The 125mL Nalgene 4115-0125 plain-bottom Erlenmeyer flask is made of clear glycol-modified polyethylene terephthalate (PETG), has a high-density polyethylene (HDPE) vented cap with a hydrophobic 0.2µm polytetrafluoroethylene (PTFE) membrane that allows sterile air exchange, and is ideal for shaker and suspension cell culture, media preparation, or storage. Clear PETG reduces the chance of cross-contamination and provides visibility of stored samples. Packaged individually, the flask provides a five-year shelf life and a 1E-6 sterility assurance level (SAL). The flask is disposable, non-pyrogenic, and non-cytotoxic. The flask measures 113mm high with cap, and the widest point of the base has an outside diameter of 66.3mm. The inside diameter of the neck is 26.4mm. Molded-in graduated markings indicate the approximate volume. 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. The company was founded in 1995, and is headquartered in Rochester, NY.
