What is the Laboratory Tools?
Laboratory containers are the first important requirement of any laboratory equipment, in general, laboratory containers should be very resistant to all kinds of chemicals due to their proximity to different chemicals. Their resistance is not only limited to resistance to chemicals, and in many users who need to cool or heat, they will be exposed to cold or heat, and as a result, it is necessary to have high thermal resistance.
Erlen: Erlens are similar to humans, but they have a thin and narrow mouth and are used to store liquids, and during handling, the possibility of spilling the material is very low. And one of the advantages of using Erlenmeyer flasks is that the solution inside is narrowed so that it can be mixed easily.
Test tube: Test tube is one of the most widely used tools in laboratory and laboratory equipment. is It is in the form of a small cylinder, the bottom of which is closed and the head is open, the material of the test tube is glass, and the use of this tube is to store various solutions and samples.
Laboratory balloon: It is a container balloon which has a narrow opening and looks like a pear or very much like a flower pot. Balloons deliver heat to the substance in a balanced way, it is very suitable for heating and boiling and is also used for distillation. and this cylinder is used to measure the volume of solution and liquid inside it. The accuracy of this cylinder is much higher and more accurate than that of humans. >Pippet: A pipette is a device that we can accurately remove a liquid or solution from a container and transfer it to another container according to the degree it has on its body. The basis of the work of the pipette is in the form of suction, that is, it pulls the solution into itself until the suction force is established, the solution is inside it, when it is released, the solution is discharged from the pipette and sent to the desired container.
Laboratory alcohol lamp: The laboratory alcohol lamp is one of the most important laboratory equipments, which has a tank filled with alcohol, a wick is inserted into it, and its flame is smokeless. In the laboratory, an alcohol lamp is used to sterilize loops and needles, etc. The alcohol lamp is a cylindrical glass container with a wide mouth with a cap and a cotton wick. The cap above the wick that is inside the alcohol is used to extinguish the flame and prevent the alcohol from burning and evaporating. It is made of metal and has three legs and a holder on it. The three legs of the laboratory can be used for:
heating the laboratory vessels with the help of a flame
for cooling hot vessels
fireproof mesh or The fireproof triangle is placed on the tripod
It is resistant to heat
The laboratory tripod is very light
Desicator device: The popular and widely used desiccator device in laboratory equipment has 2 models, which include:
Desiccator model (Vacuo-Temp)
This model of desiccator is like a pot and is made of glass or metal that air cannot penetrate inside and for keeping laboratory chemicals that are sensitive to humidity. are used. Also, this device is used to dry materials such as soil by vacuum or to prevent the penetration of excess moisture by silica gel.
