| Polymer bound scavengers are an important tool for removal of excess reagents or side products in solution phase combinatorial chemistry. ScavengePore® is based on a macroporous high crosslinked polystyrene/DVB resin matrix. The permanent porosity provides a broad range of solvent compatibility. In contrast to standard gel type low crosslinked polystyrene/DVB resins swelling is reduced significant. To make filtration easy, the particle size is 200 – 400 micron. |
