Polytetrafluoroethylene (Teflon) beakers are also called PTFE beakers, Teflon beakers, F4 beakers, anti-corrosion beakers, high-temperature beakers, and processed Teflon (Teflon) beakers are a common laboratory Utensils, beakers are cylindrical, with a notch on one side of the top, which is convenient for pouring liquids.

the bottom is flat and can be heated, and it is often used to prepare solutions and as a reaction vessel for larger quantities of reagents. PTFE beakers have excellent corrosion resistance, strong acid and alkali resistance, no water absorption, and almost all solvents and chemicals do not work on its own inertness.

the polytetrafluoroethylene (Teflon) beaker is a kind of laboratory instrument produced by using its characteristics. the processing method can be processed by equal pressure method or finished by fine turning.

Isobaric processing is to put PTFE material into a flexible mold, seal the entire mold, use fluid pressure to pressurize, maintain pressure, and release pressure, and then take the mold out of the container and take out the prefabricated green body from the mold. Then put it into a sintering furnace for sintering.

the sintering method is the same as that of the direct cold-pressed product, but the processed preform is closer to the actual product sample, which can save a lot of raw materials, but the mold is complicated; corresponding to the beaker processed by turning and milling, it has better firmness and durability, and the specifications can be processed on demand, but the material loss is large.
