Corning Pyrex Borosilicate Glass Petri Dish Bottom Only, 55mm Diameter x 17mm Height (Pack of 12) - 3160-60BO

These flat clear PYREX dish bottoms will withstand repeated sterilization (wet or dry). Approximate dish bottom diameter and height is 55 x 17mm. The edges are beaded to provide greater mechanical strength. The bead also provides a means to equally space the side walls of the bottom and cover - thereby reducing the capillary action of the condensed moisture on the sides. They are not affected chemically or thermally by any of the methods commonly employed in laboratories where sterilization is routinely used. The bottoms are marked in white enamel to make sorting easier. Bottoms also have a triangular enamel reference point for serial dilutions. Cover not included. Material: borosilicate glass code 7740. Dish style: Petri. Petri dish style: 60 x 15mm. Top style: beaded rim. Surface treatment: not treated. Feature: reusable. Diameter: 55mm. Height: 17mm. Corning #: 3160-60BO.
