In total, I test 7-10 samples. I want to compare the surface tension measurements. annalisameinhart https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826352 2022-04-28 08:51:12 UTC https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826352 Finally, I evaluate all measurements using the program. annalisameinhart https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826353 2022-04-28 08:51:12 UTC https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826353 To finish, I save the files and put the results in a report. annalisameinhart https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826354 2022-04-28 08:51:12 UTC https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826354 To prepare the samples, I need holders in different sizes, a plastic mat, gloves. Sometimes I need ethanol and Q-tips to clean the components. annalisameinhart https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826355 2022-04-28 08:51:12 UTC https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826355 The tension is read by measuring the angle a drop of water and diiomethane has-- to the surface. (2 drops of liquid) These liquids are different: one polarizes and the other disperses more. The program calculates the results of the two angles. annalisameinhart https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826357 2022-04-28 08:51:12 UTC https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826357 Make sure that you use gloves the whole time. annalisameinhart https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826358 2022-04-28 08:51:12 UTC https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826358 Don't forget to clean your workspace after your work and to also wash your hands. annalisameinhart https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826359 2022-04-28 08:51:12 UTC https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826359 From my experience, it is important to check the measurement after the reading because it sometimes can not read exactly and the result is not good. Then you have to repeat the measurement. annalisameinhart https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826360 2022-04-28 08:51:12 UTC https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826360 It is important.... annalisameinhart https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826362 2022-04-28 08:51:12 UTC https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161826362 SURFACE TENSION TEST annalisameinhart https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161828950 2022-04-28 08:53:08 UTC https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2161828950 When you don't have any liquid coming out, make sure you refill the missing liquid. annalisameinhart https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2168170982 2022-05-03 12:01:17 UTC https://padlet.com/annalisameinhart/6n4v3flrscztwrdv/wish/2168170982
