Why do scientist use a beaker?

Beaker – A beaker is a glass container with a flat bottom and a small spout for pouring. It is used in the chemistry lab for mixing, heating, and stirring liquids. It is used in the lab for heating and sterilizing.

How do you use a beaker?

Pour liquid into the beaker; pour slowly to avoid splashing the liquid. Use the measuring lines on the beaker to approximate the volume of liquid in the beaker. Stir the liquid inside the beaker with a spoon or stirrer.

What does a flask look like?

Round-bottom flasks are shaped like a tube emerging from the top of a sphere. The flasks are often long neck; sometimes they have the incision on the neck, which precisely defines the volume of flask.

What are the lines on a beaker called?

What is a meniscus? A meniscus is what happens when you put a liquid into a container. When you put water in a beaker or test tube, you see a curved surface. With most liquids, the attractive force between the liquid and the container is greater than the attraction between the individual liquid molecules.

Can a beaker be heated?

A beaker is a cylindrical container used to store, mix and heat liquids in laboratories. Center the beaker on a burner or over an open flame to heat the liquid, if necessary; don’t fill the beaker more that 1/3 when heating and always use safety tongs when handling a hot beaker.

What is a triangular beaker called?

An Erlenmeyer flask, also known as a conical flask (British English) or a titration flask, is a type of laboratory flask which features a flat bottom, a conical body, and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer (1825–1909), who created it in 1860.

What to do if you break a beaker?

Broken Lab Glassware Injuries

  1. Allow the wound to bleed, but do not massage it to remove any remaining broken glass.
  2. Wash the wound with warm water and soap.
  3. Apply first aid and seek medical attention.
  4. Follow your facility’s safety plan if the injury is severe or if you were exposed to infectious materials.
