Ideal for basic DNA/RNA/protein quantification and purity Affordable LED and silicon detector technology Fixed 0.5mm path length, detect up to 2500ng/µl of dsDNA SmartDrop L, NS1000 is the affordable choice for laboratories needing to determine nucleic acid and protein concentrations and purity of samples. The LED light source and silicon photocell sensor provide readings at 260 and 280nm. Samples from 1.0 to 2.0µl are loaded directly on the pedestal. Results are provided in about 5 seconds. The software automaticallycalculates and displays 260/280 ratios.
