  • Ultrafiltration Centrifuge Tube: What Every Researcher Ne | OBObio
    Ultrafiltration centrifuge tubes excel in protein concentration, buffer exchange, desalting, and DNA RNA purification applications These devices are particularly valuable for HPLC sample preparation, antibody purification, and removing unwanted molecules from biological samples
  • How to Use Centrifugal Filter Units? - cobetter. com
    This article discusses the differences between ultrafiltration and microfiltration, and provides guidance on how to select and use centrifugal filters, which can serve as a reference for researchers and professionals
  • Small Tips to Keep in Mind When Using Ultrafiltration Tubes
    This is a critical step to ensure smooth experiments, protect the ultrafiltration tube (which is expensive!), and protect your sample
  • Centrifugal Concentrators | Sartorius
    Sartorius leads the industry in laboratory ultrafiltration, with the most comprehensive selection of centrifugal ultrafilters, including options for normal flow filtration or our pioneering formats that utilize tangential flow filtration (TFF)
  • How to Collect and Handle Filtrate from an Ultrafiltration Centrifugal Tube
    In ultrafiltration, the target fraction is sometimes the filtrate (also called the flow-through or permeate) collected in the outer tube, which contains molecules that have passed through the
  • Protein Sample Ultrafiltration - MilliporeSigma
    Still not sure how ultrafiltration could be used in your lab? Check out our ultrafiltration protocols for protein sample preparation to see how you could speed up and improve your sample preparation
  • Amicon Ultra-4 Centrifugal Filter Devices - MilliporeSigma
    Subtract weight of empty device tubes to calculate weights of starting material, filtrate, and concentrate Assay the starting material, filtrate, and concentrate to determine solute concentration Calculate recoveries using the weight volume data and the measured concentrations as follows:
  • Ultrafiltration Devices | Sartorius
    Simply prefilling the permeate tube with water or buffer before starting ultrafiltration is sufficient to stop ultrafiltration earlier This technique is also useful when you need to concentrate multiple samples to the same final volume in a single run with a fixed spin time
  • Centrifugal Filter – Membrane Solutions
    The UF tube uses PES membrane material, which has low protein adsorption However, for some hydrophobic or non-polar proteins, non-specific adsorption to the membrane may be enhanced
  • Centrifugal devices - Cytiva
    It is important to recognize that retention of a molecule by an ultrafiltration membrane is determined by a variety of factors, among which its molecular weight serves only as a general indicator
