Tearlab osmolarity system

TearLab Osmolarity System measures the osmolarity of tears using nanoliter (nL) volumes of tear fluid collected directly from the eyelid margin. The system consists of two battery-operated osmolarity test pens, the countertop unit, and a supply of single-use test cards. The countertop unit analyzes the tear fluid samples and displays the results on an LCD screen. The test cards come in individual foil pouches and one is loaded onto each test pen.
