When was the Erlenmeyer flask invented?
But for some strange reason, the Erlenmeyer Flask, a flat bottom flask invented by German chemist Emil Erlenmeyer in 1861 has stayed with us far longer than it should have.
Who invented Erlenmeyer flask?
B, An Erlenmeyer flask. These inverted conical flasks were invented in 1861 by the German chemist Emil Richard August Carl Erlenmeyer (1825–1909) and have been used ubiquitously in laboratories throughout the world. Dr. Erlenmeyer was the first chemist to synthesize tyrosine, guanidine, creatine, and creatinine (3 ).
Why was the Erlenmeyer flask invented?
Named after the German chemist Emil Erlenmeyer (1825–1909), who created it in 1860. The flask aids in stirring and or heating solutions and is purposefully designed to be useful for those tasks.
What is the purpose of an Erlenmeyer flask?
Erlenmeyer or titration flasks have wide flat bottoms, conical bodies, and tall cylindrical necks. They are named after their inventor Emil Erlenmeyer. Erlenmeyer flasks are used to contain liquids and for mixing, heating, cooling, incubation, filtration, storage, and other liquid-handling processes.
What was Erlenmeyer’s full name?
The Erlenmeyer flask is named for Emil Erlenmeyer (1825–1909), a German organic chemist who designed the flask in 1861. The flask is often used for stirring or heating solutions and is purposefully designed to be useful for those tasks.
Can you heat an Erlenmeyer flask?
So, although Erlenmeyer flasks can be heated, they are not specifically designed for high temperature, constant heating applications. For this, you should use a boiling flask. This because his conical shape does not allow an uniform expansion and so the glass could break.
Why is a flask shaped the way it is?
The reason for this curve is simple: so that it can easily be pressed against one’s body so that it is better concealed. A curved flask fits better in a front or back pocket as it will press against one’s leg or thigh. Even a flask that is kept in someone’s boot or sock can be pressed against the leg well.
Can you boil in a beaker?
Water in a beaker cannot be made to boil by placing it in a bath of boiling water.
What is an Erlenmeyer flask and how is it used?
An Erlenmeyer flask or conical flask is a kind of flask with a base in the shape of a cone and a short neck. It was first invented in 1861 by a German chemist named Richard Erlenmeyer . Erlenmeyer Flasks are used in laboratories. This type of flask is used as a container for chemical substances, or to heat or boil liquids.
Why are Erlenmeyer flasks the shape they are?
Its tapered, cone-like shape, coupled with its narrow neck, means that liquids inside it can be swirled without spilling easily. Additionally, the sides minimise loss of liquids from the flask when they are heated, as vapours condense on the sides.
What are the uses of elenmeyer flask in microbiology?
Erlenmeyer flasks are also used in microbiology for the preparation of microbial cultures. Erlenmeyer flasks used in cell culture are sterilized and may feature vented closures to enhance gas exchange during incubation and shaking.
What is an Erlenmeyer filter?
Filters The definition of an Erlenmeyer flask is a glass container used in laboratories with a cone shaped body, flat bottom and a narrow neck. An example of an Erlenmeyer flask is the most widely used laboratory flask.
