Surface Tension

The NanoDrop One

C

spectrophotometer uses surface

tension to hold a small volume of sample between two
pedestals. The patented sample retention system enables
the measurement of highly concentrated samples
without the need for dilutions.

A fiber optic cable embedded in the upper pedestal leads
to a xenon light source. A second cable embedded in the
lower pedestal leads to a detector. When the instrument
arm is down, the sample forms a liquid column,
essentially bridging the gap between the two fiber optic
cables.
