Shake flasks are essential laboratory tools used in microbiology, cell culture, and biochemical research. These flasks feature a conical shape with a flat base and a narrow neck, designed to facilitate efficient mixing and aeration of liquid cultures when placed on an orbital shaker. Common applications include microbial fermentation, suspension cell growth, and media preparation. Typical products in this category may include Erlenmeyer flasks (glass or plastic), baffled flasks for enhanced oxygen transfer, vented cap flasks for gas exchange, and sterile disposable flasks. Key features often include graduated markings, autoclavable materials (borosilicate glass or polycarbonate), and various capacity options ranging from 50ml to 5L. Specialty variants may incorporate features like integrated sensors or stackable designs for high-throughput workflows.
