What it’s for

Talking, or just breathing, over an open stopper is the main way anything gets into a vial. A mask for the two minutes of mixing removes it.

What to check in the listing

Any three-layer mask with a nose wire does the job; the 'medical' or 'type IIR' grade is a nice-to-have, not a need. One box is years of mixing. Put it on before you open anything, not halfway through.

SterileNoSterile means individually sealed and sterile until opened; anything that touches the inside of a vial or your skin should be.
