Glass Erlenmeyer Flasks, Narrow Neck, Graduated conical flasks made from high-quality borosilicate 3.3 glass., Dozen of 12

Details:

This pack of 12 Erlenmeyer flasks, each with a 50mL capacity, features easy-to-read white enamel graduations every 25mL. Made from high-quality, heavy-duty borosilicate 3.3 glass, these flasks offer excellent strength against breakage and can withstand high temperatures and thermal shocks. They are microwavable and autoclavable, with superior chemical durability. The uniform wall thickness is ideal for heating, and the reinforced rim provides protection against high impacts. Conforming to DIN ISO 1773 standards for narrow neck conical flasks, these Erlenmeyer flasks offer superior chemical durability and heat tolerance. Designed for professional laboratories, they are also an ideal choice for science classrooms and household use. Each flask features white enamel graduations every 25mL, a uniform wall thickness ideal for heating, and a reinforced rim to protect against accidental impacts. They meet DIN ISO 1773 standards for conical flasks and are autoclavable, with superior chemical durability. The borosilicate glass has a low temperature gradient and can withstand high temperatures and thermal shocks, with heat tolerances of strain point 515°C, annealing point 565°C, and softening point 820°C.
