ng/µL Concentration Calculator for Spectrophotometer / NanoDrop Scan
ng/µL Concentration Calculator: estimates dsDNA concentration as A260 × 50 (× dilution if a 'dilution' column exists), for a spectrophotometer / NanoDrop scan. Paste data, transform instantly, export CSV/JSON — 100% in your browser. For biochemistry and genomics labs.
Paste a spectrophotometer / NanoDrop scan and this tool estimates dsDNA concentration as A260 × 50 (× dilution if a 'dilution' column exists), then exports clean CSV or JSON ready for analysis. No upload and no R/Python needed — parsing and computation happen entirely in your browser, so biochemistry and genomics labs keep raw instrument data on the device.
Cleaned output
| sample | a260 | a280 | a230\ndna1 | 0.842 | 0.451 | 0.402\ndna2 | 1.204 | 0.640 | 0.560\nrna1 | 0.500 | 0.250 | 0.300 |
The parser auto-detects comma, tab, semicolon or pipe delimiters. After transforming, copy the CSV or download CSV/JSON for your pipeline. Always sanity-check the result against your raw data.
Indicative planning tool for research operations. Figures are estimates — verify lot data, expiry, calibration and budgets against the original certificates, vendor documentation and your institution's policies.

Why use ng/µL Concentration Calculator for Spectrophotometer / NanoDrop Scan?
- ✓Purpose-built for a spectrophotometer / NanoDrop scan: it estimates dsDNA concentration as A260 × 50 (× dilution if a 'dilution' column exists) in one paste — no spreadsheet gymnastics and no code.
- ✓Runs fully client-side, so raw instrument data never leaves the browser — important for biochemistry and genomics labs handling confidential or pre-publication results.
- ✓Exports clean CSV or JSON that drops straight into R, Python, Prism, Excel or your LIMS.
Frequently asked questions
What exactly does this tool do to my spectrophotometer / NanoDrop scan?+
It estimates dsDNA concentration as A260 × 50 (× dilution if a 'dilution' column exists). You paste the raw export, the parser detects the delimiter (comma, tab, semicolon or pipe), the transform runs, and you see the result plus a one-line summary of what changed. You can then copy the CSV or download CSV/JSON. It is deliberately one well-defined operation so the output is predictable and reproducible.
Is my instrument data uploaded anywhere?+
No. All parsing and computation happen locally in your browser with JavaScript — nothing is sent to a server. That keeps a spectrophotometer / NanoDrop scan private, which matters for biochemistry and genomics labs handling unpublished or confidential results, and it means the tool also works offline.
What input and output formats are supported?+
Input can be CSV, TSV, or semicolon/pipe-delimited text copied straight from your instrument software or a spreadsheet — the delimiter is auto-detected. Output is standard RFC-4180 CSV (copy or download) or a JSON array of objects keyed by the header row.
How should I sanity-check the result?+
Spot-check a few rows against your raw file, especially headers and any computed columns. This tool applies a single transform faithfully, but it can't know your specific column quirks — confirm it picked the right columns (e.g. the Cq, OD, area or A260 column) before using the output downstream.
