Objectives

1. Perform pressure tests on all prepared hydrogels using a bent pipette.
2. Run fluorescence on the samples obtained from the pressure tests.

Pressure tests

• Pressure tests were performed on all hydrogels prepared with Rhodamine 6G added.
• After the sheer pressure test conducted on 2013/02/22, it was determined that a bent pipette and an unmodified pipette would be used to conduct the pressure tests. Each hydrogel will have at least two pressure tests conducted with the hydrogel: one with a bent pipette and the other with an unmodified pipette.
• All pressure tests were conducted following the general protocol described on 2013/02/22.
