Empowering the Future of Science Education

United Scientific® GL 80 Wide Mouth Square Media & Storage Bottles are designed for safe storage, preparation, and transfer of laboratory liquids and media. The square profile maximizes storage efficiency, while the wide mouth opening allows easy filling, pouring, and cleaning—ideal for busy academic, research, and industrial laboratories.

Constructed from durable borosilicate glass, each bottle offers excellent chemical resistance and thermal stability. Bottles are fully autoclavable and feature clearly imprinted graduations for accurate volume reference. Each bottle includes a GL 80 polypropylene screw cap, autoclavable up to 140 °C.

For safe autoclaving, caps should be placed loosely on the bottle; tightening immediately after sterilization may create a vacuum during cooling and risk glass breakage. Available in multiple capacities and pack sizes, these bottles support flexible laboratory workflows while maintaining consistent performance and reliability.
