"Here," Gavin Lin pointed to the sulfathiazole sodium salt that had been filtered to remove impurities and excess sodium hydroxide solution, and said, "These remaining substances are sulfathiazole sodium salt. Just put them in a drying oven to dry them and remove the moisture in the middle. After they are completely dry, they will become pure sulfathiazole sodium salt powder."

"Then, according to a ratio of four to one, take four parts of distilled water and mix them with the pure sulfathiazole sodium salt powder to obtain the sulfa injection."

"Is it that simple?" Lin Zhiyuan, Lin Xinhong and his wife, and Lin Jiangnan all looked at the handful of wet powdery substance in disbelief.

"Well, it's that simple. In an emergency, you can directly use sulfa powder to prepare sulfa injection for use." Gavin Lin said, "But if you want to produce it in large quantities, you still have to strictly follow the pharmaceutical specifications of Western medicine to avoid secondary contamination caused by accident during the preparation process!"

Lin Zhiyuan nodded, turned around and looked at Lin Xinhong and his wife and Lin Jiangnan seriously, "This is the foundation of our Lin's National Medical Hall's future survival. You must keep it strictly confidential and no one can reveal it."
