Emil Richard Erlenmeyer

Biography & contributions

Emil Richard Erlenmeyer [Emil Erlenmeyer], a German Chemist was born on June 28, 1825 – died on January 22, 1909. Erlenmeyer was best known for his contributions like the invention of Erlenmeyer flask, and formulation of Erlenmeyer rule.

Erlenmeyer’s other important works include conducted hydrolysis of ether to alcohol reaction, synthesized aminohexoic acid in the year of 1859, discovered the nature of glycides in the year of 1860, isolated glycolic acid from unripe grapes in the year of 1864, synthesized sodium oxalate by heating sodium formate in the year of 1868, synthesized phenyl-lactic acid in the year of 1880, prepared pyruvic acid by the distillation of tartaric acid in the year of 1881.

In 1882 he synthesized tyrosine an aromatic amino acid from phenylalanine and also worked on isomerism of the cinnamic acids.

Erlenmeyer Flask

Erlenmeyer flasks named after the German chemist Emil Erlenmeyer, which are normally used to measure, mix, and store liquids in different laboratories. Erlenmeyer flask is also known as a conical or E-Spot flask. An Erlenmeyer flask features a flat, conical body, and a cylindrical neck.

The most common sizes of erlenmeyer flasks are 250 ml and 500 ml. Erlenmeyer flasks can be found in different capacities of 50, 125, 250, 500, 1000 ml. Erlenmeyers are used in chemistry labs for titration, testing pH of liquids and also used to heat liquids.

Erlenmeyers are also used other than chemistry laboratories, such as microbiology labs for the preparation of microbial cultures. Plastic Erlenmeyer flasks used in cell culture are pre-sterilized and feature closures and vented closures to enhance gas exchange during incubation and shaking.

Facts about pyruvic acid

Pyruvic acid is an intermediate metabolite product. Pyruvic acid can be made from glucose through glycolysis, converted back to carbohydrates via gluconeogenesis, or to fatty acids through acetyl-CoA. It can also be used to construct the amino acid alanine and be converted into ethanol.

Pyruvic acid supplies energy to living cells through the citric acid cycle/ Krebs cycle in aerobic respiration condition and alternatively ferments to produce lactic acid when oxygen is lacking.
