<h2>What Are Glass Media Bottles?</h2>
 Glass media bottles are borosilicate screw-cap storage vessels designed for preparing, autoclaving, and dispensing laboratory culture media, biological buffers, and liquid reagents. Unlike Erlenmeyer flasks with foam closures, media bottles have threaded screw caps providing a leak-proof seal for transport, dispensing, and long-term storage. Globe Scientific glass media bottles at MBP are manufactured from borosilicate glass (ASTM E438 Type I / USP Type I), supplied with polypropylene (PP) screw caps, and are autoclavable at 121&deg;C. Choose clear borosilicate for most reagents; choose amber glass for light-sensitive compounds such as photodegradable stains, bilirubin standards, certain vitamin solutions, and riboflavin.

<h2>How to Choose Glass Media Bottles</h2>
 Clear vs. Amber Glass Clear borosilicate media bottles are appropriate for reagents that are not UV- or visible-light-sensitive. Amber glass bottles filter light below approximately 450nm, protecting light-degradable contents from photodegradation. Common applications for amber storage include: ethidium bromide solutions, crystal violet stain, bilirubin calibrators, vitamin B2 (riboflavin) solutions, and other photosensitive reagents. Choose amber glass when the reagent specification or manufacturer's instructions recommend light protection. Wide-Mouth vs. Standard Neck Standard-neck media bottles are suited for liquid-to-liquid transfers and dispensing. Wide-mouth media bottles allow easier filling with solid powder media (agar, broth powder, salt), scooping viscous materials, and thorough cleaning &mdash; preferred for culture media preparation where media powder is dissolved directly in the bottle. Graduated vs. Non-Graduated Graduated media bottles have approximate volume markings for guidance during media preparation without a separate measuring cylinder. Markings are typically &plusmn;5% and are not certified for precision volumetric work. Cap and Pouring Ring PP screw caps are autoclavable at 121&deg;C. Loosen caps one quarter-turn before autoclaving to allow steam pressure equalisation. Some formats include a pouring ring insert on the neck interior that prevents liquid from running down the outside of the bottle when dispensing.

<h2>Specifications Context</h2>
 Globe Scientific glass media bottles are manufactured from borosilicate glass conforming to ASTM E438 Type I and USP Type I, providing chemical resistance to acids, bases, alcohols, and most organic solvents. PP screw caps are autoclavable at 121&deg;C; verify PP compatibility with any strong oxidising acid or halogenated solvent before use. Amber glass attenuates light below ~450nm, protecting photosensitive contents during storage. MBP stocks clear and amber glass media bottles from Globe Scientific for labs in the US, Canada, and worldwide.

Replacement Gl-45 Drip Ring, 1 Each

United Scientific® Replacement Gl-45 Drip Ring by United Scientific is a blue pouring/drip ring that replaces the original ring on GL45 media bottles. It works with all GL45 media bottles and gives a cleaner pour with fewer drips down the bottle. Labs that wash and reuse glass media bottles keep spares on hand when rings are lost or worn.
