The Invitrogen Qubit 4 Fluorometer by Thermo Fisher Scientific is a high-precision benchtop instrument designed for fast, accurate fluorescence-based quantitation of DNA, RNA, and protein in molecular biology research. It uses target-specific fluorescent dyes that emit a signal only when bound to the molecule of interest, delivering far greater sensitivity and specificity than traditional UV absorbance methods. The instrument is re-engineered to support the Qubit RNA IQ (integrity and quality) assay, enabling researchers to distinguish intact from degraded RNA in just two steps.

Key Features:
- Fast and highly accurate quantitation of DNA, RNA, and protein in less than 3 seconds per sample
- Measures intact RNA in less than 5 seconds per sample
- Accepts sample volumes of only 1–20 µL, even from very dilute samples
- Large 5.7-inch colour touchscreen for intuitive workflow navigation
- On-board Reagent Calculator for working solution preparation
- Stores results from up to 1,000 samples
- Exports data via USB drive, USB cable to computer, or WiFi to Thermo Fisher Connect Cloud
- Compatible with MyQubit software and web tool for custom assay creation
- Supports multiple languages: English, French, Spanish, Italian, German, Simplified Chinese, and Japanese
- Graphical display indicates extended range or out-of-range samples
- For Research Use Only — not for diagnostic procedures
