What Is The Main Function Of Aspirator?

The Main function of the aspirator is to produce the vacuum by the Venturi Effect. This is also called the filter pump. The vacuum aspirator applies the pressure and forces the liquid using high velocity. In each aspirator, a fluid can be gaseous or liquid. This liquid will ultimately flow through the narrow tubing when the pressure is applied. In addition, once the tube becomes thin, the speed of the fluid will similarly increase and accelerate. This is all because of the Venturi effect that is mentioned above. 

Function of Aspirator in Cell Culture 

Cell Culture:

When the eukaryotic or prokaryotic cells are cultured in laboratories and grown artificially within the biological incubators, with the help of some ingredients necessary to produce the cell within a petri dish, these are called cell cultures. The cultural cells can be multicellular or even single. The most common cells that are cultured in the laboratories are bacterial as well as fungal cells. 

Function of Aspirator and its Effect on Cell Culture 


The aspiration or suction in the laboratory is mainly used to remove the cell media in biological laboratories. The cell cultures principally contain some medium on which the living cells grow. These media, later on, suck by the aspirators available in the laboratories so that another medium will pour into the petri dish for the growth of other kind of living cells. There are different media required for specific single-cell organelles. 

The cell cultures are intended to proliferate or facilitate the growth of living cells, providing them with essential nutrients and minerals to cultivate. The aspirator is further used to suck the media that is metabolized by different living cells by using a vacuum. 

The aspirator is also used to dispose of supernatant liquids from the lab vessels in the laboratory, whether a chemical, biological, or medical laboratory. In addition, the extraction of the DNA/RNA, microplate waste removal, withdrawal of biological and immunological reagents, and other separation of liquids and solids and even the liquid recoveries are usually made by these vacuum aspirators in the laboratories whether it would be biological, chemical or even the radioactive lab. These aspirator systems are mainly versatile and can be used in a single lab for various purposes. 

Benefits of Using a Vacuum Aspirator 

  • The vacuum aspirator reduces the chances of liquid encountering the outside environment, thus making the sample contamination-free and providing ease to the researcher in lab experiments. 
  • The vacuum aspirator also carries the lab experiments and offers convenience in transferring liquids from one lab vessel to another, from a beaker to a flask and from a petri dish to the collection jar. 
  • The vacuum aspirator helps the researcher efficiently handle the lab liquid waste rem. Oval left the pure sample behind in the lab flask
  • The vacuum aspirators assist in mechanical fluid handling and productively increase productivity and lab operations. 
  • In addition, this lab apparatus effectively handles various other fluids, e.g. water, different bases, alcohol, some dilute acids, etc. 

Specific Features and Functions of Aspirator (Ispirator)


This powerful aspirator has a dual-head brushless pump that further increases the pump’s longevity to speed up the aspiration’s performance compared to the traditional ones. These Ispirators are mainly used to suck the required amount of liquid in the laboratory, such as next to tissue culture hoods or as the powerful benchtop aspirator. 

These aspirators are also used in the laboratory to remove liquid waste safely and effectively. This is the most advanced form of the vacuum pump. 


The vacuum aspirator mainly works on the Venturi Effects, and thus, the function of the aspirator is to suck the liquid by applying vacuum pressure. These aspirators can be used for various purposes, such as disposing of supernatant fluids from variable laboratory vessels like Petri dishes, flasks, beakers, etc. Also, for the extraction of RNA/DNA, removing media from the cell culture, withdrawing biological immunology reagents, and incorporating other media into the Petri dishes. Microplate waste removal in the laboratory is also used to separate one liquid from another and separate liquid fluids from solids. These are the effective lab apparatuses to clear the samples for further examinations in the laboratory. 

An aspirator can never be a micropipette, as this runs on an electrical source, and the micropipette uses suction from the mouth with the thumb to retain the required amount of liquid in the tube. However, the vacuum pump contains a housing container and tube along with a vacuum to suck the necessary amount of liquid via a tube with the help of preexisting vacuum pressure.
