Description
Guidling UF cassettes have been developed and manufactured to give consistent performance. Guidling UF cassettes are available for laboratory, development, pilot, and production-scale TFF applications.
UF is a method of separating very small particles and soluble molecules from solutions. This separation is mainly based on the size of particles or molecules , but the permeability of the membrane material will also be affected by the chemical, molecular and charge characteristics. of the sample. Ultrafiltration is usually used to separate molecules with a size difference of more than 3-5 times, and is not suitable for molecules of similar size.

Typical Applications
Clarification: such as separate cell /cell debris
Concentration: protein concentration
Desalination: desalting of nucleic acid, nano microspheres and peptides
Buffer replacement: buffer system change before and after chromatography
Depyrogenation: pyrogen removal of culture medium and TCM injection

The UF Cassettes Advantage
Superior new materials of construction and improved cassette design increase process safety, reliability, reproducibility, and productivity:

●The feed and permeate screen material for UF cassettes is made from polypropylene, which is highly resistant to sodium hydroxide.

●Larger feed and permeate ports provide lower pressure drops.

●The UF cassettes have been designed to provide maximum mass transfer through the membrane, resulting in faster processing times or reduced area installations compared to existing similar cassette formats.
