What is beaker and uses?
A beaker is a cylindrical container used to store, mix and heat liquids in laboratories. Most are made of glass, but other non-corrosive materials, such as metal and heat-resistant plastic, are also used. Beakers usually have a flat bottoms and a lip around the top.
What are the three uses of Beaker?
Beakers are often used to hold, mix, and heat reagents. Most have a small lip for pouring liquids. Test tubes, which are relatively small cylindrical vessels, are also used to store, heat, and mix chemicals.
What are pipettes used for?
To transport a measured volume of liquid
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. Beakers come in various sizes and are shaped like a cylinder. It is used in the lab for heating and sterilizing.
How are pipettes used in a lab?
Pipettes are an essential laboratory tool used to dispense measured volumes of liquids. Pipettes most commonly work by creating a partial vacuum above the chamber that holds the liquid and selectively releasing this vacuum to draw up and dispense according to the preferred volume.
What are the three different types of pipettes that are commonly used in lab?
3 Different Kinds of Serological Pipettes
- Open-End Pipettes. Open-end pipettes are specially designed pipettes that feature open-end for use with higher viscosity liquids.
- Bacteriological Pipettes.
- Aspirating Pipettes.

What is the importance of beaker A in the experiment?
In laboratory equipment, a beaker is generally a cylindrical container with a flat bottom. Most also have a small spout (or “beak”) to aid pouring, as shown in the picture….Beaker (laboratory equipment)

What is pipette used for in microbiology?
Pipettes are an essential laboratory tool used to dispense measured volumes of liquids. Pipettes enable sterile and accurate liquid handling and are commonly used within molecular biology, analytical chemistry and medical tests. …
What is burette used for?
burette, also spelled buret, laboratory apparatus used in quantitative chemical analysis to measure the volume of a liquid or a gas. It consists of a graduated glass tube with a stopcock (turning plug, or spigot) at one end.
What are serological pipettes used for?
The serological pipette is a nearly ubiquitous laboratory instrument used for transferring milliliter volumes of liquid. Serological pipettes typically have gradations along their sides for measuring the amount of liquid being aspirated or dispensed.
What is a beaker tongs used for in chemistry?
Use beaker tongs to handle hot beakers. These nickel-plated steel tongs are 25 cm (10″) long and have plastic coated jaws that open up to 11 cm (4.5″). They can hold beakers ranging from 100 ml up to 1000 ml.
What is a beaker used for in a lab?
Beaker (glassware), or “laboratory beaker”, a glass object used for holding fluids and chemicals in a laboratory setting.
What are some uses of the beaker in a laboratory?
Each has a unique form and purpose Beakers are the workhorse glassware of any chemistry lab. They come in a variety of sizes and are used for measuring volumes of liquid. There are multiple types of flasks. One of the most common in a chemistry lab is an Erlenmeyer flask. Test tubes are good for collecting and holding small samples.
What is the use of Beaker in laboratory tools?
A beaker is a common container in most labs. It is used for mixing, stirring, and heating chemicals. Most beakers have spouts on their rims to aid in pouring. They also commonly have lips around their rims and markings to measure the volume they contain, although they are not a precise way to measure liquids.
How do you measure a beaker?
With an electric balance, the number given will be the mass of just the water. With a triple beam, subtract the mass of the beaker that you measured earlier from the mass of the beaker with water. For volume, pour the water into the beaker— although, sometimes a graduated cylinder can be easier to read.
