I. Product introduction

PES membrane package provides various specifications of membrane pore size; Our proprietary membrane surface grafting technology greatly improves the hydrophilicity and biocompatibility of the membrane, and greatly reduces the shortcomings of easy adsorption of proteins on the membrane. It is specially designed for biotechnology and pharmaceutical industry and can be widely used to separate the following substances from liquids: mammalian cells, Clostridium, yeast, salmonella, mycoplasma, etc.

Second, the application field

The membrane package made of PES membrane is specially designed for tangential flow filtration in R&D, pilot and production scale, and is mainly used in clinical, life science and biopharmaceutical fields, such as:

▼ Separation and purification of blood products

▼ Concentration and washing of vaccines and coupled products

▼ Only remove pyrogen, such as pyrogen removal of traditional Chinese medicine injection.

▼ Concentration, purification and separation of protein, polypeptide, polysaccharide, virus, accounting and antibody.

▼ Separation of cells/cell fragments (cell collection, cell removal)

▼ Replacement of buffer solution, such as the change of buffer solution system before and after chromatography.
