Product Announcement:
In the biomedical industry researchers are sometimes looking for cells having targeted specific gravities.? In order to locate these cells in test tubes it is useful to have colored marker beads which will show where the delineation between specific densities occurs.? Two microsphere products having densities of 1.065 g/cc and 1.075 g/cc were recently released.
These spheres are offered with density tolerances of ?0.005 g/cc enabling excellent stratification, and bright blue and red coloration for high visibility with the unaided eye.
R&D Quantities are in stock and ready to purchase in sizes from 10um to 600um, larger 1kg+ quantities can be made to order to existing specifications or made to your custom color and density requirements. For more information visit:? Blue Density Marker Beads 1.075g/cc,? Red Density Marker Beads 1.065g/cc.??? Additional densities of marker beads are also available in 1.01-1.10g/cc
