Hope I am posting in the correct section. Can 95% purity n-Hexane be mixed with 99% purity n-Hexane without any adverse effects? Don't really care about the purity levels above 95% as it will only be used for testing process piping in a system. After the test, they will go in to a glass container and remain their until it is needed to test the next system. I have 5 liter quantities of each. I need 10 liters for a test but 95% hexane has a longer lead time and I don't have the time.
