Applications Of Water Purification

Lab water purification system for laboratory plays a pivotal role in lab applications and experiments. Researchers and scientists set an ideal lab water system in the laboratory to get better results out of the experiments. Pure water or lab water is preferred over normal tap water due to its zero contamination. Usually, tap water contains contaminants which are also called impurities. These contaminants alter the experiment results and thus results in inaccurate experiments.

To obtain the right purity of water, lab fellows install water purification systems that produce pure water with ease. The lab water system is designed to help the researchers and scientists in their lab applications and scientists. A laboratory water purification system price is also affordable which makes it more approachable. Several applications of lab water systems prevail in the laboratory which takes the use of water. 

Pure water or lab water is an essential reagent in the laboratory which assists the researchers in getting accurate results. The lab water purification system is one such component of the lab that aids in all applications where pure water is required. 

Applications Of Laboratory Water Purifiers

A laboratory is full of experiments and applications related to water. Without lab water, it is tedious to perform any experiment. Any kind of water purification system for laboratory use that uses the produced pure water. 

Following are some of the top applications of lab water purifiers:

1.  In Liquid Chromatography

The first application of a water purification system for  laboratories is liquid chromatography. It is used to separate mixtures of species from a solution.  The species are separated by this technique which is popular in the lab due to its efficiency. Liquid chromatography comes under the name of powerful tools for analytical studies. It includes the separation and analysis of mixtures of compounds. When combined with mass spectrometry application, the liquid chromatography becomes more powerful in the separation technique.

Impact Of Pure Water In Liquid Chromatography

In this application of the lab water purification system, pure water is required in large amounts.  The purity of water is a very critical point here, especially in the cases of high sensitivity experiments.  Liquid chromatography requires water in pre-treatment phases as well as in the preparation of eluents. The reagent blank and standards are also prepared by the use of water. In the liquid chromatography process, one cannot use the normal tap water as it contains many impurities that can drift the results of experiments.  A lab water system is used to produce large amounts of pure water to execute this application.

Liquid chromatography is highly sensitive to impurities. So, it is said to only use ultrapure water while performing this application.  The purity of water should be evaluated first with the help of a water distillation unit for laboratory. The water used here should be free of any type of contamination to get better results. The total organic content should also be checked for assurance.

2.  In Spectrophotometry

Spectrophotometry is a widely used application of a laboratory water purifier. It is used to determine the presence of any substance in the sample solution. It is done by measuring the amount of light getting absorbed by the sample solution. Here, the light should be in a particular wavelength of ultraviolet and visible length(185-700nm). With the help of spectrophotometry, quantitative analysis can be done. The analysis ranges from pharmaceutical quality control to water analysis methods. In spectrometry,  the analytes can include metal ions, phosphate, hardness of water, detection of proteins, Sulphates, DNA, and RNA.

Impact Of Water On Spectrophotometry 

In this application of spectrometry also, pure water is required in abundant amounts. The purity of water is also an important part here. Without pure water from a lab water system, spectrometry is not performed. The sensitivity of this application makes it more water-driven. The slightest impurity in the lab water can alternate the results of an experiment. 

In spectrophotometry, pure water is required for the following :

  • Pre-treatment of reagents
  • Preparation of reagents
  • Preparation of blanks
  • Preparation of standard solutions

The impurities should be discarded before executing the experiment. All solutions used in this application should be obtained through water purification systems for laboratory in abundance and the right purity. The Water systems are well designed to serve this application of laboratory with ease. When right pure water is used,  it shows great results when UV light gets absorbed by the solution.  Hence, it is advised to prepare all standard solutions and samples using pure water or lab water.

3.  In Microbiological Analysis

For any lab, microbiological analysis is one of the most used applications of a lab water system.  The microbiological analysis includes the analysis of every type of microbiological entity in it. The microbiological entity can be:

  • Bacteria
  • Viruses
  • Protozoans
  • Fungi

This analysis not only detects the presence of microorganisms but also enumerates the amount of them. The application is applied often in disease-causing samples and spoilage due to microbes places. The most common microbiological analysis are as follows:

The analysis can be quantitative as well as qualitative in nature.  It all depends on the type of research work you are required to do. Immunoassays are also done with this method.

Impact Of Water On Microbiological Analysis 

The detection and isolation of microorganisms are done with the help of pure water. It all depends on the type of water you are using in this application.  The water should be devoid of any kind of impurities like endotoxins, dust, etc.  Lab water purification systems for laboratory serve the purpose of producing pure water for the successful detection of the microorganism. In microbiological assays,  water is used to prepare culture mediums which consist of 99% of water.  It is useful in avoiding any kind of contamination in the water that can negatively impact the lab results.

To some extent, water is also used for executing autoclaving in the lab.  The highly sensitive ELISA requires pure water in every step of the procedure. So,  it is highly advised to use pure water when performing such microbiological applications and experiments. For cleaning the dishwashers and other related accessories of the lab, pure water from the water purification system is used. In PCR, the nuclease-free water is used to prevent any type of impurity build-up.

4.  In Clinical Biochemistry Analysis

This application of water purification systems for laboratory is very important.  Clinical Biochemistry application covers a wide range of biochemical tests, in vitro chemical tests on body fluids and tissues.  It is done to support the diagnosis in the patient’s body for monitoring the disease. Clinical biochemistry analysis provides two types of diagnostic testing on the human body:

  • Using large fully automated analyzers for testing purpose
  • Immunoassays

The samples are loaded in sample tubes that are further tested. Some colorimeter agents are also used for the detection of the disease.  However, some immunoassays are also there that use antibody enzyme target recognition. 

Impact Of water On Clinical Biochemistry 

Biochemical analysis is based on the testing of liquids and other liquid suspensions. For this purpose, high purity of water is required, from the laboratory water purifier.  Pure water is used in biochemical assays in diluting the samples, further processing of solutions, washing sample tubes, etc. In such cases, the poor water or tap water cannot be used as it can interfere with the tests and thus produce inaccurate results. This application is sensitive to contaminants like bacteria, endotoxins, large chunks of other metal ions, etc.  Lab water is useful in every phase of such biochemical assays application. 

5.  In Cell and Tissue Cultures

Cell and tissue cultures are the type of cultures that are used to monitor the growth of cells and tissues. The cultures are done in a favorable environment so that cells and tissues can proliferate easily and fully. The factors can be controlled by regulating the amount of pure water, temperature, etc.  

Impact Of Water On Cell And Tissue Cultures 

If any cell and tissue culture are done under the influence of poor or tap water, there are fair chances to get contaminated results. To avoid such results, the use of pure water is recommended for performing cell cultures.  Pure water from a water distillation unit for laboratories is used in every step of cultures. The main component of such cultures is the preparation of media and buffers, additives solutions, etc. It is said that the implementation of purified water from water purification systems for laboratory is useful in getting successful results of cultures.


As it is clear that a laboratory water purifier is an important component of any lab. It has varieties of applications in which the right purity of water is required to get better results.
