Flasks

A hand-blown glass flask with interchangeable joints is a laboratory glassware that is made by a skilled glassblower using traditional glassblowing techniques. The glass is shaped by hand and can be customized to fit specific experimental needs.

The interchangeable joints on the hand-blown glass flask allow for easy attachment to other laboratory glassware, such as condensers, thermometers, or other adapters. The joints can be inserted into the flask and then secured using a cork, a plastic clip, or other securing mechanisms.

Hand-blown glass flasks are often preferred over mass-produced glassware due to their higher quality and durability. The glass is thicker, more uniform, and less likely to break due to thermal shock. The hand-blown process also allows for customization of the flask's size, shape, and joint placement to better suit the experimental needs.

These flasks are commonly used in organic chemistry for various types of reactions, such as distillations, refluxing, and solvent extractions. They are available in a range of sizes and shapes, with volumes ranging from a few milliliters to several liters. While more expensive than mass-produced glassware, hand-blown glass flasks are often considered a worthwhile investment for their quality and longevity.
