# What is the elastic modulus of the high concentration/different dilution VitroGels?

For VitroGel High Concentration hydrogels, the elastic modulus (G’) can be adjusted from 10 to 4,000 Pa by changing the hydrogel concentration with the VitroGel Dilution Solution. The G’ is about 4000 Pa at 1:0 dilution, 1200-2000 Pa at 1:1 dilution, 600-1000 Pa at 1:2 dilution, 200–500 Pa at 1:3 dilution, and < 500 Pa at dilution higher than 1:3.
