With the continuous development of science and technology, the semiconductor industry has higher and higher requirements for the storage and transportation of chemicals in the production process. In this context, PFA volumetric flasks have gradually become the preferred container in the industry due to their unique properties and advantages. PFA volumetric flasks, also known as soluble PTFE volumetric flasks and Teflon volumetric flasks, are commonly used in 10ml, 25ml, 50ml, 100ml, 250ml, 500ml, 1000ml and other specifications.
The Teflon PFA volumetric flask is a clear, long-necked flask with a pear-shaped body for easy liquid shaking and brushing. The graduation marks on each PFA volumetric flask are weighed and marked with a thousandth of an electronic balance.
It is widely used in ICP-MS, ICP-OES and other trace analysis and isotope analysis experiments, including environmental monitoring, and is suitable for semiconductor, polysilicon, photovoltaic electronics, and lithium battery industries. In all kinds of testing laboratories, the quality performance is good, which will not affect the purity of the test samples.
In the semiconductor industry, PFA volumetric flasks are mainly used to transport various chemicals and configure solvents, such as photoresists, etching solutions, cleaning solutions, etchings, etchings, etchings. These chemicals play a vital role in the production process, and PFA volumetric flasks are able to ensure their safety and stability during storage and transportation. By using PFA volumetric flasks, companies can reduce chemical exposure to air and water, reduce the risk of contamination, and improve production efficiency. In addition to storing and transporting chemicals, PFA volumetric flasks have many other applications in the semiconductor industry. For example, in the production process, large quantities of high-purity gases are used. PFA volumetric flasks can be used as an alternative to gas cylinders for transporting these high-purity gases. Due to the excellent corrosion resistance and air tightness of the PFA volumetric flask, it is possible to ensure that the quality and purity of the gas are not compromised.
What are the specific characteristics of them? Let's take a look.
1.Good transparency, stability, the naked eye can see the smooth surface of the bottle volume, the inner and outer walls of the bottle are smooth, easy to clean, do not adhere to the sample, and the inner wall of the bottle mouth is not easy to have liquid residue;
2.The bottle mouth and cap are well sealed, and the matching screw cap is tight, so that the liquid will not leak when inverted or placed on the side;
3.Resistant to strong acids, strong alkalis, aqua regia, various strong corrosive acids commonly used in laboratories and various organic solvents;
4.Low background and low precipitation: no dissolution and precipitation, low background can reach the low detection limit of ICPMS, and it is a vessel for storing reference materials, strong corrosiveness, and expensive ultra-high purity reagents;
5.High and low temperature resistance: operating temperature -200 +260;
6.Anti-pollution: The value of metal elements is low, and the content of metal elements such as lead and uranium is less than 001ppb；
