Does anyone know which material between glass or plastic is more suitable for pharmaceuticals and/or wastewater toxicity testing? Which is the one that will less affect the concentration of test substances in solution?
Thanks a lot!
Hello Arianna Bellingeri ,
What exactly are you testing for? The answer will very much depend on this.
In my experience, it is best to contact the relevant agency that performs the sample collection. For example, in the UK it is the Environment Agency. They often have protocols and particular apparatus that they use. Therefore, in practice, successful commercialisation of tests often involves aligning with these pre-existing protocols.

Hi Arianna, both won't affect the concentration of test substance in solution. However, if you are working in a lab then glasswares are the best to use. In case, if you are bringing samples from field then plastic containers can be better from transport point of view, however, if you have small samples then prefer using glass containers. Plastics can give leachates, which can come to your sample unncessarily.
Hi, thanks for your answers!
I am planning to do Daphnia magna reproduction test, but I will also need to use other organisms to test the effects of pharmaceuticals and wastewater, so I was trying to understand which material is best to use. I would rather use glass than plastic, as it is reusable and can be cleaned thoroughly, but I know that, for instance, for metal testing plastic labware is recommended as metals are more likely to adsorb on glass and that would affect test concentration.
Hi, good to know the info. from you. So from that point of view, you can use plastic containers for collection for metal testing.
