Common use of Centrifugation time Clause in Contracts

Centrifugation time. Calculate the centrifugation time, tc, necessary to remove particles from solution greater than approximately 0.5 μm (5×10¥5 μm) equivalent diameter (which represents all particles except the fine clay fraction) using the fol- lowing equation: Equation 3 tc(min)=1.41×109 [log(R2/R1)]/N2 where: tc=centrifuge time in minutes R2=distance from centrifuge spindle to depo- sition surface of centrifuge R1=distance from spindle to surface of the sample N=number of revolutions of the centrifuge per minute.

Centrifugation time. Calculate the centrifugation time, tc, necessary to remove particles from solution greater than approximately 0.5 μm (5×10¥5 5 × 10¥5 μm) equivalent diameter (which represents all particles except the fine clay fraction) using the fol- lowing equationfollowing equa- tion: Equation 3 tc(min)=1.41×109 tc(min) = 1.41 × 109 [log(R2/R1)]/N2 where: tc=tc = centrifuge time in minutes R2=R2 = distance from centrifuge spindle to depo- sition dep- osition surface of centrifuge R1=R1 = distance from spindle to surface of the sample N=N = number of revolutions of the centrifuge per minute.
