Twenty 90mm dishes with lids - 75c each

90mm diameter, 15mm external depth, 12mm internal. Plastic with safety lids. Pack of 20 for $15.00.

The everyday petri dish. Seed germination, crystal growing, sorting small specimens, holding a sample under a magnifier, mixing tiny quantities - the uses that do not involve culturing anything.

These are not described as sterile. The supplier calls them plastic dishes with safety lids and says nothing about sterility. If you are culturing bacteria or fungi, buy the sterile pack of 100 instead - a non-sterile dish means you are growing whatever was already in it as well as what you put there, and the result is not a result.

If you are culturing microbes in a school, the supplier provides no growth medium and no handling guidance with these. Follow your own state or system's guidance and talk to your lab technician about what may be cultured and how plates are disposed of. We are not going to write that policy for you.

For everything that is not microbiology, twenty at 75c each is the cheap and obvious buy.

FAQs

The supplier does not say they are, so treat them as not sterile. For culturing bacteria or fungi, buy the sterile 90 x 15mm pack of 100 instead.
Yes, and that is the common school use. Germinating seeds on damp paper does not need a sterile dish.
Use the sterile dishes. A non-sterile plate already has an unknown population on it, so anything that grows tells you nothing.
No. No growth medium comes with these, and none is offered in this line. Ask us if you need agar plates or medium.
They are inexpensive single-use plastic. School microbiology plates should be disposed of according to your school's procedure, not washed and reused.
