Wheaton* Media Lab Bottles, Graduated and Ungraduated
Large openings, no-drip pour lip and sloping shoulders to facilitate pouring and cleaning. Graduated bottles show approximate volume graduations, and have a large writing area. Bottles meet USP Type I standards. Low alkali content helps to prevent changes in pH and maintain purity of contents. Rubber-lined caps are widely used for the mixing and storing of culture media. Teflon*-lined caps feature liners which are inert to most chemicals. Autoclavable.
