Proteins are commonly concentrated using ultrafiltration. Product design of ultrafiltration devices for laboratory use consists of ultrafiltration membranes placed within housings specially designed to enable concentration through centrifugal, positive pressure, solvent adsorption and tangential flow separation methods.
The Sartolab® P20 & P20 Plus filtration devices are ready-to-use pressure filtration units for sterile filtration of media and aqueous solutions in batches ranging from 500 mL to 5 L.

Pipette filtration may also be used if small amounts of solid are noticed in NMR or GC samples, bey both instruments require analysis of liquids without suspended solids.
Separation technology is often an important element in laboratory-based research, development, analytics and diagnostics across all major applications and workflows. From the isolation of biologics in cell line development to sample preparation of waste water toptan kimyasal in epidemiology and the concentration of disease markers from human samples, Sartorius combines its wide range of application knowledge and innovative products to reduce specimen-to-report timelines and ensure efficient and easy filtration and purification processes.
Prefiltration may be carried out using a glass or cellulose based prefilter with a more porous filter matrix to enable a two-step Mekanik Karıştırıcı filtration process. Likewise, filter aids such kakım pharmaceutical-grade diatomaceous earth sevimli be applied directly within the cell culture to enable a prefiltration matrix layer on tamamen of the 0.2µm membrane layer to prevent blockages.
Gravity filtration usually utilizes the long stem funnel with olağan quarter-folded 11 cm diameter filter paper (Figure PAGENUM), when the filtration is done at room temperature or below. It is convenient to support the filter funnel by a utility clamp.
