WaterSep has developed a unique line of single-use, glycerin free(GF), low extractables hollow fiber cartridges, that significantly reduce the cost of ownership and eliminate pre-rinsing of the membrane. WaterSep’s single-use hollow fiber cartridges – The Green Line – are manufactured in a completely glycerin free, environmentally friendly process, hence no pre-rinsing of the membrane is required. This saves valuable time and large consumption of high purity water. The Green Line is available in WaterSep’s well accepted hollow fiber format for laboratory and process applications.

Whether you have diluted protein solutions, a cell clarification application or a viscous process stream WaterSep can offer a membrane with the optimum cut-off, the right fiber diameter and a hollow fiber cartridge with the perfect length and surface area.

0.5 mm: Ideal for processing clean, low viscosity solutions including concentration and diafiltration of proteins and enzymes.

1.0 mm: Ideal for processing particle laden, viscous solutions, including concentration and diafiltration of cell broths, cell debris and vaccines.

2.0 mm: Ideal for processing large particle laden and very viscous solutions, including concentration and diafiltration of highly concentrated cell broth.

With 0.5 mm, 1.0 mm and 2.0 mm ID hollow fiber cartridges, WaterSep can address most of your application needs.

We also apply our extensive membrane and application experience to develop dedicated products for custom applications in biopharm and medical markets.

With 9 different membrane pore sizes, 3 hollow fiber diameters and 9 cartridge configurations, WaterSep wants to become your dedicated source for membrane separation applications.

WaterSep introduces 3 more membrane cut-offs and 0.1 µm micro filter!
WaterSep has added a 30K, 300K and a 500K MWCO to its product line.

• The 30K is optimized for monoclonal antibody concentration and diafiltration.
• 300K is our dedicated vaccine membrane, designed for concentration and purification in vaccine processes. The open flow format of hollow fiber is ideal for large fragile molecules like vaccines.
• The 500K membrane is our tightest cell separation membrane and is well suited for E.Coli lysate clarification, when a 750K or 0.1µm doesn’t produce a particle free permeate.

Our 0.1 µm hollow fiber cartridge is particularly well suited for mammalian cell clarification during monoclonal antibody production. The membrane retains the cells, while passing the antibody > 99%. The 0.1 µm membrane is also ideal for most clarification applications in the food and beverage industry.

All 4 membranes are available in the Explorer, Investigator and the Producer series.
