Analytical

Analyses of process fluid composition, determinations of particulate and bacterial levels, and other laboratory procedures are critical steps in manufacturing semiconductors. Fluid chemistries must be analyzed and kept on specification to maintain yields. For accuracy and repeatability, labware and equipment must not react with or contaminate the samples being studied or the reagents.

Containers

Reagents for analytical work as well as process fluid samples are held in containers of Teflon® PFA HP for protection against contamination. Because Teflon® PFA HP is unaffected by virtually all chemicals and solvents, containers may be reused time after time.

Tubing

Apparatus for wet analytical analyses may be interconnected with tubing of Teflon® PFA HP to help prevent contamination and assure test accuracy.

Labware

A full range of beakers and other lab equipment is available in Teflon® PFA HP. The resin's chemical resistance and purity help prevent inaccurate analyses.

Filters

Filters for lab-scale purification and clarification of gases and liquids have membranes of Teflon® PTFE. Because it has broad chemical resistance, Teflon® PTFE helps prevent contamination of fluids.
