Don't use actual glassware for anything related to HF. Additionally, anything that 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.

Bottles

Fluoropolymer

Nalgene makes PFA bottles with ETFE caps. They are somewhat common on eBay. Example dealer here lists them as “Nalgene* Narrow-Mouth Bottles; Teflon* PFA screw closure”.

Entegris makes similar FLUOROPURE brand bottles. Product sheet here.

Polypropylene

Misc Fluoropolymer

Enteigris Fluoroware are the majority of fittings you'll find on the surplus market

Sani-Tech West makes some nice PFA vessels for pharmaceutical industry
