Know Everything About Pure Lab Water

What is Purified Water?

Pure water is obtained by processing the water from the natural resources through a series of stages. These processes remove all the contaminants present in the water to a negligible level. Water has a unique ability to dissolve substances, the impurities present in the water will reduce the accuracy and might provide wrong results in laboratory applications. Using purified water will help you get better results.

Benefits of Pure Water

It is important to use the purified water in the lab because the impurities present in the water will greatly impact the results. The Water purification system laboratory provides different water grades with different levels of purity such that purified water can be utilized with respect to the application economically.

The different level of purified water from the water purification system laboratory is, 

  • Type 1, also known as Ultrapure water system for the laboratory
  • Type 2, General Laboratory Grade Water
  • Type 3, Primary Grade Water

These types of water are used depending on the sensitivity of the application. It is important to understand the requirements of the laboratory applications and understand which  type of water is to be used effectively

How is water purified?

Different technologies are used to purify the water. Each technology has its advantages and limitations. A combination of these technologies is used to obtain the ultrapure water system for the laboratory. The latest water purification system for the laboratory enables you to monitor the purity all the time when you take water for laboratory applications from the water purification system. This helps you to ensure the consistent quality of the water you measure. 

Generally, there are different impurities present in the water like particles, inorganic, organic compounds, bacterial count, and more. It is important to pretreat the water before using it for the water purification system. Depth filters, activated carbon treatment are initially used to pretreat the water. Depth filters remove the particulates and activated carbon removes chlorine present in the water. These pretreatment technologies also help to reduce the amount of contamination prior to the water purification process.

This pretreatment of water before feeding into the water purification system for the laboratory prevents damage to the equipment and also enhances the purity of the water.

Water Purification System For The Laboratory

There are different purification technologies, the water purification system laboratory is designed with these technologies to enhance the quality of the water. Organizations such as ASTM, CLSI, and ISO provide you with the specific standards of each level of purity of the water. Lab Q provides you with a water purification system for the laboratory with the best design, easy installation, and maintenance.

Pure Water For The Lab

Lab purified water is used as a reagent, to prepare eluents, blanks, standards, solvent, rinsing glassware, and other cleaning purposes. Pure water is important in most lab applications. Depend on your lab purpose and the test analysis handled in the lab, a lab water purification system is chosen. 

Uses Of Pure Water

It is very interesting to understand the facts about the water in the laboratory. It is also important to understand how the contaminants in the water will affect your laboratory analysis. The contaminants of the portable water in your lab are to be determined and it is vital to determine how these contaminants may impact your laboratory applications. 

For example, Ionic contaminants may greatly affect the applications like trace analysis but organic impurities do not produce a negative impact on the results. But in the case of cell tissue culture, organic compounds affect the application results compared to that of ionic contaminants.

The common problems related to water contamination across various range of applications such as chromatography, nucleic acid, protein blotting, spectroscopy and spectrometry, histology and immunohistochemistry, and more are to be determined and the level of purity of lab purified water that is required is to be understood.

Contaminant Diversity

There are different types of impurities present in the water. It is important to understand how the water gets contaminated and how these contaminants can cause problems downstream. These are many tools used to test water purity. Determine the purity of the water accordingly the laboratory water purifier is chosen.

The Different Grades Of Pure water

A laboratory water purification system produces water with three levels of purity depending on the measurement of contaminants present in the water. The contaminants measured to determine the purity of the water are inorganic contaminants (Resistivity MΩ.cm), Total Organic Carbon (TOC in ppb), Bacterial count (CFU/ml), Endotoxin (EU/ml), and more. The different grades of water measured with their standard specifications are used in different applications. 

ASTM Standards for Laboratory Reagent Water

ASTM: American Society for Testing and Materials

ContaminantParameter (units)Type 1Type 2Type 3
IonsResistivity (MW-cm)> 18.0> 1.0> 4.0
 Silica  (ppb)< 3< 3< 500
OrganicsTOC (ppb)< 100< 50< 200
Particlesparticles > 0.2 um (#/ml) < 1NANA
BacteriaBacteria (cfu/ml)0.0010.110
 Endotoxin (EU/ml)< 0.030.25NA

It is more efficient and economical to use the right type of water as required by laboratory applications.

Water Purification Technology For Your Laboratory

It is important to understand how the water is purified at each level of the purification process to remove contamination. There are different technologies used and combinations of technology are used to produce ultrapure water systems for the laboratory. Different technologies are used to remove different contaminants from the water. It is best to choose a laboratory water purifier that uses the latest technology that removes the contaminants that affect your laboratory application to a negligible level.

Choose The Best Water Purification System For Your Laboratory

Before buying a lab water purification system several factors are to be taken into considerations like level of contaminants present in the feedwater, level of water purity of lab purified water required for your laboratory analysis, Technologies used in the lab water purification system, monitoring system to ensure the consistent purity of the water, capacity of lab pureed water required for your lab daily, long term requirement of lab water purifier, system features and lab water purification system price that is considered in your budget.

The Future Of Reagent Grade Water

The research scientist always focuses on increasing the sensitivity of the application to get accurate results. Development in technologies such as nanotechnology increases the necessity to enhance the sensitivity of laboratory applications. Challenges in the future with the most interesting research require to be done using ultrapure water.
