Details

Here is the corrected text: This pack of 12 Erlenmeyer flasks, each with a 25mL capacity, features easy-to-read white enamel graduations every 12.5mL. Made from high-quality, heavy-duty borosilicate 3.3 glass, these flasks offer excellent strength against breakage and are microwavable and autoclavable, with superior chemical durability. They can withstand high temperatures and thermal shocks due to their uniform wall thickness, ideal for heating, and reinforced rim, which protects against high impacts. Conforming to DIN ISO 1773 standards for narrow-neck conical flasks, these Erlenmeyer flasks offer superior chemical durability and heat tolerance, making them an excellent choice for professional laboratories, science classrooms, and household use. The borosilicate glass used in these flasks has the following heat tolerances: strain point 515°C, annealing point 565°C, and softening point 820°C.
