FAQ
Questions about the calculators
Laboratory math
Is this a calculator for human administration?
No. Outputs are concentration, molarity, and volume in mg, mL, mM, µg, and µL.
Why show both mg/mL and µg/µL?
They are the same number. Showing both makes the unit change explicit when a method is written in microliters.
Do you store what I type into a calculator?
No. The math runs in your browser. A form stores an email address only after you submit it with the consent box checked.
Which solvent should I use?
Use the solvent named by the supplier or the COA. The volume field does not select one.
Where do storage temperatures come from?
The storage page describes common laboratory setpoints and then tells you to follow the lot documents. It is not a stability specification.
