Overview
A beaded rim runs around this clear glass dish, adding strength and spacing the cover from the bottom to reduce moisture creep. The cover is marked in blue enamel and the bottom in white, with a triangular reference point on the bottom.
Reusable glass cuts waste for labs that sterilize routinely, and the color coding speeds sorting. The cover is loose rather than sealed, so it is for ordinary culture work, not airtight storage.
Who it's for
Microbiology and teaching labs that wash and sterilize glassware between uses. Labs working with disposable plastic dishes or sealed storage need a different product.
Pros and cons
- Reusable borosilicate style glass
- Withstands repeated sterilization
- Color coded cover and bottom
- Reference point for serial dilutions
- Cover is not airtight
- Size listed two ways
Performance notes
The bead holds the cover slightly off the bottom wall, which limits capillary creep of condensed moisture. The glass is not affected by common lab sterilization methods, wet or dry.
