It can also be used as a convex cover for beakers and Erlenmeyer flasks to limit airborne contaminants, while still allowing gas exchange. All sizes are molded to the same contour for easy stacking. Shatter-proof PTFE material is chemical resistant and easy to clean. - Inert 13chemically resistant - Smooth and unbreakable - Use as beaker covers 2 Saint Gobain Diam. PK Cat.

The flat bottom provides good surface contact with a heat source, while the non-stick angled walls direct fluids to the base, which limits condensation on the dish wall. This PFA dish can be used in a wide range of temperatures, from cryogenics to 260 °C. The dish is also ideal for holding solid samples or small volumes of liquid. Features a broad spout for easy pouring. - Chemically inert - Ideal for trace metal analysis - Transparent for easy viewing - Perfect for microwave use - Smooth, non-stick surface 3 Saint Gobain Capacity Height PK Cat.

The evaporating dish can also be used as a shallow bath, as a drying dish or as a beaker cover to protect contents from dust and other contaminants. PTFE material is unbreakable, chemically inert, and withstands temperatures up to 288 °C. The non-stick surface is stain resistant and easy to clean. Features a broad spout for easy pouring. - Chemically inert - Ideal for ultra-pure samples - Withstands temperatures up to 288 °C 4 Saint Gobain Capacity Height PK Cat.

Due to a conical depression in the middle of the base very small amounts of a solvent are adequate to absorb the evaporated samples. 5 Capacity Diam. Height PK Cat.
