More Tensiometer!!

Just because I use exclamation points does not mean its a bad thing, its actually very interesting. Today was all tensiometer since we need to get data for each surfactant concentration and several readings for each. The 0.03% solution results from yesterday are 59, 60, and 61. We are satisfied that this surface tension is around 60. We then empty the 0.03% solution from the syringe, and rinse the syringe three times using the 0.06% solution. We then set up the tensiometer to take three readings on this solution, and the surface tension of the 0.06% solution was determined to be 50, 51.5, and 51, so the average surface tension is 51 for 0.06% surfactant solution. We will continue with the remaining solutions tomorrow.
