Thermo Scientific Thermo Scientific μDrop and μDrop Duo Plates User Manual 1

Introduction to the μDrop and μDrop Duo Plates

Introduction

Thermo Scientific™ μDrop™ and μDrop™ Duo Plates are tools designed for quick and easy absorbance

measurement of low sample volumes (2–10 μl) and cuvettes with the following instruments:

• Thermo Scientific™ Multiskan™ SkyHigh

• Thermo Scientific™ Multiskan™ Sky

• Thermo Scientific™ Multiskan™ GO

• Thermo Scientific™ Varioskan™ LUX

The μDrop and μDrop Duo Plates are typically used for photometric DNA, RNA and protein

quantitation and purity analysis.

The μDrop Plate consists of two separate measurement locations, one for measuring low-sample

volumes and the other for cuvettes. The μDrop Duo Plate consist of three separate measurement

locations, two for measuring low-sample volumes and one for cuvettes.

The low-volume area of the μDrop and μDrop Duo Plates is compatible with an 8-channel pipette to

enable easy pipetting of the samples to the μDrop and μDrop Duo Plates. It can be used for endpoint

and spectral measurements.

The cuvette slot is compatible with standard rectangular cuvettes with a stopper. It can be used for

endpoint, spectral and kinetic measurements.

Intended use

The μDrop and μDrop Duo Plates enable quick and easy absorbance measurements with low sample

volumes and standard rectangular cuvettes with a stopper. The main applications are photometric

nucleic acid and protein analysis.

The μDrop and μDrop Duo Plates are intended to be used in research laboratories by professional

personnel.

The μDrop and μDrop Duo Plates are designed to be a part of an analyzing system for the end user,

who is responsible for validating the system to ensure reliable and safe results. We recommend using

Good Laboratory Practice (GLP) during the analysis process.

General description

The μDrop Plate low-volume measurement area on the left-hand side consists of two quartz slides, the

top clear quartz and the bottom Teflon-coated quartz slide (see Figure 2). The bottom slide contains 16

sample positions, arranged in a 2 x 8 matrix, where samples are to be pipetted. The nominal pathlength

for the sample is fixed to 0.5 mm. The verified pathlength for each μDrop Plate is indicated on the

quality control measurement report delivered with the μDrop Plate.

The μDrop Duo Plate has two low-volume measurement areas on the left-hand side (see Figure 4). The

verified pathlengths for each μDrop Duo Plate are indicated on the quality control measurement report

delivered with the μDrop Duo Plate.

On the right-hand side, the μDrop and μDrop Duo Plates have a slot for cuvette measurement (see

Figure 1 and Figure 3).

the cuvette measurement point (3).

The measurement sessions for Multiskan SkyHigh, Multiskan Sky, Multiskan GO and Varioskan LUX

can be created using Thermo Scientific™ SkanIt™ Software. It is also possible to measure the μDrop and

μDrop Duo Plates with Multiskan SkyHigh and Multiskan Sky internal software ready-made

protocols.
