10 custom made to order Petri dishes with a malt extract agar base. Basic recipe is 15g/L of light malt extract, 1.5g/P yeast extract, and 15g/L of agar. Light malt extract recipes can form some sediment in agar but does affect growth. High nutrient recipe is 20g/L of malt extract, 2g/L yeast extract, and 15g/L of agar. Low nutrient is 10g/L malt extract, 1g/L yeast extract, and 15g/L agar.
I recommend standard for this media type.
The dishes are heat sealed in shrink plastic in set of 10. If you want sealed individually please purchase Seal Package and select options for each set of 10 dishes. Each set of petri dishes includes parafilm.
Tip of the Cap disclaimer: These are custom made to order Petri dishes, you choose the media for your purposes. Different media will perform differently with different strains and growth type is not predictable with thousands of combination options. Random dishes are available with multiple media types to see what your cultures prefer. Please explore different media types before committing to a large number of Petri dishes your cultures may not perform well on. Petri Dishes are sealed in sets of 10, open with care. You can remove dishes singly from packaging to keep remaining dishes sealed from contamination. Please check packages for any issues with the product or contamination upon arrival. Store plates in an upright position in a cabinet along inner wall for consistent temperature, or a cooler to keep temperatures constant. I do not recommend storing plates for more than a month or in the refrigerator.
