Corning Pyrex Bottle 500 ml with GL45 Cap Total of 16 Bottles

Corning PYREX 1399-500 Slim Line Media Storage Bottle – 500 mL, Borosilicate Glass, GL45 Cap

The Corning 1399-500 is a premium 500 mL reusable Slim Line media storage bottle designed for mixing, sampling, and storing culture media, biological buffers, and aggressive aqueous solutions. Fabricated from Type 1 Class A (ASTM E-438) PYREX® borosilicate glass, it features exceptional chemical durability and resistance to thermal shock. Unlike traditional cylindrical storage bottles, this specialized Slim Line model incorporates molded, indented gripping zones along the sides for safer, slip-free handling. It also features a narrower overall diameter to optimize shelf and autoclave real estate, complete with a modified orange polypropylene GL45 screw cap requiring 1/3 fewer turns to secure a tight seal.

Technical Performance and Design

• Indented Gripping Zones: Ergonomically molded contours along the side walls provide a safe, secure handhold when pouring or handling liquids, heavily reducing the risk of accidental drops—even when handling the glass with slick, damp laboratory gloves.

• Space-Saving Narrow Diameter: The slender structural footprint utilizes significantly less space on crowded benchtops, cold room shelving, refrigerators, and inside autoclave chambers compared to traditional wide-body 500 mL media bottles.

• Quick-Turn GL45 Cap Layout: The orange polypropylene screw cap is engineered with wider knurls for an easy twist grip and a quick-thread finish that seals completely with 1/3 less rotation than a legacy GL45 cap, accelerating high-volume sample compounding shifts.

• Heavy-Duty Borosilicate Matrix: Built from premium low-expansion glass that tolerates rapid temperature shifts. It includes a built-in, linerless plug-seal mechanism inside the cap alongside a drip-free pouring ring to guarantee clean, zero-waste decanting.

Key Benefits & Applications

• Media and Buffer Preparation: The ideal laboratory vessel for mixing, heating, sterilizing, and holding sensitive cell culture media, liquid reagents, and chemical master batches.

• Aggressive Solvents & Acids: The inert borosilicate structure resists corrosion or leaching from chemical compounds, preserving the exact purity lines of HPLC mobile phases or stock concentrates.

• Autoclaving Efficiency: The combined profile of narrow physical dimensions and high heat tolerance enables laboratories to autoclave maximizing bottle density per chamber running block.

• Drip-Free Fluid Pouring: The integrated, matching plastic pouring ring completely eliminates external run-off tracking along the outer glass walls, keeping work benches dry and chemical stains contained.
