Industrial Ultrafiltration Spiral-Wound Element:
XT(PES 1kDa)
Synder Filtration’s Ultrafiltration Elements offer an optimal combination of both flux and rejection in a comprehensive range of MWCO’s. Contact us today to learn more about our complete line of membrane products and services.
XT is the tightest PES-based ultrafiltration membrane that Synder currently offers, with a molecular weight cut-off of 1kDa. Given the smaller pore size, this membrane excels in the separation performance of proteins, bacteria, and large particulates, while allowing sugars and salts to pass through the membrane. Common applications include color removal, antibiotic concentration, protein concentration, and polypeptide concentration.
INDUSTRIAL SERIES BENEFITS
- Widest range of UF MWCO’s available
- Good resistance to pH and temperature
- High resistance to fouling
- Customizable dimensions for unique housings
COMMON APPLICATIONS
- Color removal
- Antibiotic concentration
- Protein & polypeptide concentration

TECHNICAL NOTES
For element sizes not listed, please call or email Synder Filtration for details. We can design an element to fit your exact needs – just specify the element outer diameter (OD) or vessel/housing inner diameter (ID), element inner diameter (ID), and length. Elements are also available with or without a controlled bypass tail. Additional feed spacers are also available. Trials should be conducted to determine optimal application conditions.
