QIAxpert is the right tool for any fast-paced lab performing nucleic acid quantification and quality control.
Thermo Scientific™ NanoDrop 8000 is a muti-sample micro-volume UV-Vis spectrophotometer. With the NanoDrop 8000, you can measure more samples in less time with the same reliability and patented sample retention technology of the NanoDrop 2000.
The FLUOstar Omega is a multifunctional microplate reader that supports a wide variety of applications and the following reading modes: fluorescence intensity, time-resolved fluorescence, absorbance and luminescence.
Enhance the limit of detection for DNA, RNA and protein with the Thermo Scientific NanoDrop 2000c UV-Vis spectrophotometer featuring both microvolume pedestal and cuvette measurement options. The cuvette station is ideal for measuring dilute nucleic acid and protein assays, includes heating and microstirring capabilities, and allows users to perform kinetics and cell culture readings (600nm).
Nanodrop 2000C Specifications:
Simple to use instrument for measuring absorbance and concentration. It provides stored routines for nucleic acid quantitation and also a standard curve routine for protein determination. Wavelength scan with zoom, absorbance changes with time, reaction rate determinations, and standard curves can be displayed and printed out. User defined equations can be entered using the multi-wavelength mode and up to 18 methods can be saved. Ultrospec 2100 Pro is a versatile and reliable instrument for use in any laboratory.
Epoch Microplate Spectrophotometer includes monochromator-based optics that provides filter-free, wide wavelength range for UV-Vis absorbance measurements in various microplate formats. This spectrophotometer is controlled by Gen5 Software that allows intricate data analysis, yet simple programming. This product is cost-effective and requires low maintenance.

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. SOFTmax PRO microplate data- analysis software- for use with the SPECTRAmax 250- provides built-in spreadsheet capabilities for easy data analysis and reporting.
The Direct Detect system provides accurate results without the pitfalls of colorimetric assays. By measuring amide bonds in protein chains, the system accurately determines an intrinsic component of every protein without relying on amino acid composition, dye binding properties or reduction-oxidation (redox) potential. Also, evaluation of other components of complex mixtures separable from the protein spectral region, like lipids, make lysates and membrane preps easier than ever.
