Filter Functions As Screening Tool
EMD Millipore, the Life Science division of Merck KGaA of Germany, has released an addition of the Millistak+ µPod filter to its product portfolio of disposable depth filter systems. The smaller, 23 cm2 filter is designed for use as a process development screening tool for depth filter selection and optimization.
Available in four media categories representing 26 media grades, the filter enables users to connect multiple devices in parallel or series to rapidly screen combinations of media. They are suited for primary and secondary clarification applications such as cell cultures, yeast and E. coli lysates post centrifuge, E. coli refolds, media, vaccines, plasma proteins and sera.
In addition, the Millistak+ Pod filters incorporate multiple graded-density layers and adsorptive, positively charged filter media to accommodate applications from lab to pilot to process scale. The pod format offers greater flexibility because of its enclosed and fully disposable design.
