Hudson Robotics has recently introduced the FilterPress™, a powerful alternative to vacuum nests, magnetic beads and centrifuges for the separation of a variety of materials.
The upper nest supports a wide range of filter/spin plates and SPE columns.
Any SBS format microplate can be used as a collection plate in the lower nest, and when empty, the nest acts as a waste trough.
Both the temperature and pressure of the air used to push fluids through the filter plates or columns are automatically controlled by software.
Both nests are accessible to the SOLO™ pipettor if placed by its side, and a Micro10x™ dispenser can be included to add a wide variety of wash and elution buffers to the filter plate or column in the upper nest.
The images below illustrate the different ways the FilterPress can be used:
Left: Without a collection plate and with a tube attached, the wash fluid can be passed through the filter plate, or column and be discarded.
Center: In this picture a collection plate has been added to the lower nest to collect intermediate or purified material.
Right: This image shows the FilterPress with both plates in position and positive pressure is beginning.
