The conical design, featuring a wide base and narrow neck, promotes efficient mixing, swirling, and pouring while minimizing the risk of spillage. Graduated markings in white provide precise volume measurements, and the robust PTFE‑lined polypropylene screw cap creates an airtight seal that is both acid‑proof and autoclavable, extending the flask’s lifespan and simplifying sterilization procedures. Dimensions include a base diameter of 3.4 inches, an overall height of 6.1 inches, and an inner neck diameter of 35 mm, offering ample capacity for a variety of experimental needs. The flask weighs approximately 11.2 ounces, making it easy to handle yet sturdy enough for repeated use. Designed with both professional and hobbyist users in mind, this flask balances performance, safety, and convenience, delivering a reliable tool for any setting where liquid handling is essential.

Usage

In a modern research laboratory, the EISCO Erlenmeyer Flask serves as a versatile vessel for tasks ranging from simple solution preparation to complex titration and reflux operations. Its chemical‑resistant borosilicate composition allows it to withstand aggressive acids, bases, and solvents without compromising structural integrity, making it suitable for organic synthesis, analytical chemistry, and microbiology protocols. The PTFE‑lined cap ensures a secure closure during heating, cooling, or storage, preventing evaporation and contamination. Because the flask is autoclavable, it can be sterilized at high temperatures, which is essential for microbiological cultures, cell culture media preparation, and any application requiring aseptic conditions. Additionally, the dishwasher‑safe design reduces the time and effort needed for routine cleaning after experiments. Beyond the laboratory, the flask’s elegant conical shape and clear graduations make it an attractive choice for educational demonstrations, home chemistry kits, and even artistic projects such as crafting decorative potions or custom lighting fixtures. Its durability and ease of maintenance mean that it can be used repeatedly in classroom settings, hobby workshops, or small‑scale production environments without the need for frequent replacement.
