Hi [...],
I fear it [...] be trial and error.
In my case, I bought a 10ml oral syringe and a 100ml graduated cylinder. I measured out 100ml with the syringe into the cylinder and the water level ended up quite a bit above the 100ml mark.
I could have bought another cylinder and another looking for one that measured exactly what the 10ml syringe was measuring but I decided not to. I work with a lot of lab equipment (10% milk bottles, different sized beakers, cylinders etc.) in my job because of the testing we do on the product we make here at the [...]where I work and in my experience, no two measure exactly the same. It [...] [...] the nature of the way they are made and marked.
Because of this, I decided to stick with [...] measuring out my suspension mix and my dose with the syringe. Whether or not the cylinder or the syringe was measuring the most accurately becomes immaterial because I am measuring with the same instrument each and every time mixing my suspension and taking my dose.
You could get lucky and find one that measures the same, [...] check it first to be sure.
