Sartorius VS15T42 VIVASPIN TURBO 15 100000 MWCO PES, 48/pk

The Sartorius VS15T42 is a centrifugal ultrafiltration device designed for concentrating and purifying biological samples such as proteins, antibodies, viruses, and nanoparticles. It is commonly used for sample preparation, buffer exchange, and desalting prior to analytical testing.

The 100 kDa molecular weight cut-off (MWCO) indicates that molecules larger than approximately 100,000 Daltons are retained, while smaller molecules pass through the membrane. This makes it ideal for separating large biomolecules like antibodies from smaller contaminants or buffers.

This unit is designed for sample volumes between approximately 4 mL and 15 mL, depending on the centrifuge rotor type. It can accommodate up to 15 mL in swing-bucket rotors and lower volumes in fixed-angle rotors, making it versatile for various lab setups.

The polyethersulfone (PES) membrane offers low protein binding, high flow rates, and broad chemical compatibility, which helps improve recovery and reduce sample loss. It is especially useful for sensitive biological samples that require high yield and minimal adsorption.

The device is engineered for high recovery rates typically exceeding 90–95%, thanks to its optimized design, twin membrane structure, and unique dead-stop pocket that allows nearly complete sample retrieval after centrifugation.
