Pyrex Corning 1395-500 500ml Round Media Storage Bottle - Pack of 2

In this review the Pyrex Corning 1395-500 500ml round media storage bottle is assessed for lab users who need dependable glass containers for cell culture media and reagent storage. The bottom line: this two-pack of 500ml bottles with GL45 screw caps is best for labs that prioritize chemical resistance and thermal stability in reusable glassware. The review focuses on build quality, handling, and everyday usability so researchers and lab managers can decide if these bottles fit routine sterilization and storage workflows.

Key Features

• 500ml capacity: Provides a practical volume for preparing, storing and dispensing moderate batches of media without frequent refills.
• Round bottle form: The round shape makes handling and pouring straightforward while fitting commonly used clamps and holders.
• Pyrex glass construction: Offers high chemical resistance and thermal stability useful for autoclaving and repeated lab use.
• GL45 screw cap: Standardized neck thread simplifies sealing, capping and compatibility with many accessory closures.
• Pack of 2: Buying two bottles together gives immediate redundancy for parallel preparations or spare capacity.

Who It's For

The Pyrex Corning 500ml bottles are aimed at academic and industrial labs, cell culture facilities, and technicians who need reliable glass storage that tolerates sterilization. They suit users who prefer reusable glass over plastic for solvent compatibility and long-term durability.

These bottles are less suited to fieldwork where breakage risk is high or workflows that demand single-use disposables for contamination control. Labs requiring specialized fittings beyond a GL45 cap should verify accessory compatibility before purchase.
