Jaw-dropping Mwco Ultrafiltration Spin Units, 12 Ml, Pack Of 24 Bonkers Deal: 85% Off [RfZD2BnH]

MWCO Ultrafiltration Spin Units

Experience the simplicity and efficiency of the MWCO Ultrafiltration Spin Units, designed for rapid desalting and concentration of proteins and macromolecules. These high-quality spin units offer an unparalleled 90% recovery rate, ensuring minimal loss of your valuable samples. With their advanced molecular weight cut-off (MWCO) polyethersulfone (PES) filter membrane, these units effectively retain macromolecules while filtrating salts and smaller molecules, making them ideal for a wide range of applications.

• Easy-to-use one-step procedure for desalting and concentrating
• High recovery rate of up to 90%

Product Specifications and Technical Details

The MWCO Ultrafiltration Spin Units come in four MWCO sizes – 10 K, 30 K, 50 K, and 100 K – to accommodate various molecular weight requirements. It is recommended to select an MWCO 1/2 to 1/3 smaller than the protein to be concentrated. These units feature a high flux PES membrane heat-sealed to the housing unit, ensuring faster filtration and less clogging. The retentate can be recovered at an excellent rate, thanks to the low protein/DNA binding properties of the PES filter. Additionally, the units are designed with low-binding materials, minimizing sample loss.

• Four MWCO sizes for versatile use
• High flux PES membrane for faster filtration
• Low-binding materials for high recovery rate

Applications and Benefits

The MWCO Ultrafiltration Spin Units are versatile tools for a wide range of applications, including protein concentration, desalting, and the removal of small contaminants. They are perfect for sample pre-treatment before HPLC analysis, deproteinization, and recovery of biomolecules from cell culture supernatants. With their rapid and efficient process, these units save time and reduce the need for multiple buffers, making them a valuable asset in any laboratory. Ideal for researchers, scientists, and professionals in the field, these units are a must-have for achieving optimal results.
