Stopper, 7 ID x 13 mm OD Mouth, Natural Red, Rubber, Snap-On Style, 40 Durometer, Autoclavable, Provides Maximum Sealing, For Vials with a Blow-back Glass Finish
This design provides maximum sealing for vials with a blow-back glass finish, which is a small ridge on the interior of the vials neck. The snap-on stopper locks into the blow-back ridge, providing a tight seal and keeping the stopper from backing out. This style is not recommended for vials with a straight-walled finish. The blow-back feature is typically found in vials from North American manufacturers.
