WebMay 20, 2024 · Scaffold Density. Density measurements of the decellularized scaffolds were made using a 10 mL pycnometer (Bomex, Bejing, China). Room temperature DI H 2 O was used as the medium for gravimetric displacement. The volume of the pycnometer was calculated by dividing the total mass of water that it could contain by the density of water.
