🧬 Are you trusting the wrong number before sequencing?

Most labs use a spectrophotometer for DNA/RNA quantification, but here's the problem: it measures everything that absorbs UV light. Contaminants, free nucleotides, residual phenol… all of it inflates your reading.

Qubit is different. It uses a fluorescent dye that only lights up when bound to your actual target. The result? Up to 3-4× more accurate than UV absorbance on the same sample.

So when should you use each?
✅ Spectrophotometer → quick purity check (A260/280, A260/230)
✅ Qubit → accurate concentration before NGS, qPCR, or cloning
✅ Both → when your sample is precious or impure

We broke down the science, the data, and the decision guide in our latest blog post. 👇
