How to use ultramicro cell
The ultramicro cell is a 10mm x 10mm cuvette that fits into the DNAmaster.
A 8.5 mm beam height was setup for DNAmaster. The cell has a system of fiber optics and prisms that will
reflect the light beam up to the sampling window and then back to the detector on the instrument. It is
supplied with a cap which contains a small mirror and it ensures that the sample is measured at constant
pathlength. The pathlength is achieved by a double pass through the sample as controlled by the cap height.
DNAmaster can setup the pathlength (shown in the cap).
Just need to pipette a small drop (0.5 – 10μl, depends on cap’s pathlength) of sample onto the window and
then places the cap on top. And then can start the measurement.
