MultiScreen® column loaders let you combine the cost savings of bulk media with the convenience of 96-well filtration plates. All 96 wells are loaded simultaneously and uniformly, eliminating the need for pipetting slurries or using prepacked columns. MultiScreen® accessories for radiometric assay detection include the MultiScreen® Punch Kit. After completing your multiwell radioactive assay, you can use the punch and disposable punch tips to simultaneously remove filters from eight wells of a MultiScreen® plate and distribute them into eight scintillation vials for detection. The patented punch tips remove each filter from its well separately, thereby eliminating the risk of cross-contamination and increasing reproducibility.
