Water is the most used reagent in the laboratory. Its quality has a direct effect on your assays. Poor water can shift results, reduce reproducibility, and requiring tests to be rerun. Good water supports reliable results. In this short video series, we explain what you need to know about water in clinical diagnostics, from reading the label to choosing the right grade.
Water in clinical diagnostics: which water to use and why?

Which water to use and why?
What is the label on your water?
Distilled water, demineralized water, deionized water, ultra-pure water… Which one is right for your biochemistry assays?
Water is a reagent. Like any reagent, it comes with a label — and the label matters.
In this short video, we show you what to look for: the water type, the purity specifications, and the storage and shelf-life details. Reading these correctly helps you choose the right water for your assays and avoid surprises in your results.
This is the first video in our series on water in clinical diagnostics.
What is hiding in your water?
Ions, organics and microbes can change your results.
Water looks clean, but it is never empty. It can carry dissolved ions, organic carbon, bacteria, and small particles. Each of these can interfere with your assay and shift your results.
In this video, we explain the main types of impurities and how they affect biochemistry testing. Knowing what to look for is the first step to more reliable results.

What kind of water should you use?
For most biochemistry assays, type II purified water is the right choice.
For most biochemistry assays, type II purified water is the right choice. But how do you know if your water meets the standard?
In this video, we go through the key values to check:
- Conductivity below 1 µS/cm
- Total organic carbon (TOC) below 50 ppb
- Bacterial content below 100 CFU/ml
We also share two practical tips: always verify the supplier's specifications, and use the water within seven days of opening.

How is pure water made?
Pure water does not come from the tap. It is made. Different methods remove different impurities, and each has its strengths.

In this video, we explain the main purification methods — filtration, reverse osmosis, and deionization — and what each one removes. This helps you understand where your water comes from and why the grade on the label matters.
