I was drawing from my 10ml vial today and i pressed the plunger to get some air out of the syringe and it appeared as if there was a streaky glob type thingy in the vial . It went away seconds later but it just looked a little odd. Is this just what oil looks like when its quickly shot back into the vial ?
Not sure i explained that well but im not sure what else to say.
thxs.
