The Nalgene 4109-0250 250mL Erlenmeyer flask is made of clear polymethylpentene (PMP), has a polypropylene screw cap, and is designed for titration or preparation and storage of cell culture media. The flask is made of PMP, which has a high melting point and good chemical resistance. The cap is polypropylene, which resists most chemicals, has excellent dimensional stability, and can be sterilized. Both the flask and cap can be autoclaved. The polypropylene size 38 cap provides secure storage of samples or culture media. The flask measures 138.4mm high with cap, and the base has an outside diameter of 82.5mm. The inside diameter of the neck is 27.7mm. Molded-in graduated markings indicate approximate volume measurements in 25mL increments. The Erlenmeyer flask is typically used for storing chemicals or samples in a laboratory. Flasks are glass or plastic containers for storing or collecting chemical samples or solutions in scientific laboratories. They come in a variety of sizes and shapes and are designed for a wide range of scientific processes. Erlenmeyer flasks, introduced by German chemist Emil Erlenmeyer in 1861, are shaped like a cone with a wide, flat base that narrows to a neck opening, which can be closed with a stopper or cap.Nalge Nunc International manufactures plastic laboratory containers, outdoor sports bottles, and packaging materials under the Nalgene brand name.
