Patented* submicroliter cell technology for 0.3 ul analysis is only available with the NanoPhotometer™ Pearl and allows most reliable small volume analysis of nucleic acid or protein samples. Sample volumes starting from 0.3µl are pipetted onto the center of the submicroliter cell and a dilution lid is placed on top.

The dilution lids provide automatic dilutions of 5x, 10x, 50x, 100x or 250x by varying the distance the light travels (pathlength). Since the sample is completely enclosed, there is no reliance on sample surface tension or evaporation. The pathlength is fixed on each lid so the accurate result in small volume is provided during the entire life-time of the equipment. In addition, recalibration or maintenance is never required. For standard volume analysis, simply remove the submicroliter cell and use your plastic or quartz cuvettes.
