Very often when performing spin column purification, a small amount of wash buffer remains on the lip of the column after spinning it through the membrane. This can cause downstream problems with purity because the residual buffer can contain salts or ethanol that can end up in your eluted sample. Here we show you a quick and easy way to avoid this problem!

We hope that you have found this quick tip helpful!
