Our Teflon®  spin coaters have been precisely machined from solid virgin PTFE Teflon-NXT® or Dyneon™ TFM™. This semiconductor-grade material is nearly impervious to all chemical attack, and can operate at very high temperatures. All lids are transparent and chemically resistant, and are secured using ECTFE-coated 316 Stainless Steel screws in non-wetted areas.
All of our TFM   spin coaters are considered metal-free and therefore compatible with all solvents, strong bases and acids even HF, HBr, HCl, et al. If you intend to continuously, and for long periods of time, exceed 100°C in the process chamber, please indicate this requirement when specifying a system.
Near zero porosity means a glass-like finish and no chemical memory in the process chamber of the  spin coater!Teflon is a registered trademark of E. I. du Pont de Nemours and Company. Dyneon and TFM are trademarks of Dyneon, a 3M Company.
