Evviva Sciences Potato Dextrose Agar Petri Dishes - Prepoured Potato Dextrose Agar (PDA) - for Mushrooms, Home Test Kit, or for Science Fair Projects, Petri Dishes with Agar

These came in sealed bags- 2 sealed dishes, then 3 sealed dishes on one bag as others stated. My order was for 10. They have a little moisture but not dripping wet like some have reported. No contamination after leaving them in room temperature for three weeks. Used two already with perfect results. Time to use the rest up or risk degradation.As with all these agar filled dishes, I wouldn't refrigerate as that will condense liquid and make a mess. We always refrigerate, but in this case it's a moot point considering the shipping company has them in their truck for hwo knows how long on adverse conditions.My only disappointment is that these should be individually sealed, or at least sealed in pairs seeing it's a "lot of 10". Once opened in front of a laminar flow or clean still air box, using them is really your only option or one runs the risk of contamination.I'm about to order a second batch hoping for similar results. So far, I would recommend these under the conditions stated above.

Used for settling plates and worked well.

For 30 dollars you would think these are great. Cheap, thin plastic. 5/10 were cracked upon delivery. Company will not respond. Within 48 hours there was contamination in the plates. Don’t waste your money here

Let me tell you, these prepoured agar plates are like the red carpet for microorganisms, giving them the VIP treatment they deserve. First off, the convenience is off the charts, just pop the lid, and you've got a perfect microbial buffet ready to go! Microbes strut their stuff on these plates. It's microbial fame in the palm of your hand. And the best part? The potato dextrose agar provides a nutrient-rich environment that even bacteria couldn't resist. It's like offering them a five-star meal. I give them to all of my neighbors for fun.

These plates arrived with lots of liquid in them. Some of the plastic was cracked. About half of the plates looked to be contaminated with small white spots and the smell when I opened the box was horrid.. Do Not Buy ..

We originally ordered agar petri dishes from another company but *many* of those dishes arrived wet and already growing bacteria/mold. We needed another set of agar petri dishes quickly for a science project and these arrived on time with all dishes usable and intact!There was a note included with the product that sometimes dishes get damaged in transit, with a number to call if necessary to arrange for replacement but we didn't need to use it. The quality of these dishes was so much better than the others we ordered! Also appreciate that the company proactively included information for customer service just in case.

I used these to test a few rooms in my house for airborne mold. Leave them open in a room for an hour, incubate them for a couple of days, then shine a light through them and count the number of mold colonies that have formed.I was able to rule out any serious mold problem in my home because almost no mold colonies formed on any of the plates. These were fast and cost-effective compared to "test kits" for home airborne mold spores.

Came fast,good shipping,they seem as advertised. One dish did come with contamination,along with one separate disk cracked across the agar side. Not contaminated shockingly. I'm thinking its probably a fluke thing with contamination. Probably shipping for the crack. Bad time of year to order,plus cv19. Hopefully no others arent sterile. They should be showing by now if they weren't.Will update when I hear from support about what they are going to do. Minus the issue they seem ok.Update: Spoke with customer service. Very fast response and kind people. Free new 5 pack on its way.
