Let's talk about lab water
People with kidney disease receiving dialysis are exposed to hundreds of litres of water every week. So, it’s possible that even tiny traces of bacteria and endotoxins could have detrimental effects.
In fact, the quality of their dialysis-water can contribute to inflammation – the natural defence the body takes on when it is under attack. Chronic inflammation is not good news for people with kidney disease. It is a potent trigger of cardiovascular disease and can also contribute to anaemia. All in all, it increases the chance of losing their lives.
A team of scientists at the University of Naples set out to investigate if using improved ultrapure water is a better choice for people receiving dialysis for kidney failure. In a small prospective study involving 32 patients, their results suggest that using an additional ultrafilter to improve dialysis-water quality may indeed have health benefits. (Reference: https://link.springer.com/article/10.1007%2Fs40620-017-0422-x) Patients receiving this ultrapure water had improved haemoglobin levels and a reduction of inflammation markers in their blood. As a result, they were able to reduce their medication to treat their anaemia.
Although these results remain speculative, the researchers hope it will lead onto bigger studies to investigate whether using improved ultrapure water can reduce inflammation and improve survival for patients. With almost 30,000 people on dialysis in the UK alone, the impact could be huge.
These exciting new clinical results won’t necessarily be a surprise for research scientists.
In a similar way to patients receiving dialysis treatment, even the tiniest traces of impurities can have detrimental effects on sensitive experimental laboratory techniques. If you have already experienced frustration from water impurities impacting on your ability to achieve consistent, accurate results, the good news is that it’s one factor that’s easily avoidable! Removing water impurities is essential for many experiments and easy to achieve by using a guaranteed and reliable source of ultrapure water in the laboratory.
But if you’ve ever explored this further, it’s easy to feel overwhelmed – as there are a wide range of water purification techniques and a plethora of measurements and standards to gauge quality.
However, help is at hand from the experts at ELGA LabWater.
We have an easy reference list of common applications and the water purity you need. Check out our handy categories:
And we also have a range of ultrapure water purification systems that can be installed in your laboratory, so you can have a source of high-quality ultrapure water on tap.
So, the next time you’re experiencing the pain of an experiment that stops working, or if you’re struggling to achieve a reproducible result – it could be as simple as checking that your lab water is of the right quality to give you the best chance of success!
