Description

The Fluorometer YG1689-A is a high-precision, compact benchtop instrument designed for ultra-sensitive quantification of nucleic acids and proteins in biological and biochemical research. With a detection limit as low as 0.5 pg/μL for DNA, it surpasses traditional absorbance-based systems in accuracy and reliability, making it ideal for low-concentration sample analysis. Its 4.3-inch touchscreen and intuitive interface allow users to conduct measurements in under 3 seconds, simplifying the workflow in molecular biology, medicine, environmental monitoring, and plant physiology labs. Equipped with dual fluorescence channels, the YG1689-A supports simultaneous quantitation of DNA/RNA and protein in a single detection cycle, while offering flexible compatibility with various reagents through its open system design.

Frequently Asked Questions

• What is the difference between this fluorometer and absorbance-based systems?
  Unlike absorbance-based methods that read total content at 260nm, the YG1689-A detects fluorescence intensity from reagent-molecule complexes, providing much higher sensitivity and accuracy.
• Can I use any reagents with this instrument?
  Yes, the system is open, allowing users to choose and match their preferred quantitation kits or reagents.
• Is data export possible?
  Absolutely. The fluorometer can store up to 1,000 measurements and supports USB data export for seamless integration with lab information systems.

Advantages and Disadvantages

Advantages:

• High sensitivity with a DNA detection limit of 0.5 pg/μL, ideal for trace-level quantification.

• Dual-channel detection allows simultaneous analysis of DNA/RNA and protein.

• Compact and lightweight (only 0.4 kg), with a rapid 3-second measurement time.

Disadvantages:

• Requires fluorescent reagents, which may have an additional cost compared to basic absorbance systems.

• Open system may require validation of third-party kits for consistency.

• Limited screen size may be less optimal for batch data analysis without export.

Product Use in the Field

The YG1689-A is widely used in genomics, proteomics, pharmaceutical development, and plant biology research. Its fast, sensitive quantification is critical for accurate DNA/RNA measurements in qPCR prep, forensic investigations, or environmental DNA (eDNA) sampling. In agricultural and environmental labs, it aids in measuring chlorophyll fluorescence to assess plant health. The device’s small footprint and low reagent consumption make it a cost-effective and space-saving solution for high-throughput labs and research institutions alike.

Recommendations

To ensure optimal performance, use high-quality qPCR tubes and fluorescent reagents compatible with the YG1689-A’s detection wavelengths. Regularly update the system’s software via USB and calibrate as per manufacturer guidelines. Keep the optical sensor area clean and handle low-volume samples with precision pipettes to maintain measurement accuracy. By following these practices, labs can maximize the fluorometer’s efficiency and ensure consistent, reproducible results.
