Abstract: Borosilicate glass (G) and commercial poly(methyl methacrylate) (PMM) surfaces were examined at pH 7, monovalent ionic strength 0.14 and 22 degrees C. Thrombin concentrations ranged from 6 X 10(-9) to 5.2 X 10(-8)M. Decreases in thrombin concentration in 10 ml vessles were determined by clotting time assay. Adsorption to PMM vessels is small. These were examined to establish the validity of the method. For G-vessels, the terminations of initial rapid decreases, associated with adsorption equilibrium, are accou…
