You notice that your micropipette is inconsistently aspirating more or less liquid than what it is set to aspirate. What type of error is this?

Using the standard curve below, what is the concentration of a sample that gives an absorbance of 0.5 when 5 microliters of sample are assayed?

Tris is a commonly used buffer between pH 7.5-9.0. Why is it not used above or below this range?

Which of the following should be considered for authorship on a paper?

A well-designed study may initially show statistically significant results, but follow-up studies do not confirm these results and show no effect. This is an example of

A protein has an absorbance of 0.65, and 3 tryptophans (ε = 5500) and 4 tyrosines (ε = 1490). What is its concentration?

What would the transmittance of a sample be if the absorbance was 0.1?

You have a 1 M Tris buffer at pH 8. If you dilute this solution to 0.01 mM for an experiment,

How do you prepare 465 ml of 65% v/v ethanol (Mw = 46 g/mol)?
