Best Caps!
I have officially tried all of the caps available for the dram bottles and the Poly Seal Caps are definitely the best! Will be ordering only these caps in the future!
Our screw thread vials are designed with a continuous thread "CT" finish, permitting a positive seal, ideal for a variety of uses including laboratory or manufacturer's use. These vials are available in a wide range of sizes in both clear (flint) or amber, and packaged in attractive, white low-particulate cardboard boxes. All glass vials may be ordered without caps, caps attached or caps packed separately. Choose from our standard black polypropylene cap with a polyethylene foam liner, our highest quality, chemical resistant Teflon® liner or a black phenolic Polycone closure.
