The disclosure relates generally to a cell culture apparatus and a cell culture method. One aspect of the disclosure provides a perfusion cell culture bag comprising one or more polymer films, having edges bonded together to form edges around an undivided interior compartment of the bag; first and second ports each formed in an exterior surface of the bag; first and second liquid-permeable tubes each extending into and in fluid communication with the interior compartment of the bag and operatively coupled to a respective port; and a third port formed in an exterior surface of the bag, the third port being in fluid communication with the interior compartment of the bag; wherein the first tube comprises a first inner support structure defining a central lumen of the tube and a first outer filter layer surrounding the first inner support structure.

Cell culture system

A coated fabric includes a reinforcement, a first coating disposed on the reinforcement, and a second coating disposed on the first coating. The first coating includes perfluoropolymer. The second coating includes perfluoropolymer and a silicone polymer in an amount in a range of 2 wt % to 30 wt %.

Modified perfluoropolymer sheet material and methods for making same

The disclosure is directed to a barrier structure including a fluoropolymer layer and a polymeric layer. The barrier structure has a chemical permeation breakthrough detection time greater than about one hour for hazardous chemicals as measured by ASTM F739. The disclosure is further directed to a method of forming the aforementioned barrier structure. The barrier material is designed to be suitable for construction of shelters, clothing, containers and other articles requiring barrier properties.

Barrier structure and method for making

The disclosure is directed to an article including a first layer, second layer, and third layer. The first layer includes a fluoropolymer having a first major surface and a second major surface. The second layer overlies the first major surface of the first layer and includes an adhesive layer. The third layer overlies the second layer and includes a polymeric material. The article has a burst performance greater than 200 N as measured by ASTM D751 and a chemical permeation breakthrough detection time greater than about one hour as measured by ASTM F739. The disclosure is further directed to a method of forming the aforementioned multi-layer article.
