The NanoDrop 1000 Spectrophotometer measures 1 ul samples with high accuracy and reproducibility. The full spectrum (220nm-750nm) spectrophotometer utilizes a patented sample retention technology that employs surface tension alone to hold the sample in place. This eliminates the need for cumbersome cuvettes and other sample containment devices and allows for clean up in seconds. In addition, the NanoDrop 1000 Spectrophotometer has the capability to measure highly concentrated samples without dilution (50X higher concentration than the samples measured by a standard cuvette spectrophotometer).

The SPECTRAmax 250 microplate spectrophotometer has a xenon flash lamp and grating monochromator that facilitate direct UV measurement of DNA- RNA- and protein in microplates. Up to 96 assays can be run at one time using disposable or quartz microplates. The purity of DNA can be measured with A260/A280 ratios. Also- users can perform spectral scans from 250 nm to 750 nm to simplify qualitative analyses of numerous samples. The product reportedly reduces sample volumes in experiments because the assays are performed in a microplate instead of cuvettes.
