Evviva Sciences Nutrient Agar Petri Dishes Science Project Kit, Pre-Poured Agar Plates for Science Experiments, with Experiment eBook

Anytime a gift giving opportunity arises, my grandson requests these petri dishes. From the culture, to growing bacteria and being able to look at it under the microscope, is a great learning experience for him. He loves to learn and discover new things and the Evviva Sciences Nutrient Agar Petri Dishes is an age appropriate resource that fosters learning plus it's safe to use. I highly recommend this product.

No contaminated plates in my order. The expiration date is over a year from now, which is much longer than any other petri dishes I've had. I appreciate the information about refrigerating them and "thawing" them for an hour. Pictured with my review is a plate exposed to outside Ohio air for one hour on a calm day (very low wind), taped shut, and then held in a plastic baggie for several days in a dark, warm (70s°F) area.Happy with this product.

These petri dishes were not sterile as listed in the description. At least 2 were growing visible mold when I attempted to use them.Updated review and rating from 1 to 4 as the seller reached out and sent a full refund. Apology accepted!

We ordered these for a Stem fair. We received them and some had stuff already growing, we reached out and they replaced the product with no issues. Had a lot of growth after our swabs as well, so these Petri dishes are definitely a good product to use. The instructions were very simple to understand and you didn't have to do much to get the results.

Problem. Could not use in lab because mold was already growing on agar dishes.

I used these petri dishes for an experiment for a bio paper I had to write in class, and these petri dishes definitely served their job and were very affordable! definitely recommend if you have to an experiment for school on a budget !

Followed the instructions, swabbed some really gross stuff, and two failed to grow anything. They should all have grown something. The swabs for the two failed plates were from some very dirty and gross sources

These were perfect for our sons science project! He grew bacteria to see if the 5 second rule was true. He ended up winning first place for his grade! These were perfect!
