About the Spectrophotometer
The Thermo Scientific™ NanoDrop™ OneCis a compact, stand-alone
UV-Visible spectrophotometer developed for micro-volume analysis of a wide variety
of analytes. The patented sample retention system enables the measurement of
highly concentrated samples without the need for dilutions.
The NanoDrop One system comes with preloaded software and a touchscreen
display. NanoDrop One PC Control software can be installed on a local PC and used
to control the instrument and view data. The instrument can be connected to an
optional printer with a USB cable or to a remote printer through an Ethernet
connection or wireless network.
Note Locate the instrument away from air vents and exhaust fans to minimize
evaporation
Note Before operating a NanoDrop One instrument, please read the safety and
operating precautions and then follow their recommendations when using the
instrument.

Cuvette Holder
The NanoDrop OneCincludes a cuvette holder for measuring dilute samples,
colorimetric assays, cell cultures and kinetic studies. The cuvette system has these
features:
• extended lower detection limits
• 37 °C heater option for temperature-sensitive samples and analyses
• micro-stirring option to ensure sample homogeneity and support kinetic studies
For details, see Measure a Sample using a Cuvette.
USB-A port
One USB-A port is located on the front of the instrument and two more USB-A ports
are located on instrument back panel.

DYMO™ LabelWriter™ 450 USB Label Printer
Prints two 5/16-in x 4-in self-adhesive labels for transferring sample data directly into
laboratory notebooks or posting on bulletin boards. The software allows printing of
data from each sample measurement or from a group of samples logged and
measured together.
The printer connects to the instrument (front or back) via a USB cable (included).
PR-1 Pedestal Reconditioning Kit
PV-1 Performance Verification Solution
Liquid photometric standard used to check instrument performance. For more
information, see Performance Verification.
Specially formulated conditioning compound
that can be applied to the pedestals to restore
them to a hydrophobic state (required to
achieve adequate surface tension for accurate
sample measurements). The kit includes
conditioning compound and applicators. For
more information, see Reconditioning the
Pedestals.
