The device displays a baseline; adjust if it deviates from the reference; Repeat for 280 nm and 340 nm. Store calibration data in memory. Connect before calibration!!!
4.1 Daily Calibration
Before each measurement session, perform a quick daily calibration to maintain instrument accuracy. Place a 1 µL cuvette of high‑purity, deionized water on the pedestal. Close the lid, then select the “Daily Calibration” routine from the main menu. The system will automatically measure absorbance at 260 nm, 280 nm, and 340 nm, comparing results to the built‑in reference values. If the readings deviate by more than ±0.005, the device will prompt you to adjust the baseline. Follow the on‑screen instructions to set the zero point. Once the calibration is accepted, the NanoDrop One will store the values in its internal memory, ensuring consistent performance for the rest of the day. Remember to record the calibration date and time in your lab notebook for traceability. Additionally, check the optical alignment by running the “Optical Check” sub‑routine; any misalignment will be flagged and corrective action recommended. Keep the pedestal clean with a lint‑free wipe and ensure the cuvette is free of bubbles, as trapped air can skew the baseline. Finally, verify the software version matches the latest firmware; an update can improve baseline stability and extend the instrument’s service life. By adhering to this calibration protocol, you maintain precision, reduce variability, support data integrity across experiments. Document deviations and corrective actions for audits, ensuring compliance.! Ensure all data is logged.
4.2 Calibration Check
After completing the daily calibration, the NanoDrop One performs an automated calibration check to verify instrument stability. Select “Calibration Check” from the main menu; the device will automatically acquire a reference spectrum using a calibrated reference cuvette. The system compares the measured absorbance values at 260 nm, 280 nm, and 340 nm against stored reference tolerances. If all readings fall within ±0.002 of the target, the check passes and a green status indicator appears. Should any parameter exceed the tolerance, the display will show a warning and recommend a re‑calibration. In that case, repeat the daily calibration routine and re‑run the check. The calibration check records the optical density at 260 nm and 280 nm for trend analysis; these values are saved in the instrument log and can be exported via USB for quality control documentation. Performing the calibration check at the start of each session ensures that any drift or contamination is detected early, maintaining data integrity for downstream analyses. Regular calibration checks are essential for compliance with regulatory standards and for ensuring reproducibility across experiments. The check routine runs in under 30 seconds, fitting high‑throughput workflows. Users can schedule automated checks via the calendar feature.

Use “Quick” for fast checks or “Full” for spectra; The instrument auto‑calibrates baseline and applies temperature correction, calculating concentration. All data are logged !
5.1 Sample Loading
Before initiating a measurement, ensure the NanoDrop One is powered on and the software is running. Gently lift the sample chamber lid using the designated handle; the lid should slide smoothly without resistance. Using a calibrated pipette, transfer 1–2 µL of the sample onto the glass pedestal. Avoid touching the glass with the pipette tip to prevent contamination. Allow the liquid to spread evenly; the pedestal’s micro‑drop surface will automatically form a stable droplet. Do not overfill; excess liquid can spill into the optical path and skew results. After loading, close the lid by pressing the latch until it clicks, confirming a secure seal. The device will then prompt you to select the measurement mode. For nucleic acid quantification, choose “DNA/RNA” and for protein assays, select “Protein.” Once the mode is set, press the “Start” button. The instrument will perform a baseline correction, then acquire absorbance data across the selected wavelength range. Upon completion, results are displayed on the screen and can be saved to the connected computer. Proper sample loading ensures accurate absorbance readings and reliable concentration calculations. Always clean the pedestal with a lint‑free wipe between samples to maintain optical clarity.
Tip: Use low‑binding pipette tips to reduce sample loss. If measuring viscous solutions, pre‑warm to room temperature. Avoid bubbles; tap gently to remove. The pedestal is designed for single‑use; do not reuse. If you need to measure multiple samples, repeat the loading process for each. The NanoDrop One’s software allows you to create a sample list for batch processing, reducing manual repetition.
Safety: Handle the glass pedestal with care; it is fragile. Do not apply excessive force. The device’s internal temperature sensor monitors ambient conditions; if the temperature deviates beyond ±2 °C, a warning will appear. In such cases, pause the measurement and allow the instrument to equilibrate.
Documentation: After each measurement, review the data sheet. The software logs sample ID, volume, and absorbance values. Ensure the sample ID matches the lab notebook entry. This practice aids in traceability and quality control.
Troubleshooting: If the instrument reports a “Sample Too Small” error, verify that the droplet covers the entire pedestal area. If the error persists, check for residual liquid on the pedestal from previous runs.
