Tap water has a variety of different impurities, including ions/salt, bacteria, organics, and nucleases. While the levels of these impurities in the water are safe for human consumption, they are not ideal for the different applications in your laboratory. Some consequences of the impurities can be clogged filters, left behind mineral deposits in lab equipment, or even cause morphology issues with cell and tissue culture. Enter your water purification system.
Water purification systems are a critical component in most labs in avoiding the consequences from impurities. Itis important to choose the right one to fit your application, which can be a daunting task. In order to reduce the frustrations in selecting a water purification system, it will be helpful to keep a few things in mind.
First, determine what type of water you need in your lab – ultrapure? Pure? Reverse Osmosis? You may think it is a good idea to go for the highest level of water purity and get an ultrapure water system for all your applications, but ultrapure water is actually not a good option for all lab applications. Identifying what application the water will be used in will help determine the type of water you need, and the water purification system that will work best.
Second, consider your budget. It is important to understand both the upfront and annual maintenance costs of a system. Make sure you ask the sales representative the right questions so you are able to pick a system within your budget.
Third, determine the features that will improve your workflow. You will quickly notice that most companies offer multiple systems for each water type. For example, Thermo Fisher Scientific offers the Barnstead™ GenPure™ xCAD Plus Water Purification System, Barnstead™ MicroPure ™ Water Purification System, and the Barnstead™ Smart2Pure™ Pro Water Purification System which all will produce Type 1 water. Keep those above tips in mind when determining what will work best for you and your lab.
