Product Description

These rimless conical flasks are specially designed for laboratory culture, mixing, and general sample preparation. The rimless format facilitates the use of cotton plugs, foam stoppers, or custom closures, providing optimal conditions for aseptic techniques in microbiology, plant culture, and molecular biology.

Manufactured from quality glass, the flasks are robust, reusable, and resistant to thermal and chemical stress. Conical shape aids in thorough mixing and minimizes risk of spillage. Available in two convenient sizes (250 mL with narrow neck and 750 mL with wide neck), they are ideal for tissue culture, fermentation, or routine media preparation.
