Superior Thermal Shock Resistance: Made from high-grade Borosilicate 3.3 glass, this flask can withstand extreme temperature changes. It is safe for use on hot plates, open flames (with appropriate mesh), and in autoclaves, as well as in freezers and refrigerators.
-
Convenient Wide Mouth Design: The enlarged opening allows for easy addition of solid reagents, stir bars, and liquids. It also makes cleaning with brushes significantly faster and more effective, reducing the risk of breakage compared to narrow-neck flasks.
-
Exceptional Chemical Durability: The inert glass surface resists attack from most acids, bases, and solvents, ensuring your samples remain pure and uncontaminated.
-
Excellent Sealing Performance: The soft, flexible silicone stopper creates a tight, airtight seal that helps prevent leaks, evaporation, and contamination. Ideal for fermentation, chemical storage, and lab experiments.
-
Removable Center for Thermometer: The center plug can be easily removed to insert a thermometer, allowing you to monitor temperature without opening the container. Reinsert the center plug when not in use to maintain a secure seal.
-
Acid & Alkali Resistant: Withstands exposure to most acids, bases, and common laboratory chemicals, ensuring long-lasting performance and sample safety.
