Why Do Isopropyl Alcohol Purity Grades Matter?
Selecting the correct grade of isopropyl alcohol can mean the difference between efficient processes and disaster. Using the right grade ensures compliant processes and low expenses. Using the wrong grade can lead to failed lab results, compliance issues and unnecessary costs.
Understanding Isopropyl Alcohol Grades
70% IPA Solution
70% IPA is the most popular choice for disinfection, with 70% alcohol and 30% water. The water slows down evaporation, allowing the IPA to stay on surfaces longer and killing more bacteria and viruses. It is cost-effective and easy to handle.
91% IPA Solution
91% IPA evaporates faster than 70% IPA, leaving almost no residue. This concentration is great for cleaning tasks that need quick drying, like wiping electronic parts or removing sticky labels.
99% IPA Solution
99% IPA is the highest purity and fastest to evaporate. Isopropyl alcohol is ideal for tasks that require minimal moisture, like cleaning sensitive electronics, laboratory work, or industrial processes that need high-purity solvents.
