PTFE is ideally suited for the labware application because of its legendary resistance to just about anything including strong acids and bases. PTFE labware is also resistant to steam and has a temperature range of use covering the range of -200°C (-390°F) to +300°C (+570°F). Because of the three dimensional structure of PTFE at the molecular level, it is essentially intractable in any solvent, therefore explaining its unique resistance to dissolution in most solvents or strong acids and bases. The helical structure of the polymer chain, which is literally "sheathed" by the F atoms means that more chemically vulnerable carbon-carbon bonds of the chain are fully protected. Because of the very high purity of the PTFE starting material all products exhibit extremely low levels of extractables, even at elevated temperatures. The legendary non-stick properties of PTFE give it yet additional advantages for use in the laboratory.
A PTFE magnetic stir bar is a device widely used in laboratories and consists of a rotating magnet or a stationary electromagnet that creates a rotating magnetic field. This device is used to make a stir bar, immerse in a liquid, quickly spin, or stirring or mixing a solution, for example.
Chemically resistant PTFE beaker is isostatically molded from virgin PTFE and machine finished to give a smooth surface for ease of cleaning and to eliminate contamination. PTFE beakers with pouring spouts are virtually immune to chemical attack, only attacked by some fluorine containing compounds at very high temperature and molten alkalis metals.
PTFE measuring cylinder is a substitute to glass measuring cylinder, it can be used to measure both acid liquids and alkaline liquids. PTFE has advantages of surface finish, low coefficient of friction, lubricity, high working temperature (up to 260º C), excellent dielectric properties, corrosion resistance.
PTFE crucible is made from chemically-inert ptfe, a synthetic polymer that can be heated to 270ºc without distortion. Crucibles display excellent chemical resistance and even heat transfer. The crucible is resistant to high temperatures and virtually all laboratory chemicals with machine-finished surface for easy cleaning.
