Product Description
The Nano-500 is a improved microspectrophotometer based on Nano-300 with full wavelength (200-800 nm). It added a function of fluorescence and without requiring a computer. With a sample size of only 0.5ul to 2ul, the sample concentration can be rapidly and accurately detected . The cutteve mode can be used to detect the concentration of culture media such as bacteria. The newly added fluorescence detection function, combined with the fluorescence quantitative analysis kit, can accurately quantify the concentration of DNA, RNA and protein through the specific combination of the fluorescent dye and the target substance, and the minimum limit can reach 0.5pg/ul(dsDNA)
• The nano-500 adds the following functions on the basis of the nano-300:
A . Increase the optical path by 0.05mm to make the detection of nucleic acid Increase the optical path by 0.05mm to make the detection of nucleic acid
B . Fluorescence detection function is added to accurately determine the concentration of DNA samples below 5ng/ul. In the detection of double-stranded DNA, the detection limit can be up to 0.5pg/ul (equivalent to increasing the function of Fluo-100 fluorometer produced by our company)
C . Automatic detect after put down the arm
• Patented motor lifting structure to prevent fluid column fracture due to structural problems, Increasing the detection stability. • Standard 00600 detection function.
• Android system, 7-inch capacitive touch screen, optimized APP software.
• High resolution CCD array detector, 6s can complete the detection and display results.
• Long life pulse xenon lamp light source.
• The detection data can be transferred to the computer through USB, which 1s convenient for data processing and analysis.The built-in printer can print the data directly.
New fluorescence detection function for Nano-500
In the process of sample detection, when the sample concentration is high or the sample is viscous, the determination by microspectrophotometer will often result in the failure of liquid column tension or even the direct fracture of liquid column, which will directly affect the result of detection .
In addition, when the sample concentration is high, some tiny bubbles are easily generated in the sample. When these bubbles are in the detection light, the detection results are not stable
Finally, because the stepper motor generates the liquid column in a gentler process, there will be less loss in the detection of the liquid. If the customer’s sample is very precious and needs to be recycled, stepper motor is more suitable for sample recovery.
Nano-500 adopts the patented sample stretching technology and the optical path length accuracy reaches 1 um，which effectively solves the above problems and makes the test results more stable and reproducible.
