30 Pack 90 x 15mm Plastic Bioresearch Sterile Petri Dishes with Lids

Exactly as described.

broke a couple trying to open them or put them together i forget the exact circumstance but user error , price is right cant complain just wishful thinking i’ll be more careful lol. better than breaking 2 glass ones ,everyone’s wyling on those tickets everywhere for what they are, i’m cool. quick ship n these seemed pretty sterile , still wiped em down but they do what they’re supposed to just fine . lightweight and veryy affordable esp in bulk. thank you 5/5

These arrived unbroken and I had no issues with sterility. They all were sterile upon arrival. I use these exclusively for mycology and will buy more.

Qiuttnqn - 30 Pack Plastic Petri Dishes with Lids,90 x 15mm I bought these for looking at insects and etc with my stereo microscope. Clarity is good straight out of the package. I tend not to be a waster, especially with plastics, so hand washing and reuse is my goal. However, some things just shout "I aint washing that" like, ahem, certain creepy crawlys that gross people out. But when I do wash them they need to be soft cloth dried immediately or they get water spots all over. They are not heavy duty, they are light weight plastic. Good for my particular use or for crafty or funsy kid projects. My sister use to work in a lab, these are no where near that quality level of petri dish. But my use these are excellent.

Very good for crafts, but do not expect these to be sterile or autoclavable! They cannot be used as functioning petri dishes!!

The petri dishes feel a bit flimsy, but they are sterile and do the job. For the price, I can’t complain. They work fine for my needs, just don’t expect them to be super durable.

All came intact, and were perfect for our science party, made petri dish jello to look like agar with bacteria(sprinkles). Size was perfect, like real petri dish. Lightweight because it is plastic. Clear and easy to clean.

I like them! I'm using them to separate Lego pieces!
