Can I get a sample?
Evaluation units ship on a quote. Freight and commercial terms stay off the catalog.
How do I pick wet-end materials?
Open the materials window. Send medium, concentration and temperature — we confirm on the quote.
Why does a PTFE diaphragm need a backing?
PTFE is almost chemically inert but creeps under cyclic load. FKM or EPDM behind it carries the stress. The process sees only PTFE.
