Plastic (Polystyrene) Petri Dishes
Petri dishes can culture
molds or bacteria or act as a small enclosed environment for insects and plant seedlings or even as a display case.
These petri dishes are made from clear polystyrene and are sterilized.
We do not supply them with agar since different micro-organisms need specific nutrient agar;
so you would have to make your own anyway. Gelatin ("jello") can be used instead although it liquifies around room
temperature. Some health food, baking goods or oriental groceries do carry real agar though.
Some uses for petri dishes besides growing bacteria & fungi:
- Sample display cases or unique gift wrap
- Use with magnet & iron filings to view magnetic fields
- Use with filter paper for seed germination
