what is the dilution factor if I place a 10 micro litre inoculating loop into 10ml ofWatch
What is the dilution factor/ratio/ any other information ill need to know.
and will this be called 10^-1 or what?
The dilution factor is 1000, as you're going between millilitres and microlitres. Remember 10 millilitres is equal to 10000 microlitres (x1000).
If this continued as a serial dilution, it would go 10^-3, 10^-6, 10^-9 etc..... since you're diluting by 1000-fold every time.
