Dip Coater

  1. We are constructing a dip coater in our laboratory. But because of the disparity between the lowest and highest speed it was suggeted that maybe the initial dipping could be performed by keeping the sample ( ie substrate to be dipped) stationary and elevating the solution until the sample is submerged , and then start the retracting of the sample the normal way ( ie by pullling it up).

    Basically the difference between this suggestion and common dipcoaters is that the sample is not actually "dipped" into the solvent, rather the solvent is raised until the sample is covered . Does this make a difference or not ?

    I'm sure it does. The coating on the sample wouldn't be subject to acceleration if you raise and lower the solution instead of the sample.
