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

Great small storage containers for a cheap price. Hold loose beads, or nicnacks great. These are actually awesome. Got them for being able to sanitize stuff and they hold up in the pressure cooker since they're PP5.

Finally a fairly priced option for these. If you are looking for the adapted screw top Petri dishes, this is them. And for far less than the previous vendor that keeps jacking the prices up, and for far fewer items. If this vendor maintains this price, they will have a stack of cash in short order. These are PP5 on both the tops and the bottoms. They do just fine in PC Sterilization. Clear enough to see any culture you are growing easily. Absolutely perfect for "No Pour", petri dishes. I will be ordering many more of these in the future.

These PP5 bead cups work well as reusable Petri dishes. You can use them for no pour agar, and they eliminate the need for parafilm. Sturdier than condiment cups, and less plastic waste. It's an economical and eco-friendly alternative. They are slightly more opaque than regular plastic Petri dishes, and I would suggest using food color in your agar for better contrast and clarity. Overall I am very pleased with them. UPDATE: The clarity is fine without any food coloring. They're airtight and have become one of my favorites.

These were exactly what I needed they're the perfect size to be able to pour your beads into and be able to get your needle into the jar and get out the amount of needles you need so you don't have to dump them into anything else the only thing I would change or love that would be better is the lids weren't as tight as I would like them to be. It seems that over time just moving them from place to place around the house that the lids will work their self loose and you definitely don't want beads all over the place. So if you just occasionally check the tightness on them they work well.

I used these for my Lion's Mane, Reishi, Blue oyster culture dishes. Not traditional use but works well and can handle being pressure cooked!

These are really nice containers. I use them as petri dishes for no pour agar. Very durable and stood up well in the autoclave. This speaks volumes to the durability of these containers.

Use as reusable solid media plates. Plates don’t dry out, don’t appear to require parafilm (haven’t noticed contamination issues). They do become less clear after autoclaving. No issues with caps and bottoms working together.

Exactly what’s needed for no pour agar. It makes it so simple to create your own plates you pour first and then you pressure cook them with the lid slightly loosened, sterilizes them safely and then you just screw the lids down snug when you take them out. The craziest part is they are cheaper than the single use Petri dishes despite being reusable, and you don’t have to fiddle with sealing them in parafilm, just screw it closed.

Sehr praktischer Ersatz für Petrischalen. Etwas zu teuer da Versand aus USA.

Nothing to dislike, they are fantastic.

I use them as reusable petri dishes and they are air tight, preventing contamination. I've got one from a few months ago that is still clean.

They are not so clear so it is hard to look through them. But they work Good in my autoclave!

They are not screw on lids
