The Chitogen product is differentiated by its structure, chemistry, and processing simplicity. It is unlike other products in the market today.


The Chitosan STF was developed to control pH, ionic charge and to increase adherence to bleeding tissues. The hemostatic fiber attaches to the bleeding tissue to form a stable clot. Once bleeding is controlled, the pad is easily removed by fluid irrigation.


The SoftSeal®-STF Pad is composed of millimeter sized fibers of chitosan which is derived from chitin, a natural biopolymer that is the raw material of crustacean skeletons. Chitogen specifies to its suppliers that its starting material is the Alaskan king crab shell.


In contrast to shrimp or other crustaceans, the king crab shell is more reliably processed and provides a fiber with very high molecular weight. The high molecular weight is a requirement for a finished product that possesses excellent biocompatibility and toughness for additional processing.
