1. SAH-769 One Drop Measurement Unit

The SAH-769 One Drop is a dedicated accessory for the V-600 and V-700 Series UV-visible spectrophotometers for the measurement of micro-volume samples of protein and nucleic acid.

A precise optical pathlength is maintained, assuring excellent measurement reproducibility. The sampling procedure is very quick (around 20 seconds per sample) and easy, by simply placing a droplet of a sample on the disk cell window.

The minimum sample volume is 5 µL for the standard 1 mm pathlength disk cell, and 0.6 µL for the optional 0.2 mm pathlength cell. The shorter optical pathlength allows measurements of high concentration samples without dilution.

2. EMC-709 Micro Cell Holder

The EMC-709 is a micro cell holder for micro volume cells (approx. 50 µL or smaller).

For use with rectangular micro cells with a path length up to 10 mm and a width of 2 mm, minimum.

3. EMC-759 5 µL Ultra-Micro Cell Holder

The EMC-759 micro cell holder for micro volume cells (approx. 5 µL) can be used for minimal volume samples.

Rectangular micro cells with a path length of 1 mm and a width of 2 mm are specified for use with this cell holder, using a lens to focus the light beam into the cell for precise low-volume measurements.

4. 5 µL Micro Cell (stepped type)

This micro-volume cell (5 µL volume) is designed so that a pipette tip can reach the cell bottom and sample recovery can be easily performed.

The dedicated cell holder, model EMC-759, is required to use this cell and the light beam is condensed using a lens integrated into the cell holder.

Optimum measurements are obtained by reducing the source beam energy losses due to diffraction.
