Corning® 250 mL Square PET Storage Bottles with 45 mm Caps

Product Number 431531

New square polyethylene terephthalate (PET) storage bottles are easier to handle, require less space (13-20%) on the shelf and are ideal for mixing, sampling and storage. PET resin is lightweight, break-resistant and transparent as glass. Bottles use a linerless, one-piece autoclavable orange GL45 threaded polypropylene plug seal cap.


  • Good for storage of media, buffers and other aqueous solutions
  • Large 37mm opening provides easier access for liquid transfer
  • Screened white enamel graduations are easier to read than molded graduations
  • Sterilized to SAL 10⁻⁶
  • Large white marking spot for easier identification and easy opening linear tear packaging
  • Individually packaged bottles are sterilized by gamma radiation and are nonpyrogenic
