Product Description
Dropping a separate liner from the closure removes one more thing that can shift, swell or contaminate a sample. These linerless polypropylene screw caps seal directly against the bottle finish, giving a leak-resistant closure that is simple to clean and reuse.
This listing is for Wheaton catalog number 239512-04: Linerless Leak Resistant Screw Cap, Blue, 28-410, Case of 72.
