Pyrex Borosilicate Glass Petri Dish Cover - 150mm Diameter x 15mm Height - Lab-Grade (Pack of 12) - Ideal for Scientific Experiments, Microbiology Research & Laboratory Use

These flat clear PYREX dish covers will withstand repeated sterilization (wet or dry). Approximate dish cover diameter and height is 150 x 15mm. 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 covers are marked in blue enamel. Bottom not included. Material: borosilicate glass code 7740. Dish style: Petri. Petri dish style: 150 x 15mm. Top style: beaded rim. Feature: reusable. Diameter: 150mm. Height: 15mm. Corning #: 3160-150CO.
