Our unique stretching system enables uniform stress loading due to the materials and methods employed and the shapes of stretch chambers. The STREX Cell Stretching System is designed to achieve stretching in a single, parallel direction, with only a very weak secondary load. Research has demonstrated that the STREX system enables highly reproducible cyclic stretching over prolonged periods at ratios of 1 – 20%. (Ref) Naruse. K., et al. (1998), Oncogene,17:455-463.
