1 Product Introduction PFA volumetric flasks, also known as soluble polytetrafluoroethylene volumetric flasks or Teflon volumetric flasks, are available in two new options: threaded and plug-in. Currently, there are specifications of 10ml, 25ml, 50ml, 100ml, 250ml, 500ml, and 1000ml available, ensuring product quality. The Teflon series PFA volumetric flask is a transparent long neck bottle with a pear shaped body, making it easy to shake liquids and scrub. The scale lines on each PFA volumetric flask are measured and labeled using an electronic balance of one thousandth. Widely used in trace analysis and isotope analysis experiments such as ICP-MS, ICP-OES, environmental monitoring, semiconductor, polysilicon, photovoltaic electronics, and lithium battery industries. In various testing laboratories, good quality performance will not affect the purity of the test samples. 2 Product performance 1. Good transparency, stability, visible to the naked eye with a smooth surface of the bottle volume, smooth inner and outer walls of the bottle, easy to clean, non adhesive to the sample, and no liquid residue on the inner wall of the bottle mouth; 2. The bottle mouth and cap are well sealed, and the matching threaded cap is tight, so there will be no leakage of liquid when placed upside down or on the side; 3. Resistant to strong acids, alkalis, aqua regia, various laboratory commonly used strong corrosive acids, and various organic solvents; 4. Low background and low precipitation: There is no dissolution or precipitation, and the low background can reach the low detection limit of ICP-MS. It is a container for storing standard materials, strong corrosiveness, and expensive ultra-high purity reagents; 5. High and low temperature resistance: operating at temperatures ranging from -200 to+260 ; 6. Pollution prevention: The value of metal elements is low, and the content of metal elements such as lead and uranium is less than 0.01PPb;
