Fast, Accurate and Flexible Analysis

The WNA-2/WNA-2S Microvolume UV-Vis Spectrophotometer is designed for fast and reliable analysis of DNA, RNA, proteins and other biological samples. Requiring only 0.5–2 μL of sample and delivering results in less than 6 seconds, it helps laboratories reduce sample consumption and improve daily testing efficiency.

With a 180–910 nm wavelength range, 7-inch touchscreen, Android operating system and xenon flash lamp, the instrument provides convenient UV-Vis measurement and data management. The WNA-2 offers additional OD600 and cuvette measurement functions, while the WNA-2S integrates fluorescence detection for higher-sensitivity analysis.

FAQ

1. What is the difference between WNA-2 and WNA-2S?

The WNA-2 provides microvolume UV-Vis measurement with additional OD600 and cuvette functions. The WNA-2S integrates a fluorometer for higher-sensitivity fluorescence measurement.

2. How much sample is required?

Only 0.5–2 μL is required for microvolume measurement, making the instrument suitable for limited or valuable samples.

3. How fast is the measurement?

Routine measurements can be completed in less than 6 seconds, helping improve efficiency when processing multiple samples.

4. Does the instrument require a computer?

No. The integrated 7-inch touchscreen and Android system allow users to perform measurements and manage data directly on the instrument. Optional PC software is also available.

5. Can the WNA-2S detect low-concentration DNA?

Yes. The integrated fluorometer provides higher sensitivity for low-concentration samples, with dsDNA sensitivity down to 0.5 pg/μL according to the product specifications.
