It took two decades of manufacturing skill and extensive laboratory use to come up with TSCD II, a strong and consistent sterile weld with better level of speed and assurance in sterile connections. The safe, quick, and strong welds keep a functionally closed system. The TSCD II is easy to use due to its good features like automatic wafer feed, LCD display, and data capabilities. The sturdy design and the durable clamp mechanism make the device an elegant choice for intensive use. It can join any combination of wet or dry tubing due to its design. Some of its applications are Leukoreduction, Component pooling, Component aliquoting, Collection set modification, Cell washing and freezing; quality control sampling and apheresis set modification. Other applications involve closed system PVC tubing connections.
