2.7.3 RHC and RHC/EGF freeze-dried dressing rehydration time
RHC and RHC/EGF freeze-dried dressing solubility tests were performed by using physiological saline. In short, we dissolved RHC and RHC/EGF freeze-dried dressing with 300μl of physiological saline. Determine whether the liquid can be sufficiently dissolved by the degree of liquid clarification, and record the dissolution time. All these physical measurements were made in triplicate at 25℃.
