Collaborative design efforts
Wilson Wolf and Trelleborg collaborated on the design for a permeable cell culture device
- They eliminated components, improved overall design, and decreased product cost
- Trelleborg molded a gas permeable membrane key to the cell culture process
- Trelleborg oversaw all molding, assembly, and packaging operations in its ISO 13485 Class 7 and 8 cleanrooms
- The design provides the easiest and fastest way to generate the most cells in the least space
- The G-Rex 100 Series set the stage for a complete line of cell culture products
- G-Rex is a patented FDA registered Class 1 medical device
How it works
The G-Rex proprietary technology leads to powerful therapies

- The G-Rex gas permeable membrane is contained in a four-component thermoplastic assembly
- The incubator is set in oxygen from ambient air and CO2 from the media is exchanged through the gas permeable membrane
- Cells obtain oxygen and nutrients on demand without the need for media exchange, shaking or rolling
- The cultured cells are collected by withdrawing 90 percent of the media volume and then removing the cells
