PKU odor
mousy/ musty urine odor
A _ operates by moving the piston in the pipet tip or
barrel, much like a hypodermic needle.
It does not require a different tip for
each use.
Because of carry over concerns, rinsing and blotting between samples
may be required.

is the unit of measure for the wavelength of radiant energy (light).
NANOMETER
T or F
Wavelength is directly proportional to the amount of energy. The longer the wavelength, the lower the energy; the shorter the wavelength, the higher the energy.
F
inversely
