Microspin columns (MSPE) are used for sample pretreatment as a substitute for SPE columns. The MSPE column consists of an internal microspin filter with a 0.22 micron membrane, above which a sorbent is placed, and an external centrifuge tube. The membrane can be made of nylon, PTFE (hydrophilic and hydrophobic), PVDF and acetylated cellulose. It is a simple and rapid sample preparation method that uses 2-in-1 membrane filtration and sorbent extraction in one step. MSPE columns are widely used in clinical biochemistry, toxicology, neuroimmunology and biotechnology. For more information, do not hesitate to contact us.
