Create a safe work environment with Wheaton Safety Coated Jars. If a jar is accidentally broken, the PVC based plastisol coating on the outside of jar retains the contents long enough for proper disposal. Ideal for lab or field applications, the jar's non-slip coating allows for greater ease and stability when handling wet or dry. The wide mouth style is ideal when used for powders and viscous samples. Manufactured from soda lime glass that conforms to USP Type III requirements.
