The Gradient Master


     This is BioComp's premier gradient forming instrument.
  In as little as 40 sec, you can produce 6 identical, linear gradients using a patented process we call tilted tube rotation. The process involves layering the two end point solutions (i.e. 5% and 30% sucrose) directly in the centrifuge tube, capping it and placing it in a special tube holder with a magnetic base (MagnaBase™) that adheres to a steep plate on the instrument. Two keystrokes later, the Gradient Master takes over and tilts the tube to the proper angle, rotates it for a designated time and returns it to its original vertical position.
  The introduction of the model 107 is the latest step in the evolution of this remarkable instrument. It has several new features that distinguish it from previous models. First, its memory contains all the run parameters for all the many different gradients we have developed for our customers. To see the list, select the rotor (ie SW41) you are using and then scroll through a list of the gradients organized by % and solute. To simplify things further, the “LAST” key on the keyboard recalls the last gradient run, so 2 keystrokes are all that are needed to duplicate a run.
  Second, the unit is now internet programmable. You can download new software yourself as upgrades become available. The gradient catalog is also upgradable so users can benefit from our ever-expanding set of run parameters. Solutes used so far include sucrose, glycerol, Optiprep®, Nycodenz®, Ficoll®, Percoll®, Metrizamide, Renografin®, NaCl, CsCl, NaAc, KCl. Like the old saying, the Gradient Master has never met a solute it didn’t like.
  The Gradient Master is also a patented, intelligent roller blot device that can perform all the blocking, blotting and reaction steps with unerring accuracy and reproducibility. Using our patented MagnaBase™ bottles which come in a variety of sizes to fit every blot without overlap, you can reduce your reagent use by 90% while obtaining superb blots.
  If you are serious about your gradient work, there is no competition for the Gradient Master. In nearly a thousand labs around the world for 18 years, it has become the gradient former of choice because of its simplicity, incredible speed and durability.
