Nutrient Agar Science Project Kit by Evviva Sciences

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.

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.

Works better than other brands!

The agar plates were shipped with care and the packaging held up well. Some of the plates I received in one box were contaminated, so I contacted the customer service email on the product. They responded immediately and informed me that they would be sending me replacement plates. Margaret provided great customer service and was very quick with her responses to my emails. I will be purchasing from Evviva Sciences again in the future because of this great customer service experience!

I ordered these for my online Microbiology class. All of them but one were fine. One of the lids were in pieces and broken. I unfortunately can’t go through the return process because I need them for my class. Very disappointed.

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.

This set worked so well, very easy to use, just use the sterile swabs provided and you will grow impressive samples. We swabed the backyard soil, floors, bottom of shoes, sink, toilet seat, fingers and toes and an unwashed apple. The kids were really impressed by the amount of microorganisms grown from an invisible stuff on the swabs. We also bought a microscope and were able to actually see all of the different types of microbes and fungi that grew on these dishes. My kids are 6.5 years old, they are now much more conscious about washing hands, good hygiene and washing food.

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

Good

Worked well for daughters science project . Was able to grow bacteria in the agar as per the experiment. Nice they come with agar already in the dish with the cover.

3 of the plates were contaminated and full of mold. Fortunately they were sealed in sets of 2 or 3 so the other 7 were usable

Half the plates arrived with black mold growing.
