NanoDrop Eight User Guide 83
• Use
to ensure proper liquid column formation.
• Use new tip for each blank and sample aliquot.
• Use new aliquot of sample for each measurement.
• When the measurement is complete, open the sampling arm and wipe the
samples from both the upper and lower pedestals using a soft laboratory wipe.
If solvents are used, make sure they are compatible with the pedestals. (see
“Compatible Solvents” in
).
Recommended sample volumes
To measure a micro-volume sample
Application
Sample Volume
Nucleic acid (aqueous solution)
1 µL
a
a
Use 2 µL for samples that contain materials that may reduce surface tension such as a surfactant.
Purified protein
2 µL
Other protein applications such as Bradford or BCA
2 µL
Microbial cell suspensions
2 µL
NOTICE
• Do not use a squirt or spray bottle on or near the instrument as liquids will
flow into the instrument and may cause permanent damage.
• Do not use hydrofluoric acid (HF) on the pedestals. Fluoride ions will
permanently damage the quartz fiber optic cables.
