High sensitivity colorimetry with comparator block and colour comparison disc. In comparison with other VISOCOLOR® kits, their sensitivity is enhanced by increasing the length of the test tube and the use of highly sensitive reagents. This technique allows a 10- to 100-fold increase of sensitivity. Each VISOCOLOR® HE test kit is packed in a sturdy plastic box which contains the comparator block with colour comparison disk and all required reagents.
