30 Pack Petri Dishes with Lids,90 x 15mm Clear Petri Dish for School,Laboratories,Science Art Projects,Storing,Seeding and Biohazard Theme Party

Working in a laminar flow hood, these gave a 90% contam rate on these dishes I poured 120 of them ,0% contam on the cell treat dishes I used in the same pour. Leads me to belive these plates where not sterile from the beginning. highly disappointed,I wasted the money on 4 packs of them

Some were good and some were bad at fitting flat without air exchanges between the lid and base. If the plastic was a little thicker and the quality control was a little tighter I feel like they would work just fine without the need for sealing tape.

You'd save more buying larger quantities, but this isn't a bad deal at all.They look nice, hold up well enough for what I'm doing, and the top and bottom are very clear and easy to see through.

A little flimsy but at this price easily replaceable

Thin plastic, which wouldn’t be a problem if the packaging were better. All of these were unusable and now I’m left with a bunch of broken plastic. Would not recommend whatsoever.

Wouldn't buy again.....

Used these to make jello agar plates for lab week

These are super thin and half were broken. Don’t waste your money.
