You fill the small one, pull it off and let the vacuum equalize, shake the little bottle up and then run the small bottle contents back in to the big bottle and shake it up and then you are ready to go. It comes with a different style of transfer needle that lets you bleed the suction off and then squeeze the big bottle to pull the contents of the little bottle back in.

It sounded like the other lepto strains that are most common in our vaccines are actually European strains we don't even have here.
