QWORK Glass Petri Dish Petri Plates with Lid, Thicken, 60mm x 18mm, 5 Pack

Arrived on time and in good condition; the individual dishes where individually packaged in bubble wrap in a perfectly sized shipping box. The dishes arrived very clean; very nice petri dishes.

For watchmaking they work great, for storing or cleaning parts, the lid is very loose.

I'm not sure whoever makes these has actually ever seen a real petri dish before. There's zero seal with a large gap all around the flimsy glass. Avoid these.

well, the materials are great, but the lid has a lot of edge clearance... I did tape them closed, and it worked out just fine... But I would really prefer a more fitted lid.

One lid arrived broken. Dishes all survived the pressure sterilization. Lids are quite a bit larger than the base leaving a large gap. A bit more tricky to seal with parafilm than plastic dishes. All in all, about what I expected for the price. Micropose now sells reusable polypropylene dishes, will probably buy those from now on.

Bought these for the price. Giving 5 stars because they appear to be good quality glass - they autoclave fine. However as other people have noted there is a sizable gap making them ill suited for agar plates or do plan on using a lot parafilm to ensure they're sealed. I found it a pain and I found a pack of "20Pack Round Clear Frosted Plastic Bead Storage Containers Box Case with Screw Top Lids,Cylinder Stackable Bead Containers for Make Up,Eye,Pills,Gems,Beads,Jewelry,Small Items,2.6x1 Inches" on Amazon for twice the price but much better for mycology and they're autoclavable - although twice the price you get 4 times as many making them a better value.

Some things are, or they are not, as simple as "As Expected" and that says it all - these are very much in that category, and the price was a pretty good deal too.

These petri dishes were actually a great deal, slightly thicker than your average plastic petri dish, but not as premium feeling as PYREX branded dishes. To contrast that you don't pay anywhere near what a single Pyrex dish would cost for this set, so I am very pleased with my purchase! I bought with the intention of painting the underside to study the way different liquids react to vibration/sound/frequency. Then recorded the visuals on 120 black and white film- a mixture of science and fine art :). Would gladly purchase again if needed! Highly recommended them!

The lid of the petri dish is not a lid but a larger petri dish, and the difference is so great that they do not seal tightly and cannot be made airtight in any other way either. It's completely pointless to try to do a protected cultivation in these "petri dishes with lids". What a joke. Do not buy! You can tape two plates together instead. That's better.

These dishes are still fully intact and working well even after 4+ autoclave cycles, they are sturdy and were packed well.

Materiale buono, imballato bene, arrivato integro.

Three of the QWORK Sterile Glass Petri Dish Petri Plates with Lid were broken when I received these items.

Boites en verre parfaites pour mon blob.
