100-count

What it’s for

Lets you pre-draw a syringe and keep it capped and clean until you need it.

What to check in the listing

Only useful if you're capping a filled syringe. Check the cap matches your tip — luer-lock and luer-slip caps are not interchangeable.

Needle connectionLuer-lockNeedle connection is how the needle attaches. Fixed means it is built in (least dead space). Luer-lock screws on and cannot pop off. Luer-slip pushes on. None means there is no luer fitting at all — a pen needle screws onto the pen's own thread. Glossary

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