3M Zeta Plus DEL

3M™ Zeta Plus DEL Filters

Zeta Plus™ DEL Series is a family of depth filter media which incorporates lipid-specific adsorbents for selective removal of lipids, surfactants and biological hydrophobes from human blood plasma, serum-based products, recombinant proteins and other biological fluids.
Two different DEL media types provide a range of lipid removal capacity and functionality: DELI and DELP.

Features / Benefits

• Provides effective protection and extended life for chromatography columns and reusable membranes.
• Highly scaleable.
• Flexible options for all flow and batch volume requirements.
• Easily cleanable, no external contamination, offers rapid assembly and take down.
• Safe for critical pharmaceutical, bioprocessing and biological applications.
• Components meet USP Class VI Biological Safety Tests and requirements of CFR 21.

Operating Conditions

• Maximum Operating Temperature 82° C (180° F)
• Recommended Flux 1.2 - 12 lpm/m²

Typical Applications

• Lipid removal from human blood plasma proteins such as albumin, coagulation factors, fibrinogen, and immunoglobulins
• Provide protection, enhanced performance and extended life for chromatographic columns and ultrafilters
• Removal of residual lipids from serum, fermentation broths and cell culture fluids
• Removal of detergents and surfactants from biologicals
• Separation of hydrophobic bioprocess contaminants from aqueous solutions
