so i have this IO cal. test kit. it comes with 2 vials. one big, one small. you are supposed to use the small one to retrieve the correct amt. of water to put into the larger vial. i lost the smaller vial. i was wondering if anyone uses this same kit and if there were some way to measure the correct amt. of water i need for this test, perhaps in ml or something. i would really appreciate it if some one could do this for me. thanks.
