Instruments that measure ultraviolet and/or visible light absorbance of a sample; they are based on the Beer-Lambert law, which states that the concentration of a solute is proportional to the absorbance of the sample. Accessories available.
Designed for the laboratory, this COD colorimeter is a single parameter instrument for determining chemical oxygen demand index in water for markets such as wastewater, food & beverage, aquaculture, and agriculture.
Gather accurate chlorine measurements with a colorimeter designed for both the laboratory and the field in markets such as drinking water, wastewater, food & beverage, aquaculture, and agriculture.
Perform both basic and complex analyses with the Thermo Scientific™ GENESYS™ 30 Visible Spectrophotometer, an intuitive, reliable solution for education or in the lab.
Mettler Toledo Easy Vis Spectrophotometers measure visible light at multiple wavelengths with the Tungsten Lamp. Scan the UV Vis spectrum and record patterns with the peak finding function. 25 built-in color scales are included to receive results faster.
Avoid troubleshooting failed experiments with efficient analysis of your sample quantity and quality using the Thermo Scientifictm™ NanoDrop™ Eight UV-Vis spectrophotometer. Ideal for pharma/biotech and academic researchers measuring a larger number of nucleic acid and protein samples.
For DNA, RNA or protein samples that are 100% pure, the results obtained on the Thermo Scientific™ NanoDrop™ OneC Microvolume UV-Vis Spectrophotometer and the Invitrogen™ Qubit™ 4 Fluorometer would be identical for samples within their dynamic ranges.
Gain additional savings by bundling the purchase of a NanoDrop Eight Spectrophotometer with a Qubit™ Flex Fluorometer or a Multchannel ClipTip™ Pipette (Manual or Electric).
Quickly and easily assess sample concentration and purity ratios with the entry-level Thermo Scientific™ NanoDrop™ Lite Plus Microvolume Spectrophotometer. The instrument delivers accurate measurements in an easy-to-use, affordable package. Ideal for teaching and busy research labs.
