Frequently Asked Questions

What is the dilution equation?
The dilution equation is C1V1 = C2V2, where C1 and V1 are the initial concentration and volume, and C2 and V2 are the final concentration and volume. This works for any concentration unit as long as both sides use the same unit.
What is a serial dilution?
A serial dilution is a stepwise dilution of a solution. Each step dilutes by the same factor. For example, three 1:10 serial dilutions give a total dilution of 1:1000. Used in microbiology, ELISA assays, and antibiotic sensitivity testing.
How do I calculate dilution factor?
Dilution factor = final volume / initial volume, or equivalently, initial concentration / final concentration. A 1:10 dilution means 1 part sample + 9 parts diluent = 10 parts total.
