A widely lab glassware - glass beaker

glass beaker

Glass beaker is almost the most wildly used laboratory glass, it is a simple container for stirring, mixing and heating liquids commonly used in many laboratories. Glass beakers are generally cylindrical in shape, with a flat bottom. Most also have a small spout (or "beak") to aid pouring as shown in the picture. Glass beakers are available in a wide range of sizes, from one milliliter up to several liters.

 

today we will share some tips and information about this useful tool.

 

1, There is a volume scale on the beaker, but the beaker can not be used as a measuring device.

 

2, The beaker can only measure the solution of a certain volume.

 

3, The beaker can heating, the thickness of the bottom of the beaker is not uniform, so the beaker generally put on a tripod pad asbestos net heating, so you can at the bottom of the beaker is heated evenly, not at the bottom of the uneven heating lead to burn out the bottom of the beaker,

 

4, When dissolving some soluble salts in a beaker, use a glass bar/stirring bar to stir constantly to make it dissolve faster.

 

5, How will the liquid into the beaker inside? You can use glass rod liquid drainage into the beaker, specifically a glass rod close to the inside of the beaker, the liquid slowly poured into a glass rod, liquid in the glass rod slowly flows into a beaker inside.

 

6,  How do you transfer the liquid in the beaker to other solvents?  The mouth of the beaker has a prominent small mouth. The small mouth is close to the mouth of the container, pouring the liquid from the mouth of the beaker and pouring it into the other container,

 

 

7, when the medicine is weighted, the beaker can be used as a container, but it should be peeled when weighing, It should be noted that the beaker can not be used as a long lasting solution reagent bottle.
