it is necessary to deeply understand the performance requirements of the specific application and select a crucible with corresponding performance advantages to ensure that the crucible can maintain stability in a harsh working environment without sacrificing performance.

In summary, the selection of quartz crucible needs to consider the size and shape, thermal conductivity and application requirements and other key factors. By precisely matching the application requirements and selecting quartz crucible with excellent performance, not only can ensure the best performance under high temperature applications, but also effectively avoid potential safety hazards. In the future, with the continuous development of science and technology, the performance requirements of quartz crucible will be higher and higher, researchers and production personnel need to continue to pay attention to the development of new technologies and new materials, and constantly optimize the selection strategy of quartz crucible to meet the growing application needs.

However, compared to quartz, alumina crucibles are slightly less resistant to thermal shock, which limits their use in processes involving rapid temperature changes. In addition, alumina can introduce impurities at high temperatures, which can be a major drawback for applications where purity is very high.

Zirconia Crucible: Benefits and Challenges in High-Temp Applications

Zirconia crucible, with its extremely high melting point and excellent durability, is ideal for extreme high temperature conditions. Its excellent high temperature resistance ensures long-term reliability of the material in high temperature environments. However, zirconia crucibles typically cost more than quartz crucibles and, in some analytical applications, are less transparent than quartz, which limits their applicability in applications where internal reaction processes need to be observed. In addition, zirconia may react with certain materials, resulting in contamination problems, which require special attention when used.

Graphite Crucible: Application Scope and Limitations

Because of its high thermal conductivity and ability to withstand extreme temperatures, graphite crucible has been widely used in specific fields such as metal melting. Its high thermal conductivity helps to heat the material quickly and evenly, improving the melting efficiency. However, the interaction between graphite and molten metal can lead to contamination problems, which is unacceptable in sensitive applications. Therefore, although graphite performs well in some specific scenarios, for applications requiring a high purity and inert environment, quartz crucible is more popular due to its purer and inert properties, becoming the first choice of many researchers and manufacturers.

In summary, quartz crucible, alumina crucible, zirconia crucible and graphite crucible each have their own unique performance advantages and application scenarios. When selecting crucible materials, factors such as process requirements, cost effectiveness, material purity and potential contamination risk should be considered comprehensively. Because of its excellent thermal shock resistance, high purity and inertness, quartz crucible performs well in environments requiring high purity and sensitive applications, making it the material of choice in many fields. However, for specific application scenarios, such as extreme high temperature conditions or cost-sensitive projects, other crucible materials may also be a suitable choice. Therefore, in practical applications, the most suitable crucible material should be selected according to the specific needs of the trade-offs.
