Product Description
Product Description
This 50mL Erlenmeyer flask is made from borosilicate 3.3 glass with a narrow neck and conical shape that reduces splashing during mixing. White enamel graduations are marked every 25mL. The flask features uniform wall thickness for even heating and a reinforced rim for impact protection.
Conforms to DIN ISO 1773 standards for narrow-neck conical flasks. The narrow neck allows the use of stoppers and reduces evaporation losses during heating.
Borosilicate 3.3 glass is autoclavable and chemically durable. Heat tolerances: strain point 515°C, annealing point 565°C, softening point 820°C.
