I am going to order some amber glass bottles from Fisher for
storage of photoresists and electron-beam resists (primarily PMMA in either
anisole or chlorobenzene). There are a variety of cap options. Can someone
recommend which is the best cap material for our applications?
Options are: Poly-Seal*-lined Closures, Polyvinyl-lined Closures,
Rubber-lined Closures, or Teflon* Faced PE-lined Closures.
