Which Openings the No. 2 Fits
A tapered stopper seals where its side meets the rim, so it suits an opening wider than its 13.0 mm bottom and narrower than its 16.5 mm top, such as the mouth of a small test tube. Push it in with a slight twist until roughly half its height is inside. If it slips right into the neck it is too small, and the No. 3 is the next size up.
