Chemical Laboratory Equipment – This time we will discuss the equipment in the laboratory. What do we need a laboratory before? The laboratory is one of the centers for scientific activity which includes research, research, experimentation and measurement.
The laboratory is divided into three, namely the chemistry laboratory, physics laboratory, and biology laboratory. So, the laboratory tools used in a lab are different but some are the same with the same function. However, all laboratories have their own unique equipment.
For example, chemistry and biology labs, these labs have their own unique equipment. If a chemical laboratory has equipment such as measuring cups, measuring flasks, beaker glasses, drop plates and test tubes, the biology lab has equipment such as microscopes, magnifying glasses (loops), digital thermometers, stetoscopes, and human anatomy. Here we will see what are the tools in the chemistry laboratory.
Chemical Laboratory Equipment
So, the tools in this laboratory are used to facilitate research activities. Without this equipment, research and research cannot run smoothly and perfectly. So these tools are absolutely necessary and must be good tools or standard of use.
If you study Science or Biology, of course you will understand how the equipment is in the laboratory. On this occasion we will show you the equipment in the Chemistry lab, both in the lab at school and in research institutions.
1. Measuring Cup [laboratory equipment]
A measuring cup is a tool used in a chemistry lab to find out the volume of a solution. This glass is shaped like a transparent tube like a pipe with a slightly large bottom as a leg. This aims to maintain balance so that it does not fall.
There are various types of measuring cups in the chemical laboratory, ranging in size from 2 ml to 2 L. These cups are made of plastic (polypropylene) which is resistant and can be used sustainably.
2. Test tubes [laboratory equipment]
In the chemistry lab there are reaction tabs that are used to test the chemical reactions of a liquid. test tube is a glassware made of plastic or of glass. The size is usually 10-20 with a length of 50-200 mm.
Various activities such as mixing liquids, solids or heating chemicals are carried out in a test tube, the size of a human finger. But there is also a large test tube called a boiling flask.
3. Measuring flask [laboratory equipment]
A measuring flask is a device in a chemical laboratory that is used to dilute a certain solution to a certain extent. A volumetric flask can also be used to provide a high concentration of analytical solutions.
Usually, volumetric flasks are made in a transparent manner so that the chemical reactions can be easily controlled. There are also darkened gourd shapes with a lid that resists chemical and chemical reactions. This durable measuring flask is usually made of polyethylene.
The size of the volumetric flask also varies from 2 ml to 2 L.
4. Erlenmeyer flask [laboratory equipment]
Erlenmeyer flask is a flask model that is often used in various laboratories. This chemistry lab tool is made with a cone shape but the neck is round or cylindrical. The name of this tube was taken from a chemist from Germany named “Emil Erlenmeyer”.
Erlenmeyer flask is for measuring chemical substances, mixing or storing the liquid. The material for making it is also not arbitrary but from borosilicate glass, which is why it resists when heated. Erlenmeyer flasks range in size from 50ml to 500 ml.
Erlenmeyer flasks are also used in biology laboratories but have different functions, namely for microbial breeding.
5. Cup glass
The beaker glass used in the lab serves to accommodate. Usually in this glass tube used corrosive chemicals made of PPTE material.
The size of the beaker varies from 25 mL to 3 L, it is made of plastic or borosilicate.
6. Dropper pipette [laboratory equipment]
This pipette serves to take chemical fluids or move the measured liquid. This equipment is made of various sizes and shapes according to its function. Types of pipettes include measuring pipettes, dropping pipettes and volume pipettes.
Dropper drops, it is able to move liquids on a very small scale for example a few drops. The shape of this tool is in the form of a small pipe with a rubber cover at the top. The trick is to squeeze the rubber part and the water will enter a drop or two in a small amount.
7. Measuring pipette [laboratory equipment]
This pipette is used to move the solution to a certain place according to the dosage, the pipette itself has a size to make work easier. Typical pipette size is 50ml. So, with this pipette the lab worker can pour out as much liquid as he likes easily.
8. Volume pipette / goiter [lab equipment]
The next laboratory tool is the goiter pipette or volume pipette, this is different from the drop pipette. Its large size makes it easy for you to move large liquids from one place to another without fear of an incorrect measurement.
This tool in the middle is in the form of a bubble or expands, this is the reason why it is called a goiter pipette. With the presence of these bubbles, it makes it easier to transfer the liquid to the exact volume as written on the bubble section.
9. Tripod [laboratory equipment]
This is a three-leg iron as a support ring, it is useful as a wire mesh or support when heating the tube.
10. Test tube rack [laboratory equipment]
The test tube rack is a shelf for storing test tubes which are usually made of wood with 6 holes and six basins so that the test tubes can be very strong and do not collapse. Test tube rack size is usually 20 x 10 with the six holes.
On one side, there are six logs that serve as a drying area for the test tube.
11. Test tube clamp tool [chemical laboratory equipment]
The test tube clamp is made of wood and at a glance is similar to a cloth clamp. This tool is used when the test tube heating process.
12. Drop plate [laboratory equipment]
There is also a name drop plate, this is a laboratory tool in the form of a container to test the acidity of the solution. This tool is made of porcelain, and the number of holes is usually 6, 12 to 16 holes.
13. Mortar and Alue (Pestle)
Mortar and pestle, which in Indonesian are called lesung and pestle, are two ingredients that complement each other to smooth and break solid zazt. The dimple is the container and the pestle is the breaking device.
This lab tool also exists in biology laboratories but its more common use is to destroy various experimental materials such as leaves, seeds, destroy roots, proteins, destroy DNA, RNA and others.
14. Wire gauze [chemical lab tools]
Gauze in chemical laboratories is used to hold a flask or beaker when heated with a bunsen or a spirit heater.
At the bottom, chemical equipment in the form of a tripod is also installed so that the heating process can be maximized.
15. Nichrome wire
Materials or tools in chemical laboratories also exist in the form of wires. This wire is called nichrome, which functions to try or test the flame of a substance.
16. Separating funnel [chemistry lab tool]
This separator is used in the chemistry lab, especially when it comes to liquid extraction. This separation funnel is half spherical at the top and at the bottom there is a tap.
This tool is made with borosilicate glass and faucets made of glass or Teflon.
