Chemical laboratory volumetric flask

A volumetric flask is a type of glass vessel that is used in laboratories. It is used to measure liquids. It is more accurate than other vessels. As it absorbs minute amounts of liquid; For example, if the volume of the flask is 500 ml, it can only hold 500 ml, and not more. It is worth noting that the volumetric flask is widely used by chemists, because chemical reactions require the use of minute amounts of chemicals.

Chemical laboratory Bunsen burner

Bunsen burners are a small gas, producing a single burner of flame, commonly used in chemical and school laboratories; It helps students to observe chemical reactions, and it is worth noting that the heat generated by this stove can be used to sterilize equipment, heat chemical reactions, or in combustion processes.

Chemical laboratory test tubes

They are a type of tube used in laboratories. Unlike a volumetric flask, most test tubes are not used to measure liquids; As they are not graded, but are used to carry and transport chemicals from one place to another, and their size ranges from 7.62 to 15.24 centimeters.

Chemical laboratory Centrifuge

One of the laboratory equipments is centrifuge. It is a device that moves liquids in a circular motion to separate their components. It is worth noting that centrifuges are divided into two types based on their size. [2]

Chemical laboratory conical flask

Erlenmeyer flask is a type of laboratory vessel that has a conical base and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer, who first made it in 1861.

Chemical laboratory Crucible

A crucible is a small cup of clay made of a material that withstands high temperatures, used to heat materials, and in addition, it contains a lid.

Chemical laboratory Inserted discs

Used cylinders listed for measuring fluid volume, be listed in numbers, and there are different sizes, it is worth mentioning that as the diameter of the smallest was the size measurement more accurate.

Other Chemical Lab Instruments

Here are some examples of other chemical laboratory tools:

Boiling flask (Florence flasks).

Watch glasses.

Funnel.

Droppers.

Pipettes.

Buret clamps Spoons (English: Spatulas).

Thermometers.

Chemical laboratory tools

There are many chemical tools that are used directly while working in chemical laboratories, such as:

• Analytical Balance: Also called a Mettler balance, this digital balance is used to measure mass with an accuracy of 0.1 mg.
• Centrifuge: A device used to separate the components of liquid samples by spinning.
• Pipettes: They are used to measure and transfer small amounts of liquid, and there are many types of them.
• Volumetric Flask: These flasks are used for the precise preparation and preparation of solutions.
• Spectrophotometer: A device that measures the intensity of light in terms of its wavelength.
• Gas chromatograph: An instrument used to separate the chemical components of a complex sample.
• Simple Microscope: It is used to magnify objects.
• Test Tubes: They are used for mixing, storing or heating materials.
• Graduated Cylinder: A precision instrument used to measure the volume of a liquid in mm.
• Test Tubes: They are used for mixing, storing or heating materials.
• Thermometer: It is used to measure temperature in degrees Celsius or Fahrenheit.
• Funnel: It is used to pour liquids into tubes with small openings.

 

Computational Chemical laboratory  tools

There are many tools and computer programs used by the medical chemist and help him in the stages of drug discovery, by providing tools that enable scientists to easily access information, calculate chemical properties and others, and some of these tools are:

1. ChemAxon: Provides many desktop tools, such as the Marvin drawing tool, as well as plugins for calculating a range of physical properties.
2. LigandScout: A software tool used to elicit a 3D drug.
3. StarDrop: It is a scientific chemical data analysis package that allows quick detection of synthesis activity, allows creation of multiple plots for data comparison, and selects matching molecules in the molecular data table.

 

The evolution of Chemical laboratory  tools

Chemistry is one of the sciences that deals with the properties and composition of the structure of materials, the transformations they undergo, and the energy that is released or absorbed during these processes. Wet chemistry methods, i.e. tests conducted using utensils, flasks and test tubes, and tests of reagents and other primitive means in chemistry, and with the advent of commercial laboratories, chemists relied on many specialized physical devices instead, and in the period between 1930-1970 the analytical revolution in chemistry contributed to the progress Science dramatically and rapidly, and brought about a radical change in the tools used in chemical experiments.
