Idea Exchange: A better method to obtain total protein concentrations
Our technicians hated blowing serum out of hematocrit tubes onto refractometers because their lips often touched the tubes. Our solution: Use the droppers from ½-oz amber dropper bottles (from the pharmacy) to blow the serum out of the hematocrit tube and onto the refractometer. It's sanitary and easy!
