The different vessel materials as well as the liquids are leading to different liquid profiles that are independent from the operation conditions (r0, ω).
As can be seen different surface tensions, due to the type of fluid or a change of the sample temperature, have a significant impact on the liquid profile. An increased surface tension value results in a lower profile. For different fluids (Aqua dest. and DMSO) with identical filling volumes and operation conditions the maximum fluid height can differs more than 200%.
On the other side for identical liquid properties and filling volumes, the change of the contact angle due to different construction materials, which are commonly used for microplates (PS and PP), leads only to a change of less than 10% of the maximum fluid height.
