Regarding Ultrasonic mixing...

My Boston Rounds are thick glass. I've accidentally dropped two into our porcelain kitchen sink without breakage or even a chip. One was full and the other empty. Both had the cap on.

I have wondered whether glass or LDPE plastic made a difference in UC steeping. Anyone compared both? Seems like glass wouldn't pass the vibrations as well as LDPE.

Definitely don't use plastic, not worth the concern of leaching.

I hated the UC for "steeping" eliquid, but the UC has found many great uses around the house! hope it works out for you

Here's the answer as to which type of plastic bottles are safe for use with liquids.
Which Plastic Containers Can I Safely Use?

Type 4: Low-Density Polyethylene - Safe
Frozen foods packaging and condiment squeeze bottles often contain Type 4 plastic because it is flexible and resistant to solvents. Type 4 plastic does not contain any known harmful chemicals. Low-density polyethylene containers may have the symbol "LDPE" on them.
