Overview
Beaded edges give these Pyrex petri dishes greater mechanical strength and set an equal gap between the bottom and the cover. That spacing reduces the capillary action of condensed moisture along the sides.
The reason to buy is durability in labs where sterilization is routine: the glass is unaffected chemically or thermally by common methods. Color coding sorts tops from bottoms, and bottoms carry a triangular reference mark for serial dilutions. The limitation is the lid, which gives no gas-tight seal.
Who it's for
School and clinical labs plating cultures and running serial dilutions that rely on autoclaving between uses. Labs wanting disposable sterile dishes, or sealed containers for transport, should look at plastic or lidded options.
Pros and cons
- Reusable glass dishes
- Withstands wet or dry sterilization
- Beaded edge adds strength
- Blue and white enamel for sorting
- Cover not airtight
- Glass can break
- Needs washing and sterilizing
- Weight and bulk of glass
Performance notes
The beaded edge sets even spacing between the lid and the base, which cuts condensation creeping down the walls. Glass resists the chemicals and temperatures of routine lab sterilization, so dishes can be cycled through repeated runs.
