# Does VitroGel have viscoelastic properties?

Yes, all VitroGel hydrogels are tested with a dynamic rheometer for viscoelastic properties. 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.
