Corning Erlenmeyer Flask 1000 ml Polycarbonate Case of 25 Flasks

Corning 1000 ml Polycarbonate Erlenmeyer Flask (431146)

The Corning 431146 is a premium 1000 ml Erlenmeyer flask engineered for high-yield suspension cultures, media preparation, and storage. Manufactured from medical-grade, optically clear polycarbonate, this flask provides the superior mechanical strength and shatter-resistance necessary for high-speed orbital shaking. The flask features a wide-mouth design for easy filling and access, complemented by molded-in graduations for accurate volume measurement. Delivered gamma-sterilized and certified non-pyrogenic, the 431146 is equipped with a leak-proof plug-seal cap, ensuring aseptic integrity and preventing evaporation during long-term incubation. This flask is the industry standard for researchers performing protein expression, scale-up studies, and general laboratory liquid handling.

Technical Performance and Design

• High-Clarity Polycarbonate: Offers glass-like transparency for effortless visual monitoring of cell growth, turbidity, and contamination, with the added safety of a shatter-proof polymer construction.

• Optimized for Shaker Applications: The Erlenmeyer geometry and robust wall thickness are designed to withstand the physical stresses of orbital shaking, providing optimal aeration and mixing for suspension cells.

• Secure Plug-Seal Cap: The high-density polyethylene (HDPE) cap features a deep-skirted plug seal that provides a primary liquid-tight barrier, protecting cultures from external contaminants and preventing leakage.

• Certified Purity: Each flask is sterilized by gamma irradiation to a Sterility Assurance Level (SAL) of 10^-6 and is certified to be non-pyrogenic and non-cytotoxic.
