The smooth, transparent glass provides high light transmittance for easy content visibility. The tear-off caps, rubber stoppers, and glass vials fit precisely together.  They create a tight, secure seal that prevents leakage and keeps the contents secure.

Frequently Asked Questions

What comes in each set?
Each set is one 20ml clear glass vial, one gray 20mm rubber stopper and one blue flip off cap. Choose 10, 25 or 50 sets.

Are these vials sterile?
No. They’re new and clean, but not sterile.

Do I need a crimper?
Yes. The cap sits on by hand, but it won’t seal until it’s crimped. Our 20mm flip vial crimper presses it tight in one squeeze.

Can I use a different cap color?
Yes. Our 20mm flip off seals fit these vials and come in blue, red, black, grey, green and yellow. Use them to sort vials by batch or contents.

Can these vials go in the fridge?
Yes. The borosilicate glass handles refrigeration and heating.
