When preparing nutrient agar plates, you will need to supply enough nutrient agar in order to have a successful batch of petri dishes.
These calculators will help you determine how many dishes you can make with liquid or powder nutrient agar. You can also calculate how much agar you will need to make the desired number of plates.
Calculations are based off of products sold at Heath Scientific.
Difference between Powder and Liquid Agar
Nutrient Agar usually comes in powder or liquid form.
Powder form is usually less expensive due to shipping and storage costs; powder agar needs to be made into liquid form before it can be applied to petri dishes.
