Once you put your critical or caustic sample inside the bag, how do you close it?
The standard protocol has been to use a clamp made of some other material, or to purchase and operate expensive heat-sealing equipment. Both of these solutions come with a rash of problems and are inconvenient to use. American Durafilm Co., Inc. has finally solved the problem with the first and only 100% FEP Duralok™ technology.
This custom addition allows any bag made from FEP or Kapton® film to be transformed into an easy-to-use and resealable container for use in labs or in the field for sampling. Once closed, the seal is liquid and airtight, but not rated for pressure. There are no special tools to operate or expertise required to ensure a proper seal. Duralok™ brings the simplicity and convenience of conventional sandwich bags to the FEP and Kapton® bag market.
