What is microstir?



What is microstir?..

Answer / eugene

Microstir is a low volume mixer like 10 microlitres. The
elements can be microscopic stirrer bars, piezoelectric
membranes, or gas bubbles.

When used microscopic stirring bars in a laboratory
setting, these plastic-coated magnetic bars almost
eliminate the contamination of the mixing fluids
with 'typical' metal parts. For example, when mixing
hydrochloric acid with nitric acid, a polymer mixer is
typically preferred due to the high number of metals which
react to this blend. These mixers can have variable mixing
speeds from 10 rpm to 10,000 rpm.

Find the value of x. (b) The probabilities of finding a particle around points A, B and C in the wavefunction y = f(x) are P(A), P(B) and P(C) respectively. Coordinates are A (3,5), B (4,-10) and C (6,7). Arrange P(A), P(B) and P(C) in term of a < b < c, when | y-coordinate | signifies the probability.
