COMPLETE QUESTIONS AND ANSWERS FULL
SOLUTION GRADED A+
◉ (Lab 1) Beaker. Answer: Size: 0-100s mL
Function: holds or heats large amounts of liquid
Accuracy: not accurate
◉ (Lab 1) Graduated cylinder. Answer: Size: 0-100s mL
Function: measures large volumes of liquid
Accuracy: more accurate than beakers
◉ (Lab 1) Mohr pipette. Answer: Size: 0-10 mL
Function: measures small volumes of liquids
Accuracy: very accurate
Notes: measurement stops before the end of the tip
◉ (Lab 1) Serological pipette. Answer: Size: 0-10 mL
Function: measures small volumes of liquids
Accuracy: very accurate
Notes: measurement continues to the end of the tip
, ◉ (Lab 1) Volumetric pipette. Answer: Size: 0-10 mL
Function: measures small volumes of liquids
Accuracy: HIGHLY accurate
Notes: dispenses a single volume with high accuracy and precision;
middle section are wider than either end of the pipette
◉ (Lab 1) Micropipette. Answer: Size: < 1 mL
Function: measures micro-liter quantities
Accuracy: very accurate
Notes: common sizes include P20, P200, and P1000 (20, 200, 1000
microliters, respectively); plunger has two stops, first for
withdrawing fluid and the second for delivering fluid
◉ (Lab 1) Spectrophotometer. Answer: Function: used to measure
the amount of light that is absorbed (0-2) by or transmitted (0-100)
through a sample, at particular wavelengths of light; can use to
obtain an absorption spectrum and standard curve
◉ (Lab 1) Beer-Lambert law. Answer: The absorbance of a solution
is directly proportional to the concentration of molecules in the
solution, and the mathematical relationship between them
