Corning Media Storage Bottle 500 ml Polystyrene Plug Cap 24 Bottles

Corning Easy-Grip Disposable Media Storage Bottle – 500 mL, Clear Polystyrene, 45 mm High-Density Polyethylene Plug Seal Cap, Sterile (MPN: 430282)

The Corning 430282 is a premium, laboratory-grade disposable plastic storage bottle precision-engineered for holding tissue culture media, biological buffers, and other aqueous laboratory solutions. Molded from crystal-clear virgin polystyrene (PS), this 500 mL cylindrical bottle features an ergonomic, low-profile design with specialized fluted easy-grip sides to facilitate safe, slip-free handling in biosafety hoods. Each bottle comes complete with a prominent 45 mm wide-mouth neck and a matching orange high-density polyethylene (HDPE) plug seal cap that compresses perfectly to form a hermetic, leak-proof barrier. Arriving fully radiation-sterilized and certified non-pyrogenic, this storage vessel is highly optimized for direct sample collection or serving as a replacement receiver bottle for vacuum bottle-top filtration units.

Technical Performance and Design

• Ergonomic Easy-Grip Sidewall Channels: Designed with indented exterior grip channels that improve mechanical hold, significantly lowering the risk of accidental drops or spills when handling fluid volumes with wet nitrile gloves.

• Crystal-Clear Polystyrene Body: Fabricated from premium, optically transparent virgin polystyrene resin, allowing for effortless visual inspection of fluid clarity, color changes, and particle sediment tracking at a glance.

• Hermetic 45 mm Plug Seal Cap: Outfitted with a heavy-duty, threaded orange HDPE cap featuring an integrated internal plug seal profile. This configuration establishes an airtight, contamination-free physical seal that prevents volatile evaporation and liquid leakage.

• High-Contrast Molded Volumetric Scales: Features permanent, clear molded-in graduation lines at 25 mL increments running up the container wall, supporting rapid, reliable liquid alignment and exact remaining volume checks.

Key Benefits and Applications

• Sterile Media and Buffer Archiving: The standard container choice for mixing, aliquoting, and banking sterile cell culture media, serum feed stocks, molecular biology buffers, and enzymatic master broths.

• Vacuum Filtration Receiver Vessel: Threaded neck spacing allows this container to connect directly underneath standard 45 mm bottle-top filtration funnel units, functioning as a sturdy clean collection reservoir.

• Cross-Contamination Avoidance: The single-use disposable layout entirely clears the facility of tedious glass washing routines, autoclaving loops, and validation cleaning runs required by legacy heavy glass media bottles.

• Temperature Stability Bounds: Retains high structural stability and seal hold across standard processing scales, supporting applications from frozen storage at minus 20 C up to brief handling thresholds at plus 70 C.
