Corning 430641U U-Shaped Canted Neck Cell Culture Flask 75cm²

Description

Product Overview

Corning’s 430641U U shaped canted neck cell culture flask is engineered from high quality borosilicate glass that resists thermal shock and chemical corrosion, providing a durable vessel for demanding laboratory protocols. The flask offers a 75cm2 growth area with a smooth low adhesion interior that minimizes cell loss during harvesting. Its unique canted neck design reduces the number of sharp corners, allowing easier access to the vent cap and simplifying the scraping process for adherent cell lines. The vented cap maintains a stable gas exchange environment while protecting the culture from contamination, and the flask is supplied sterile, ready for immediate use.

Dimensions of the flask are optimized for standard incubator shelves, measuring 19.25 inches in length, 15.79 inches in width, and 14.37 inches in height, with a total weight of 2.2 pounds per unit. The compact footprint enables storage of a large number of flasks in limited space, supporting high throughput experiments. The model number 1196M78CS identifies this specific configuration, and the product is listed under ASIN B01JCYT88E for easy reference in online catalogs. With a best sellers rank of #3 in Lab Cell Culture Flasks, the design has been validated by a broad user base across academic and industrial research settings.

The flask’s vented cap incorporates a silicone gasket that seals securely while allowing continuous diffusion of oxygen and carbon dioxide, essential for maintaining optimal pH levels in cell culture media. The cap also features a convenient pipet divot, enabling optional removal of liquid without disturbing the cell monolayer. This combination of features supports reproducible results across multiple passages and reduces the risk of cross contamination. The product is packaged in a bulk case of 100 units, providing a cost effective solution for laboratories that require consistent supplies for routine cell culture workflows.

Corning’s reputation for quality control is reflected in the rigorous testing each flask undergoes, including sterility assurance, dimensional verification, and glass integrity checks. The manufacturing process adheres to ISO 9001 standards, ensuring that each flask meets predefined performance criteria. Users benefit from the predictable behavior of the glass surface, which supports a wide range of cell types, from fragile primary cultures to robust immortalized lines. The transparent construction allows clear visual monitoring of cell confluence and morphology without the need to remove the flask from the incubator.

Overall, the 430641U flask combines thoughtful ergonomic design with reliable material properties, delivering a versatile tool for cell culture, vaccine development, toxicology testing, and biomanufacturing research. Its compatibility with standard laboratory equipment such as orbital shakers, centrifuges, and automated handling systems further enhances its utility in both manual and high throughput environments.

All flasks comply with ASTM standards for laboratory glassware and are manufactured under GMP-like conditions, ensuring that they meet the stringent requirements of pharmaceutical and biotech industries. The product is also compatible with ISO-classified cleanroom environments, allowing its use in regulated processes such as cell-based therapeutic manufacturing.

Usage

The flask is ideally suited for routine maintenance of adherent cell lines, where the canted neck facilitates gentle scraping and detachment of cells for passaging or downstream assays. Researchers can perform media changes, cell harvesting, and drug treatment directly within the flask, minimizing handling steps and preserving cell viability. The vented cap ensures that cultures remain aerated throughout the experiment, reducing the likelihood of hypoxic stress.

In addition to standard tissue culture, the flask can be employed in specialized applications such as three-dimensional spheroid formation, where the smooth interior promotes uniform aggregation of cells. The large growth surface accommodates high cell densities, making it appropriate for scale-up studies and production of biologics. The sterile packaging eliminates the need for additional autoclaving, saving time and reducing the risk of introducing contaminants.

The design also supports integration with automated liquid handling platforms, as the easy-grip neck provides a stable point for robotic arms to manipulate the flask. This feature is valuable for laboratories implementing high-throughput screening protocols that require consistent positioning and rapid exchange of culture vessels. The clear glass allows imaging systems to capture real-time data on cell morphology and confluence without disturbing the culture.

For educational settings, the flask offers a safe and transparent vessel for teaching cell culture techniques, allowing students to observe cell growth and learn aseptic practices. Its robust construction tolerates frequent handling, making it a durable choice for teaching labs that experience high turnover of equipment. The inclusion of a vented cap also teaches the importance of gas exchange in maintaining healthy cell cultures.

Researchers performing drug screening can take advantage of the flask’s large surface area to conduct dose-response assays directly in the vessel, reducing the need for transfer steps. The vented cap maintains consistent pH across wells, and the transparent glass enables real-time optical density measurements using plate readers adapted for flask formats.
