Glass Erlenmeyer Flasks, Narrow Neck, Graduated conical flasks made from high-quality borosilicate 3.3 glass., Pack of 6

Details

Here is the corrected text: This pack of six 500mL Erlenmeyer flasks features narrow necks and is made of heavy-duty borosilicate 3.3 glass. Each flask has a 500mL capacity, easy-to-read white enamel graduations every 100mL, uniform wall thickness ideal for heating, and a reinforced rim to protect against accidental impacts. Made to meet DIN ISO 1773 standards for conical flasks, these flasks are autoclavable, microwavable, and offer superior chemical durability. They can withstand high temperatures and thermal shocks, with a low temperature gradient. The borosilicate glass has the following heat tolerances: strain point 515°C, annealing point 565°C, and softening point 820°C. These flasks are designed for use in professional laboratories but are also an ideal choice for science classrooms and household use.
