Trace UV Spectrophotometer
Model: MD2000
I. Product Features
1. Can detect simultaneously 8 samples;
2. Detection wavelength: 190–900 nm;
3. Small sample volume: Detection can be performed with just 1.5 μl of sample;
4. Nucleic acid detection range: 2–3000 ng/μl (dsDNA); samples can be directly loaded for testing without the need for concentration or dilution.
5. Rapid testing: Results available in approximately 15–20 seconds;
6. Convenient and quick to use: No warm-up required—simply turn it on and start measuring!
7. CCE calibration technology allows self-calibration without the need for a return trip.
8. Offers data traceability functionality compliant with international standards;
II. Product Applications
1. Nucleic Acid Concentration Assay: Measures the concentration of nucleic acids such as dsDNA, ssDNA, and RNA;
2. Probe Detection: Measure the absorbance of fluorescently labeled probes, which can be used to remove samples containing unlabeled probes.
3. Protein Concentration Assay: Measures the concentration of proteins in the sample;
4. Protein Assay Detection: Capable of detecting proteins whose concentrations have been precisely quantified using the BCA, Bradford, or Lowry methods, automatically generating a standard curve and calculating the concentration.
5. Detection of biomolecules such as carbohydrates and alcohols: Measure the sample's absorbance under conventional UV light.
6. Cell and Microbial Culture Assay: Measure the absorbance of cell and microbial cultures at 600 nm;
7. Kinetic Assays: Enzyme kinetics studies, standard curve generation;
