The Uses of Vacuum Aspirators

As its name indicate, a vacuum aspirator is laboratory equipment used to suck different types of liquid from variable laboratory vessels i.e. beakers, petri dishes, flasks, etc. Previously, the suction of liquids in the laboratories was done with a micropipette and other laboratory equipment, but the arrival and invention of these vacuum aspirators have made the performance in the laboratories much easier and effortless. 

Components of the Vacuum Aspirator

The vacuum aspirator mainly contains the following components: 

• The Base Bottle: The base bottle to collect the unwanted liquid that is sucked from the laboratory vessel. 

• Transferring Tube: This is attached to the bottle and the aspirator handle to pass on the unwanted liquid from the beaker or petri dish to the collection bottle. 

• The electrical wire: this is mainly attached to the power supply button in the laminar flow hood or at the wall. 

• Vacuum Level Indicator: The vacuum levels are mentioned on the display, you need to select the particular vacuum level and thus turn on your knob so that the exact vacuum can reach up to the mark and thus the liquid will be pulled inside the collection bottle for withdrawal from the laboratory vessel. 

How does the Vacuum Aspirator Suck Liquids in laboratories? 

The aspiration pump creates a vacuum in the bottle of the aspiration and thus, due to the differential pressure inside and outside the aspirator, the liquid usually gets pulled inside the collection bottle thus, when the collection bottle gets full, the unwanted extra liquid disposed of out of the collection jar. In addition, before the application of pressure, the vacuum level must be adjusted and it should be up to the mark on the vacuum level indicator so that, the specific pressure would be applied and pulled liquid out of the laboratory vessel. 

The Principal Uses of Vacuum Aspirator 

Previously in labs, micropipettes were used to pull the liquid out of the liquid laboratory vessels, but for more convenience and easiness, the researchers are now using these vacuum aspirators to pull the unwanted liquid out of the laboratory vessels like beakers, petri dishes as well as conical flasks. The certain uses of vacuum aspirators in medicinal, biological, radioactive, and even science laboratories are as follows:

• To pull the media from Petri dishes during the cell culture process, this vacuum aspirator is used frequently in the laminar flow hood. The media is sometimes the liquid and the semi-liquid material, so thus by applying the pressure, the vacuum aspirator pulled off the previously utilized media by the eukaryotic and prokaryotic cells inside the petri dish. 
• To withdraw the supernatant liquid from the beaker or the conical flasks to purify the remaining sample material for accurate and precise results, these vacuum aspirators are frequently used in laboratories. 
• To extract the minute elements like the RNA/DNA from the sample material, these aspirators are required in the biological laboratory. 
• For the separation of the biological immunology elements from the rest of the sample materials, these vacuum aspirators are used in everyday experiments by the researchers. 
• These vacuum aspirators in the laboratories usually do the separation of liquids and solids and even the liquid recoveries whether it would be biological, chemical, or even the radioactive lab.

General Structure and Uses of Vacuum 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. In addition, this is one of the most advanced forms of vacuum pump. 

Conclusion 

The uses of vacuum aspirators are beyond words since this laboratory equipment has become the most required and wanted apparatus in this era. The most crucial thing for any researcher in any laboratory while pursuing experiments is the accuracy and precision of results. Moreover, these can never be achieved without the usage of vacuum aspirators. This suction equipment helps the researcher have the most accurate readings of whatever he is doing in the lab. Even while measuring the pH of any liquid, this is necessary that the liquid must be free of any mixture or any unwanted fluid and this can only be done by the use of the vacuum aspirator equipment. This helps the researcher in getting rid of the unwanted fluids and thus, the result he gets at the end of the experiment is pure and precise. However, the limited usage of the vacuum aspiration machine in labs can result in the results biasedness and failure of the experiments in terms of false readings and false positive results, so the usage of the vacuum aspirator has become necessary in this regard for the unbiased and accurate precise readings and end experiment results.
