Microlink® White Open Top Caps, With Polypropylene / Silicone / PTFE Liners, Wheaton | DWK Life Sciences

White, open top, autoclavable cap with ultrasonically bonded liner. Ideal for storage and containment of volatile solvents, sensitive compounds and corrosive chemicals. Available in convenient Lab Pack quantities as well as larger Case Packs.

These autoclavable caps for use with biological media, volatile solvents, corrosive chemicals, and sensitive compounds.

Microlink® Closures consists of a liner ultrasonically welded into a polypropylene cap. The liner consists of a layer of polypropylene (used for welding to the polypropylene of the cap) and a layer of silicone rubber (used for taking up imperfections on the vial surface) and then a layer of PTFE or polypropylene as the sealing surface. This welded bond provides a superior closure system, maintaining a seal through multiple cleaning and/or autoclaving operations. The use of a low compression set silicone is ideal for the storage of samples and sensitive materials for prolonged periods of time, over wide temperature ranges. PTFE or polypropylene film on the exposed face of the liner imparts an inert, highly chemical resistant surface ideal for the containment and storage of volatile solvents, sensitive compounds and corrosive chemicals.

• Welded bond between cap and liner maintains seal integrity through multiple autoclaving; no glue contamination
• PTFE or polypropylene on the exposed liner face is inert with most solvents and sensitive materials
• Low modulus (soft) silicone creates a superior long term seal
• Autoclavable- Sterilize by chemical or gas
