Lab Media Storage Amber Bottles 250 mL Pack of 10 - Leakproof GL45

In this review the Lab Media Storage Amber Bottles (250 mL, pack of 10) are evaluated for lab and general-purpose use. The main reason to consider these bottles is the combination of sturdy amber glass with permanent white enamel graduation lines that make measurement and labeling straightforward. The reviewer found the GL45 screw cap and drip-free pouring ring provide a reliable, leakproof seal for storage and transport, while the amber glass reduces UV exposure and withstands common lab conditions.

Key Features

• 250 mL Capacity: Each bottle holds a consistent 250 mL volume and the pack of 10 is useful for batching experiments or inventorying reagents.
• Permanent Graduation Lines: White enamel graduation lines are clear and accurate, making routine measurement and sampling faster and more repeatable.
• Safe Thick Glass: The bottles use thick, sturdy glass with low thermal expansion and good chemical resistance for everyday lab handling.
• GL45 Screw Cap & Leakproof Design: The polypropylene caps form a tight seal and the drip-free pouring ring reduces spills and evaporation during transfers.
• Autoclavable and Reusable: Bottles withstand high-pressure steam sterilization up to 120 C and caps are rated to 140 C, supporting repeated reuse and cleaning.
• UV Protection: Amber glass reduces harmful light exposure, helping preserve light-sensitive solutions and media.

Who It's For

These bottles are best suited for small labs, educational settings, and industrial technicians who need reliable reagent storage, media mixing, or sampling in compact, identical containers. The pack of 10 is especially convenient for organized workflows where multiple labeled containers are required.

They are less appropriate for extremely high-temperature applications above the stated autoclavable limits or for users who need single-use plastic disposables. Users requiring narrow-neck chromatography vials or specialized septum caps should consider other dedicated containers.

Pros & Cons

Pros

• Durable amber glass reduces UV exposure and offers high chemical resistance for corrosive environments.
• Permanent white enamel graduation lines make measurement and labeling simple and reliable.
• GL45 screw cap with drip-free pouring ring provides a tight, leakproof seal and reduces evaporation.
• Autoclavable and reusable design supports sterilization and long-term use.

Cons

• Glass remains fragile compared with plastic; accidental drops can break bottles despite thicker walls.
• Do not tighten caps immediately after autoclaving, which adds a small handling step to avoid vacuum-related breakage.
