Snap ring vial 2 ml 12 x 32 mm large opening 6,0 mm

Snap-Ring vials have two glass rings at the neck of the vial that allows the use of a plastic snap cap or aluminum seal. While aluminum seals can be used, a polyethylene Snap Ring cap eliminates the need for crimping which saves time in the lab. When using volatile liquids, we suggest the use of polypropylene GC Snap Top caps to provide an airtight seal.
