Single stains can be measured by placing them on the  plastic background circles.

The black metal top plate (to be ordered separately - see below) functions as a weight to push the stains down. Depending on sample size, it may overlap.

The single stain holder plate, comes in various layouts for small or larger stains and in grey, white or black color. The default layout is shown here, contact us for a custom layout, for other colours than grey and to get a quote.
