The rubber pipette bulb In The Laboratory

There are very varied materials from which they find the laboratory instruments and materials made. Some are more common than others so a certain classification can be made based on them. Among these elements we can name metal, plastic, wood, ceramics, rubber, among others. Rubber is a very diverse element and laboratory materials with this material are very durable. Today
you will know one of its exponents, discover 7 functions of the rubber pipette bulb in laboratory.

What is the rubber pipette bulb in the laboratory? 🧡👨‍🔬

It is a rubber device that receives the names of perilla, perita or rubber pipette bulb and is used in laboratories. In order to suck a liquid into some glass or plastic material. It is a complement that facilitates the function of other materials such as droppers and pipettes. They were created to ensure safety in the transfer and measurement of liquids.

Types of rubber pipette bulb in the laboratory ❤︎

They basically fulfill the same function but differ by the predominant material in its structure and for its specific use. Prune finding two well-differentiated types:

• Only rubber: They are those that are composed entirely of soft rubber very similar to those used in the care of babies to aspirate fluids from your nasal passages. They are usually used with droppers and they have a very famous exponent known as propipeta. Which is a pear of suction that has some valves to improve and facilitate its work.
• Rubber and plastic combination: They have a mechanism a little more complex but they have the same functionality. They have as main feature a wheel that depending on the direction it is turned suck or release the liquid.

What is the rubber pipette bulb for in the laboratory? 👩‍🔬🌡

This laboratory material is a complement to other measuring instruments whether made of plastic or glass. So your first functionality would be to help or contribute to the functions of these instruments. Mostly rubber pipette bulb is used in the laboratory with it counts drops and with pipettes. Then we can say that it serves to suck liquids of all kinds either to make a measurement. O even to safely transfer the same.

How is the rubber pipette bulb used in the laboratory? 🔬🦠

It is very simple to use and this only makes it much more fabulous in its functions. This rubber accessory fits the upper part of the instrument to be used (pipette or dropper). Must be fixed
firmly in this opening of the other instrument. Then we will just press the center of it, which will generate a certain vacuum. This part must be done out of the liquid, once done then it is introduced to the liquid. Freeing from a little the pressure on it, in this way the liquid will be sucked out. For to release or dispense the same, we must press the center of the pear again.

In the case of the propipeta modality there is a certain difference in this method of use. Since she specifically has three valves with which this whole process is handled. With a propipeta the process would be as follows:

Fits the selected pipette, we extract the air by pressing the valve with the letter A (located at the upper end) and press the center of the bulb. At the moment of raising the liquid we press the one that it has the letter S (located on the side) and finally to dispense the liquid we press the letter E (which is located at the bottom).

On the other hand, the double material propipetas have a mechanism designed to employ only one hand in its use. Only one should be turned wheel that controls both the suction and the removal of the liquid.

What is the function of the rubber pipette bulb in the laboratory?

This laboratory instrument fulfills a function basic that is to transfer liquid from one container to another safely. But this function goes beyond the simplicity of these terms, since this it is a security tool. So it protects us from exposure to harmful, toxic and corrosive substances. Since it eliminates the need to exercise suction directly with the mouth.

Maintenance of the rubber pipette bulb in the laboratory

No large procedure is needed to perform the maintenance of this laboratory material. It can be performed as a any other rubber element, a correct disinfection with some substance
non-corrosive. In addition to this, avoid subjecting it to high temperatures that modify the properties of the gum itself

Now yes, you already know 7 functions of the rubber pipette bulb in the laboratory that you did not know until now. Although it may seem like an expendable laboratory material, this is one of the elements that are necessary just for the safety of the operator. Do not forget to visit other of our publications to know a little more about this world of laboratory materials.
