What are Erlenmeyer flasks?
flasks are a type of pure glass or plastic laboratory equipment used to measure, mix or hold fluids or chemicals. Laboratory flasks are available in a number of shapes, sizes and with different number of holes, as determined by their intended use. Together with the test tubes, Erlenmeyer flasks - also known as et or conical flasks - are among the most famous pieces of laboratory glass recognized by the general public. Named after their inventors, Erlenmeyer flasks are clean conical flasks ending with long narrow necks, which include a small, comfortable lip discharge at the top of the glass. The design of these flasks has proved to be particularly useful in the laboratory environment for many reasons, including safety and fulfillment of various experimental needs.
Erlenmeyer flasks are often marked with white dashes of volume measurements -TJ. Large round flask bottom allows a container of firmSitting on a laboratory table safely without a chemist slightly crashing or shock. The long column necks of Erlenmeyer's flasks serve several purposes. They provide an easy area for moving or transporting flasks with hands or pliers, if necessary and allow the flasks to be easily secured by metal clamps, for example, through a heat source. In these blood vessels, liquids are easily mixed - they swirled together by turning the bottom of the flask - without a significant risk of cleft.
Although it can be stopped by rubber peaks, long necks Erlenmeyer flasks also reduce the loss of fluid by evaporation. This advantage is particularly useful in maintaining the right concentrations when a chemist works with volatile fluids. The column necks also allow heating the titration or distillation fluidinerlenmeyer flasks, without the usual risk of excessive liquid cooking, to the connected distillation coils or tubes connected to the upper part of the flask.
Most Erlenmeyer flasks are made of glass, although they areSome plastic containers are available. Although they are broken, glass flasks are more useful in commercial laboratory. Glass flasks can be heated without the risk of contaminating the contained substance with volatile substances potentially relaxed plastic flask. Sterilization glass flask with heat is also easier than disinfectant and cleaning plastic flasks. Erlenmeyer flasks are available in a wide range of sizes, although they are most often available in sizes 250 and 500 ml (CC).
