DURAN 218035457 Erlenmeyer Flask Screw Cap 1000 mL
The DURAN 218035457 is a 1000 mL Erlenmeyer flask equipped with a GL 32 screw neck and a PBT screw cap, engineered for secure liquid handling and storage. Constructed from borosilicate glass 3.3, it provides superior chemical resistance and excellent thermal stability.
The flask includes approximate printed graduations for quick volume estimation and a fired-on white ceramic labelling field that allows durable sample identification. Its screw closure minimizes evaporation and contamination, making it especially suitable for microbiology, chemistry, and pharmaceutical use.
Both the flask and cap are autoclavable (cap resistant up to ~180 °C), ensuring safe sterilization and reusability. With a base diameter of ~131 mm and a height of ~225 mm, it offers a stable design for handling 1 L of liquids.
