This method is particularly appropriate for aqueous, oily, and alcoholic remedies, and also for products that can be dissolved or emulsified. Samples are filtered by way of a pore dimensions that traps any opportunity microorganism cells in the solution.
Neutralization: In case the item has antimicrobial properties, a neutralizing agent might be extra to the media to counteract these consequences.
The cultures are incubated to get a duration of 14 times with intermittent observations. The growth of microbes while in the media is analyzed.
This doc discusses sterility testing protocols for pharmaceutical products According to Indian Pharmacopeia guidelines.
