The Corning 3L spinner flask body is constructed of polystyrene, paddle and shaft from polypropylene and caps from high density polyethylene. All are made of USP Class VI and ISO 10993-18 compliant materials.
Recommended working range of 1L to 3L.
Extended paddle design ensures constant top-to-bottom motion of the liquid without having to adjust the height of the paddle.
Bottom contours on the paddle hug the shape of the flask, eliminating dead spots.
Two wide neck openings for easy pouring; easily accept a 100 mL pipet.
Vertical side baffles break up laminar flow – ensures better mixing and maximizes cell production.
Each system is supplied individually double bagged.
Sterilized by gamma irradiation; have the Highest Sterility Assurance Level (SAL) of 10__ and meets USP XXIV:71 Bacteriostasis, Fungistasis and Sterility Standards.
Single use only. Flasks cannot be autoclaved or resterilized with alcohol. Any attempt to do so will result in degradation of the materials.
Optional Vented Caps (Cat. No 3567) and Aseptic Transfer Caps (Cat. No. 3564) are available.
The Corning disposable spinner flask system comes ready-to-use with a paddle and integrated magnet, reducing the need for time-consuming assembly, cleaning, or reassembly.
Molded from virgin polystyrene and sterile, each spinner flask system assures a clean sterile unit. No more concerns with detergent residues or contamination.
The paddle size and height are optimized for each vessel size. A unique integrated magnet provides smooth, even rotation at required speeds on slow-speed stirrers. Heat build-up in the vessel is reduced by means of a specially designed flange that raises the vessel off the stir-plate surface (125 mL and 500 mL flasks only).
Retrofit kits are available for converting older ProCulture spinner flasks to fit newer dual-bearing impellers.
