For all of your magnetic separation experiments, these powerful racks sequester magnetic beads so that affinity ligands (antibodies, streptavidin or proprietary reagents for coupling nucleic acids) or rinse solutions can be added or decanted in assays. They utilize powerful magnets to quickly secure beads and offer exceptional quality and value compared to competing brands. The 96-well PCR plate model has 24 magnets that snugly hold the plate while attracting beads to the wall of the tubes and the flat bottom microplate model has magnets covering entire footprint to accept all standard micro-plates with any number of wells. All of the racks fit microplates following ANSI standards and are made of clear acrylic that allows unobstructed view of the tube contents.
