DURAN 218033653 Erlenmeyer Flask with Screw Cap 250 mL
The DURAN 218033653 is a 250 mL Erlenmeyer flask with GL 32 screw neck and PBT screw cap, made from borosilicate glass 3.3 for high chemical and thermal resistance. It features approximate graduations for quick volume estimation, a fired-on white labelling field, and a retrace code for quality traceability. The screw cap ensures secure closure, reduces contamination risk, and both flask and cap are fully autoclavable (cap resistant up to ~180 °C). Compact in size (~85 mm diameter × 149 mm height), it is ideal for reagent preparation, microbial culture, and safe storage of solutions.
