A teflon liner is a chemically inert material used in the inner vessel of a hydrothermal autoclave reactor. This white and shiny polytetrafluoroethylene (PTFE) is resistant to alkali and acid, but can be damaged when exposed to temperatures above 200 degC.

teflon liners are manufactured in a variety of sizes and thicknesses, including a very thick one that can be fitted to the lid of a hydrothermal autoclave for maximum strength and safety. They can also be constructed to be a tank liner, cell cover, or expansion joint.

High Temperature Caps & Open Top Bottles

The teflon liner in these caps is triple-extruded to provide resilience and deter back-off when the cap is screwed on. The polyethylene backing also provides good flexibility for handling bottles and is a great choice in applications where the product is frequently moved around or handled. They are sterilized at up to 180 degC and have a 0.22 um polytetrafluoroethylene (PTFE) hydrophobic membrane for sealing. They can be ordered in bulk packs or attached to the lids of organic vials. They are available in convenient lab pack quantities as well. They can be purchased with either a closed or an open top closure. These are ideal for sputum specimens or any application where the contents are likely to be disturbed.
