3.Others performance

3.1 Surgical Catgut suture meets standards of CFDA and EP and USP for absorbable surgical sutures.
3.2 WEGO Chromic Catgut contains a chromic salt solution to delay absorption, so absorption period is longer than Plain Catgut.
3.3 WEGO Catgut is sterilized by Gamma ray, so sterilization is totally complete.
