OBJECTIVES

  • Continue fluorescence detection through pressure testing analysis of hydrogel samples (new modifications & better results)

Straight Pipette: Hydrogel Pressure Samples Tested 3

RECALL HYDROGEL PRESSURE TESTING PROTOCOL ON 2/20/13 & FLUORESCENCE ANALYSIS PROCEDURES ON 2/13/13

Notes

  • The pipettes that provided the best fluorescence results for each sample were both the straight plastic and 90° angle bent pipettes.
  • All samples run maintained a composition incorporating Rhodamine 6G dye
  • All samples on 3/01/13 were tested using the straight pipette. (See figure listed below)
