Stoppers

Plug-style needle closures White Polyethylene Designed for shell vials Economical

Complete Coat Stoppers are completely coated with a fluorinated polymer that has barrier properties similar to PTFE. The fluorinated polymer coating is the only material that comes in contact with the sample.

Ultra Pure Lyophilization Stoppers are made from a bromobutyl rubber compound containing the highest level of chemical purity. These stoppers demonstrate a very low level of moisture absorption and are ideal for most lyophilization applications.

The hollow stopper is light in weight, yet very strong to reduce chipping and breakage, thus minimizing replacement costs. A barrel-shaped head means it is easy to clean and even easier to rotate in or out.
