How will you prepare 0.5 percent of agar gel?

Answer 1

To prepare a 0.5 percent agar gel, measure 0.5 grams of agar powder and add it to 100 milliliters of distilled water. Heat the mixture while stirring until the agar completely dissolves, typically around 85-90°C. Once dissolved, allow the solution to cool slightly before pouring it into molds or petri dishes to solidify. Ensure to sterilize the agar if necessary, especially for microbiological applications.
