PrepTip

PrepTip is a revolutionary new method for cleaning and concentrating proteins and other biological samples for further instrumental analysis. PrepTip's unique, patented feature is that the interior walls of the tip are coated with the sample-binding material.

This interior coating technology makes PrepTip the only such product on the market, providing both speed and reliability. Since the tip opening is not plugged by the interior coating process, the sample can flow freely through the opening without back pressure. PrepTip can be used to clean or concentrate any biological sample since the interior walls of the tip can be coated with your choice of binding media. Different binding materials are offered by Harvard Apparatus.

Due to its unique features, sample preparation with PrepTip is very fast, simple and highly effective. PrepTip is well suited for a range of applications including mass spectrometry, HPLC and automated sample preparation methods.
