Micro Spectrophotometer
Model: K5500Plus

The ultra-micro spectrophotometer is a new type of full-wavelength spectrophotometer, which can detect nucleic acid, protein, colloidal, microarray samples, and conventional full-wavelength scanning, etc.

Features

1. Instrument control and operation: built-in win10 system, built-in 7-inch high-definition display, full touch operation.
2. Data output method: Built-in ≥32GB storage space.Users can directly store measurement result data and custom methods,which can be automatically saved in spreadsheet mode. USB output or network transfer data, with electronic manual.
3. Data output port: 2 USB ports, which can be connected to various devices such as mouse, keyboards, desktop computers, etc.
4. Built-in Bluetooth, WIFI, available to remote operation and print results data wirelessly.

1. Principle
The calculation of sample concentration is based on the Beer-Lambert law,
A = ε b c
Where A is the measured absorbance, ε is the molar absorption coefficient, b is the path length, and c is the concentration.
2. Range of application
The MD2000 series spectrophotometer can measure:
3. Nucleic Acid:
1, A260. The concentration and purity of DS-DNA, SS-DNA and RNA and others.
2, Micro Array. The concentration of fluorescent dye labeled nucleic acid (micro array), for it can measure the concentration of the nucleic acid and the dye at the same time.
4. Protein: 
1, Protein A280. The concentration of the protein (1Abs = 1mg/mL), BSA, IgG, Lysozyme, Labels and Others;
2, Protein Kit Method. The concentration of protein with protein assay kit (Lowry, BCA, Bradford and Others), and the software can create standard curves and report directly the concentration of the sample.
5. UV/VIS: 
The UV/VIS can measure full-spectrum (190~850nm) absorbance scan.
6. Cell Culture: 
It can measure the concentration of suspended cell cultures.
7. Kinetics: 
The instrument can make time-based kinetics measurements. The software only support kinetics measurement using cuvette module.
