Gelatin hydrogels for rheometer

  1. Apr 12, 2016 #1
    Hello, I am Marilli and I have a problem. :p
    I am trying to acquire some suitable samples for the rheometer measurements of gelatin hydrogels. The hydrogels are chemically crosslinked with EDC but after the crosslinking they remain sticky and therefore not suitable samples can be punzed out. Has anyone an idea?
