FILTROSPIN™ 20 Small scale filtration
8 Mar 2022In order to evaluate the most suitable and optimized production process, small-scale trials are the key factor to start with. With the help of laboratory-scale trials, errors and other issues can be identified early in the development process and responded to accordingly. In this application note, the quick and easy way to identify a suitable depth filter sheet for a respective product to be filtered before purchasing the large and expensive filtration equipment is described.

FiltrationFiltration and microfiltration are used to separate solids, particulates or large molecules from fluids (liquid or gases) in order to purify the filtrate. Explore a range of filter formats, including filter paper, plates and membranes for your separation needs. While larger particulates may be separated by gravity filtration, smaller particulates may require additional force for timely separation. Microfiltration equipment includes vacuum filters, as well as positive pressure, crossflow and centrifugal filtration devices.

Centrifuges come in three sizes: microcentrifuges, benchtop and floor-standing centrifuges, depending on the volume and number of samples that require separation. When choosing a centrifuge, consider its maximum separation power indicated by its relative centrifugal force (RCF) value. Low force centrifuges reach a maximum RCF of 8,000 g, high-force centrifuges can reach maximum RCF values of 80,000 g. For extremely high forces, consider ultracentrifuges (up to 800,000 g). Refrigerated and vacuum centrifuges also known as concentrators are available for more specialized applications. A range of volumes are available for centrifuge tubes and microfuge tubes, depending on sample sizes.

The most well known example of a biopharmaceutical product, and the first to be approved for therapeutic use, was recombinant human insulin.Ultrafiltration
