VP 772F6

     
 


The VP 772F6 was designed as a magnetic separation stand for eight 1.5 ml or 2.0 ml micro centrifuge tubes. The stand has 8 stacks of two 10 mm diameter by 6 mm tall NdFeB magnets (52 MGO) positioned to capture magnetic beads to the bottom of the tubes.

 
 
         

 
  50ml Tubes

     
 


VP 772F1M & VP 772F1R

     
 
This magnetic bead separation system for 50 ml conical test tubes consists of 2 parts.  The VP 772F1M is a magnetic base which set on a base with the same dimensions as a microplate (127.76mm by 85.48 mm) holds four 48 MGO NdFeB magnets that are 25.4 mm cubes.  The VP 772F1R is a rack holding eight 50 ml conical test tubes which can be manually or robotically placed over the magnetic base and the magnetic beads in the test tubes are rapidly separated by the large and power magnetic field generated by the VP 772F1M.

The photo on the right illustrates the two parts mated together and the photo below it illustrates how they perfectly fit together and hold the test tubes close to the magnets for rapid separation of the beads.  Note that we have machined slots in the tube rack so you can see the tubes and when the beads have been separated.

The key to our success is that we use very large magnets with high energy 48 MGO or higher.

The photo to right illustrates a tube with suspended  Magnasil beads (Promega) and the photo just below it was taken just 20 seconds later.   The same test performed on a similar Promega separation system using much thinner and weaker magnets required twice the time to separate the beads.

   
 

Using our VP 710 Series Stirrers, with the VP 772FN-25-105MB, you can easily resuspend your beads.

 
   
 
 
   
 



VP 772FB-1

     
   Single magnetic separation stand made from HDPE (High Density Poly Ethylene 63.5mm diameter and 61mm tall) for 50ml centrifuge tubes with one magnetic cube (25.4mm on a side). This very large magnetic cube is made from a very high energy rare earth magnet (48 MGO NdFeB). The design of the VP 772FB-1 was constructed to reduce the distance between the magnet and the tube to zero, thus maximizing the holding power of the magnet to the beads. This magnet produces a very large and very powerful magnetic field which will capture your magnetic beads in just a few seconds and will tightly hold the beads to the tube wall through the most rigorous washing procedure.


If speed of separation and vigorous washing are important in your application this the magnetic separation stand for you.

 





 
  The VP 772FB-1 separation stands can be linked together via the magnetic force of the magnets to form a row of separation stands of any length.  

 
  Depending on your assay and the liquid volume of your assay, you may want the location of the magnetically captured beads in the tube to be lowered. This may be important if you are using low volumes of incubation or wash buffers. You can lower the capture level by simply placing quarters in the bottom of the separation stand and raise the tube up. The more quarters you put in, the lower the magnetically captured beads will be held in the tube.


We could make a custom insert and charge you a lot of money for it but it wouldn’t work any better than a stack of quarters or other coins of similar diameter.

 



 
 

VP 772FB-1A

     
  The VP 772FB-1A is a clear Acrylic cylinder 29.22mm in diameter and 51.82mm long with a 16.44mm diameter hole drilled so it is tangent to the magnet edge and has a 16.38mm wide opening to the magnet. The VP 772FB-1A was designed as an adaptor to fit inside a VP 772FB-1 and allows the use of test tubes that have diameter smaller than 16.44 mm (15 ml conical centrifuge tubes, 13 ml standard plastic test tubes and 10 ml glass screw cap test tubes). This greatly increases the versatility of the VP 772FB-1 magnetic separation stand.

The very large magnetic cube of the VP 772FB-1 is made from a very high energy rare earth magnet (48 MGO NdFeB). The design of the VP 772FB-1A was constructed to reduce the distance between the magnet and the tube to zero, thus maximizing the holding power of the magnet to the beads. This magnet produces a very large and very powerful magnetic field which will capture your magnetic beads in just a few seconds and will tightly hold the beads to the tube wall through the most rigorous washing procedure.

If speed of separation and vigorous washing are important in your application this is the magnetic separation stand for you.


   
 

Top View of the VP 772FB-1A is seen in the photo to the right. Note how the eccentric placement of the hole through the Acrylic rod places the tube against the magnet. An added benefit of the Acrylic cylinder is that it functions as a magnification lens to help visualize the beads.

 



 
 

Depending on your assay and the liquid volume of your assay, you may want the height of the magnetically captured beads in the tube to be lowered. You can do this by simply placing quarters in the bottom of the Separation Stand under the VP 772FB-1A. The more quarters you put in, the lower the magnetically captured beads will be held in the tube. This may be important if you are using low volumes of incubation or wash buffers.

A 13 ml test tube is shown with a VP 772FB-1 and a VP 772FB-1A and a stack of quarters in the photo to the right.

   


  VP 772FB-1B & VP 772FB-1C

 
 

The VP 772FB-1B and VP 772FB-1C are magnetic bead separation inserts that are used with the VP 772FB-1 for magnetic bead separation at low volumes in 50ml tubes and 15ml tubes.  The insert will pull the magnetic beads to the conical side of the tubes for low volume washing and elution.
