Corning Easy Grip Storage Bottle 1 L Polystyrene Plug Seal Cap Case of 24 Bottles

Corning® 1 L Easy Grip Polystyrene (PS) Sterile Storage Bottles, Plug Seal Caps (430518) – Case of 24

The Corning® 430518 is a premium, sterile laboratory fluid management vessel engineered for the storage, staging, and transport of tissue culture media, fetal bovine serum (FBS), sensitive biological reagents, and analytical buffers. Precision-molded from crystal-clear, high-purity virgin polystyrene, this 1 Liter bottle incorporates an Easy Grip structural profile along the upper body circumference to facilitate secure hand manipulation under biosafety hoods. The system integrates an orange, high-density polyethylene plug seal screw cap that forms a gas- and liquid-tight mechanical compression seal, completely suppressing evaporation-driven pH shifts or biological weeping. Arriving as a commercial case of 24 individually wrapped bottles, this single-use configuration is standard hardware for upstream bioprocessing, master mix aliquoting, and aseptic sterile fluid archiving.

Technical Performance & Structural Architecture

• Ergonomic Easy Grip Side indents: Features deep, molded-in recessed finger channels around the upper shoulder matrix. This mechanical grip architecture minimizes slip risks when handling the container with wet or alcohol-sprayed nitrile gloves, reducing the hazard of costly reagent spills.
• Deep-Molded Plug Seal Cap Geometry: Outfitted with an orange, high-density polyethylene (HDPE) screw closure incorporating a dynamic interior plug seal. This plug extends directly down into the bottleneck orifice, maintaining a reliable dual-surface compression boundary that protects contents from ambient atmospheric exposure during cold room storage.
• Permanent High-Contrast Volumetric Scale: Molded with highly legible, permanent graduations running along the clear face of the bottle in 50 mL increments. This provides long-term volume verification that will not blur or degrade when wiped down with 70% isopropyl alcohol or specialized cleanroom disinfectants.
• Aseptic Individual Peel-Pack Protection: Every storage bottle arrives pre-sterilized via validated gamma irradiation and is individually sealed inside an easy-to-peel medical-grade polymer bag. This ensures that each unit remains completely sterile and dust-free until the moment of use inside a laminar flow bench.

• Molecular Biology Master Mix Compounding: Provides an inert, clear, low-extractable plastic vessel for staging high-volume salt gradients, molecular buffers, and HPLC water storage without introducing trace chemical plasticizers.
• Aseptic Harvest Pooling: Serves as an ideal, non-cytotoxic collection basin for pooling sterile supernatants or filtrates discharged from large-capacity concentration devices like **Corning 500 mL Centrifuge Tubes (SKU 431123)**.
• **cGMP Cleanroom Lot Serialization:** Every individual product package is marked with a dedicated manufacturing lot code, ensuring complete, audit-ready batch traceability across commercial pharmaceutical and vaccine production lines.

Corning® is a registered commercial trademark of Corning, Inc. Catalog number 430518 specifies the 1 L polystyrene storage bottle with an orange plug seal cap. For applications requiring direct thermal sterilization via standard pressure steam autoclaving, alternative polymer chemistries such as Polycarbonate (PC) or Polyethylene Terephthalate Glycol (PETG) must be substituted, as polystyrene will undergo structural deformation at standard $121^\circ\text{C}$ parameters.
