Application
Adjuvant in immunizations
General description
Alhydrogel is a stable gel which has a uniformly high adsorption capacity and which can be repeatedly autoclaved without losing any of this adsoprtion capacity. As the product itself is a poor heat conductor, care is necessary during autoclaving and constant stirring is advised.
