Don't use actual glassware for anything related to HF. Additionally, anything tht uses HF, especially staining solutions, should be copper free. Experience has shown that even trace amounts of copper after a thorough cleaning can contaminate etching solutions.

I love fluoropolymers since they work with just about anything but they can be expensive. Polypropylene works just as well in many cases. HDPE/LDPE probably next in order of general preference.

Of course, make sure to look up compatibility before assuming that a chemical is safe to use in a given container. A quick check chart can be found here.

Fluorinated plastics can be useful in a number of situations. They tend to be very clean, are reasonably heat resistant, chemically resistant, and have many other desirable properties. Depending on the application, PTFE (Teflon), PFA gets used for wafer boats. See the Dupont website for a nice comparison chart.
