1. Teflon digestion tube semi-transparent milky white transparent color complete
Teflon digestion tube is mainly used in food, disease control, Academy of Agricultural Sciences, medicine, agriculture, forestry, environmental protection, chemical industry, biochemical and other industries, as well as colleges and universities, scientific research departments on soil, blood samples, urine samples, nails, food, dairy products, agricultural and sideline products, feed, heavy metals, ores and other chemical analysis of the sample digestion treatment, can be used with atomic absorption, atomic fluorescence and heavy metal electrothermal digestion instrument and other analytical instruments.
Teflon (PTFE) digestion tube has good resistance to commonly used chemical drugs, the opening can be autoclaved, the inner wall is smooth, flat bottom, round bottom, pointed bottom products can be customized, the bottle mouth can also be processed into a socket or threaded mouth, and can be matched with 12-bit, 36-bit, 54-bit digestion instruments to do digestion experiments together.
PTFE Chinese name is also called "Teflon" (teflon), "Teflon", "Teflon", "Teflon" and so on. it is a polymer compound formed by polymerization of tetrafluoroethylene, and its structural formula is-[-CF2-CF2-]n-. it has excellent chemical stability and corrosion resistance, and is one of the materials with good corrosion resistance in the world today. besides molten alkali metal, lv trifluoride, green pentafluoride and liquid fluorine, it can withstand all other chemicals and will not change when boiled in aqua regia, it is widely used in all kinds of occasions that need to resist acid and alkali and organic solvents. Sealing, high lubrication non-stick, electrical insulation and good anti-aging ability, excellent temperature resistance (can be in the positive 250 ℃ to negative 180 ℃ temperature for a long time). Teflon itself is not toxic to humans. The use temperature is -190~250 ℃, allowing quenching and quenching, or alternating hot and cold operation. Pressure -0.1~6.4Mpa.
Teflon digestion tube characteristics
1. The appearance of pure white, smooth wall without hanging water;
2. High temperature resistance: use temperature -200~250 ℃;
3. Low temperature resistance:-196 ℃ can be maintained at 5%;
4. Can withstand 10000 r/min minutes;
5. The outer diameter of the PTFE digestion tube is 30mm, and the total height is 105mm, which is consistent with the size of the PP digestion tube 50mL;
6. Has extraordinary chemical resistance, can withstand almost all chemical solvents (strong acid, alkali, aqua regia and various organic solvents).

2. Teflon Flared Tube
Teflon flared pipe is a socket connection. Put a circle of detergent into the rubber ring nozzle joint at one end of the head, then cover the nozzle with a wooden board at the other end, beat it with a larger hammer, and push into the pipe to connect the two pipes. The flared tube is installed in place more firmly than the joint bonding, the joint is not easy to explode, and the installation efficiency is also higher.
The mechanical properties of Teflon flared tube are soft. It has a very low surface energy.
Teflon flared tube has a series of excellent performance:
High temperature resistance: long-term use temperature 200~260 degrees;
Low temperature resistance: still soft at -100 degrees;
Corrosion resistance: able to aqua regia and all organic solvents;
Weather resistance: the best aging life in plastics;
High lubrication: with a small coefficient of friction in plastics (0.04);
Non-stickiness: It has a small surface tension in solid materials without adhering to any substances;
Non-toxic: physiologically inert; Excellent electrical performance, is an ideal C- class insulation material, a thick layer of newspaper can block 1500V high voltage.
Teflon is called Polytetrafluoroetylene in English, referred to as Teflon, PTFE, F4, etc. Teflon (Polytetrafluoroethene) is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material has the characteristics of acid and alkali resistance, resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, Teflon has the characteristics of high temperature resistance, and its friction coefficient is very low, so it can be used as lubrication, and it has also become an ideal coating for the inner layer of easy-to-clean wok and water pipes. Can be used for pipeline anti-corrosion, high and low temperature resistance, corrosion resistance. Lubrication and other engineering, electronics, electrical appliances, aviation and other harsh environments.
3. high temperature resistant Teflon casing
The temperature resistance of Teflon is the use requirement that many people need to know. For high temperature resistance, Teflon can withstand 260 degrees all the time and reach 400 degrees in an instant.
Teflon has high temperature resistance and low temperature resistance. Teflon can reach -190 degrees when used for a long time, but it expands with heat and shrinks with cold. Generally, the safe and effective limit temperature is about -70 degrees.
Teflon is a special plastic with high temperature resistance, wear resistance, self-lubrication (extremely low friction coefficient) and chemical characteristics. It is a special plastic with corrosion resistance, strong acid and alkali resistance, and can withstand the effects of all strong acids (including aqua regia), strong oxidants, reducing agents and various organic solvents except molten alkali metals, fluorinated media and sodium hydroxide above 300 ℃. The chemical name is polytetrafluoroethylene (PTFE).

Teflon is a registered trademark used by DuPont on a range of its fluoropolymer products. It was invented and manufactured in a Jackson laboratory by Dr. Roy J. Plunkett.
Teflon is commonly known as "plastic king". It is a polymer compound formed by the polymerization of tetrafluoroethylene. It has excellent chemical stability and corrosion resistance (it is one of the best corrosion-resistant materials in the world today. In addition to molten metal sodium and liquid fluorine, it can withstand all other chemicals. It does not change when boiled in aqua regia, widely used in a variety of need to resist acid and alkali and organic solvents), sealing, high lubrication non-stick, electrical insulation and good anti-aging endurance, excellent temperature resistance.
