Fractionation & Gradient Forming


This hybrid instrument performs both gradient forming and fractionating.

The Gradient Station™ is two distinct instruments combined into one compact, fully functional hybrid. One forms density gradients and the other fractionates them after centrifugation. The performance of these two elements,is identical to the original instruments, the Gradient Master™ and the Piston Gradient Fractionator™, which are described detailed on these sites.

Gradient Master™

Piston Gradient Fractionator™

    • Art.Nr: B153-002
      Base unit for generating linear density gradients and fractionation of centrifuged samples from the ultracentrifuge tube. The tube remains undamaged. The Gradient Station™ combines the Piston Gradient Fractionator™ and the Gradient Master™ in one device. All technical data, parts and accessories are identical to those of each instrument. Tube holders are required for each tube size. These must be purchased in addition to the basic device. Get in touch with us and we'll find the best configuration for your application.

    Gradient forming: in less than two minutes, you can produce 6 identical, linear gradients using a patented process we call tilted tube rotation. It is easy, fast and highly reproducible.

    Gradient fractionation: after spinning your sample in an ultracentrifuge, the fractionator breaks it down into fractions for further analysis, while measuring the UV/VIS profile during fractionation if desired. Other features include light scattering band visibility for documentation and individual band recovery, precise distance-based fractionation with 10µm resolution, and air and liquid injection into the tip of the piston to remove residual sample and clean the tubing between fractions and runs.

    For the Gradient Station different MagnaBase™ Tube Holders and PGF Tube Holders are available. Each tube size requires a seperate tube holder. Please choose a suitable tube holder for the respective tube size.
