This equipment is able to perform two measurement modes: Fluorescence and absorbance; the principle of operation of the instrument is based on the measurement of light signals by two fluorescence channels for nucleic acid, quantification of proteins in a single detection. The light signal that affects the detectors is converted by high gain amplifiers to voltage signals that are in turn digitized and stored in memories for further processing.

In the fluorescence measurement, a fluorescent lamp emits ultraviolet light (365nm) that hits and excites the sample. The resulting signal is picked up by the detectors. Fluorescence measurement uses internal standards to consider the references 0.0 and 100.0 when reading strips. A value of 0.0 refers to the fluorescence of 10 L of water and a value of 100.0 refers to the fluorescence of 10 L of a 1:10 dilution of 4-methylumbeliferone of concentration 4.7x10-5 M. This equipment can store a maximum of 1,000 data and output data per USB port.


Our Best Selling Fluorometer

A fluorometer measures fluorescence parameters and their intensity and wavelength distribution of the emission spectrum after excitation by a certain spectrum of light. Applications include chemistry/biochemistry, medicine, environmental monitoring. That means they're used to measure chlorophyll fluorescence to investigate plant physiology. These are key devices in any biological laboratory, especially for research. That's why we present you with this high-tech device, to turn your laboratory into a reliable company.YR412-A is your solution, since it is able to measure the absorbance of all the ingredients (such as DNA, RNA, oligos, etc.) of the sample at 260 nm, but keep in mind because that can make the reading inaccurate. The fluorometer measures the fluorescence intensity of the fluorescent reagent, which is combined with the target molecule to read the sample concentration. In general, the reading is lower than that of the Nano series products, but it is much more accurate. The sensitivity of Nano series products is higher than 5 ng/ul, while the fluorometer measures 0.5 pg/ul to measure the DNA concentration. It is important and necessary for most applications to read the lowest and most accurate sample concentration. With the fluorometer YR412-A with the quantification kit, you can measure the sample concentration quickly, sensitively and accurately.
