  产品规格

  Characteristics of Polystyrene Particles:

  Density: 1.05

  Refractive Index: 1.59

  Composition: Linear or crosslinked polystyrene

  Shape: Uniform microspheres

  Porosity: Nonporous

  Crosslinked polystyrene particles are stable in organic solvent, linear polystyrene is inert to alcohol and DMSO but soluble in DMF, acetone, acetonitrile, chloroform and methylene chloride

  Volume, Number and Surface Area VS. Particle Size

  Volume of Particle: V=(3.14/6) x D3 x10e-12 cm3/particles

  Number of Particle : N=(6W/3.14PD3)x 10e12 particles

  Surface Area of particles: A=(6W/PD) X 10e4 cm2

  W=Weight of polymer in gram

  P = Density of polymer (polystyrene =1.05)

  D = Diameter of particles in micrometer

  Total surface area of 1 ml of 5% w/v (50 mg) particle: A =2857/D cm2

  Total surface area of 20 ul of 0.25% w/v (50 ug) particle: A =2.857/D cm2
