Electron Microscopy Sciences Pyrex® Petri Dish 150x20 Mm

Electron Microscopy Sciences These flat, clear dishes will withstand repeated sterilization (wet or dry). The edges are beaded to provide greater mechanical strength. The bead also provides a means to equally space the sidewalls of the bottom and cover, thereby reducing the capillary action of condensed moisture on the slides. They are not effected chemically or thermally by methods commonly employed in laboratories including sterilization. The covered dish is not airtight. The tops are marked in blue enamel and the bottoms are marked in white enamel to make sorting easier. Bottoms also have a triangular, enamel reference point for serial dilutions. - EMS
