250ml Narrow Neck Amber Borosilicate Glass Conical Laboratory Flask
Designed for light sensitive solutions, the Eisco Labglass 250 ml Amber Conical Flask offers protection and durability for everyday laboratory preparation.
Made from amber borosilicate glass 3.3, this narrow-neck Erlenmeyer flask reduces light penetration to safeguard delicate samples. It withstands thermal stress, repeated heating and contact with common reagents, ensuring reliable long-term use. The conical body supports controlled mixing with less splashing, while the reinforced rim increases resilience under repeated handling. Graduated markings provide approximate volumes, and the flask is autoclavable at 121 ยฐC for safe reuse.
