Standard 100 x 15 mm petri dishes in optically clear polystyrene, supplied sterile in cases of 500. The shallow profile and uniform wall thickness make colony counting and plate photography repeatable between operators.
Sold as empty, sterile dishes — agar and media are not included. That keeps the plate suitable for whichever prepared medium your lab already validates, and avoids the shipment and shelf-life problems that come with pre-poured plates.
Who it is for
- Food and beverage plant microbiology labs running routine plate counts
- Environmental and water testing laboratories
- School, college and university teaching labs
- Compounding pharmacies and clinics performing sterility checks

Frequently asked questions
What size is a standard petri dish?
100 x 15 mm is the standard general-purpose size for plate counts and streak plates. Smaller 60 mm and 90 mm formats exist for specific methods; match whatever your validated procedure names.
Are these dishes sterile?
Yes, the case is supplied sterile and single use. Keep the sleeve closed until the plate is needed and discard after use.
Can I autoclave polystyrene dishes?
No. Polystyrene is a single-use plastic and will deform in an autoclave. Sterile dishes are used once; glass dishes are the reusable alternative for heat-based workflows.
Do you sell pre-poured agar plates?
Not currently. Our listing is for empty sterile dishes, which lets each lab use the medium it has already validated.
