Centrifuge Tubes (ASTM) for sedimentation control

Specifications

          Pear-shaped centrifugal tube having a graduated stem. Used for ascertaining the magnetic particles concentration in the suspension.
         After a settling period (30 minutes for water-based carrier and 60 minutes for oilbased carrier) with the exact concentration a specified graduation mark has to be reached (acceptable ranges of settled particles volume is 0.1 to 0.4 ml / 100 ml for fluorescent particles and 1.2 to 2.4 ml /100 ml for visible particles according to ASTM E-1444-01).
