DURAN 241202707 Evaporating Flask Pear Shaped 100 mL

DURAN 241202707 Evaporating Flask Pear Shaped 100 mL  Joint NS 29/32

The DURAN 241202707 is a 100 mL pear-shaped evaporating flask made from premium DURAN® borosilicate glass 3.3, engineered for use in solvent evaporation, concentration, and rotary evaporator applications. Its pear-shaped geometry provides a broad base and narrow neck, increasing surface area to promote efficient evaporation while maintaining durability under repeated heating and cooling cycles.

The flask is fitted with a precision NS 29/32 ground-glass joint, ensuring secure and leak-proof connections to condensers, adapters, or other glass apparatus. Manufactured by DWK Life Sciences, it offers high chemical resistance, low thermal expansion, and is fully autoclavable for safe sterilization.
