How To Use Aluminum Hydroxide Gel
Feb 16, 2022
Alumina gel generally refers to an aqueous suspension of aluminum hydroxide. The gel is prepared by reacting aluminum chloride with ammonia water, washing off ammonium ions with a large amount of distilled water, and then autoclaving. Can be used for the preparation of vaccines. So let's take a look at how to use it.
Aluminum hydroxide gel is a white viscous suspension gel liquid; the thin layer is translucent, and a small amount of water can be removed after standing; it has a slight reaction when it meets red or blue litmus paper, and it does not meet the phenolphthalein indicator solution. Red. This product is a suspension-type gel liquid formed by dispersing small colloidal particles of aluminum hydroxide in water. The aluminum hydroxide content should be 3.6 to 4.4 percent (g/g) calculated on alumina.
Regarding its quality inspection, the acid production rate, chloride content, sulfate content, heavy metal content, arsenic salt content and aluminum hydroxide content should be determined according to the requirements of the "Pharmacopoeia", which are all in line with the "Pharmacopoeia".
Reminder: For your own safety, before using the aluminum hydroxide gel reagent, please take precautions, such as wearing lab coats and gloves. The storage temperature is 2-8 degrees Celsius.
