This Invitrogen Qubit 4 Fluorometer (catalogue number Q33226) is new open box, in excellent cosmetic condition with like-new appearance. The unit has been tested and is confirmed fully working. Software version is APP 2.10 + MCU v0.27.

All six assay modes are active and available from the home screen:
• dsDNA
• RNA
• Oligo (ssDNA)
• Protein
• Ion Sphere
• Fluorometer (raw fluorescence mode)

WiFi connectivity is supported via the included Thermo Fisher Scientific 802.11 bgn USB dongle, enabling data transfer to the Thermo Fisher Connect Cloud.

This unit is supplied with:
• UK mains power adapter (12V DC)
• USB-A to Mini-USB data cable
• Thermo Fisher Scientific WiFi USB dongle
• Qubit Protein Buffer (accessory bottle)
• Original retail packaging box
• Certificate of Conformance

For Research Use Only. Not for use in diagnostic procedures.

The Invitrogen Qubit 4 Fluorometer is the latest version of the popular Qubit benchtop fluorometer, designed to accurately measure DNA, RNA, and protein quantity, and also RNA integrity and quality, using the highly sensitive and specific Qubit fluorescence-based assays. Re-engineered to support the Qubit RNA IQ (integrity and quality) assay, it accurately distinguishes intact from degraded RNA in just two easy steps.

Key features and highlights:
- Fast and highly accurate quantitation of dsDNA, RNA, oligonucleotides, and protein in under 3 seconds per sample
- RNA integrity and quality measurement (RNA IQ assay) in under 5 seconds per sample
- Accepts sample volumes of only 1–20 µL, providing accurate results even at very low concentrations
- Far more sensitive and specific than UV absorbance methods — fluorescent dyes emit signal only when bound to the target molecule
- Large 5.7-inch colour touchscreen for easy workflow navigation
- On-board Reagent Calculator for quick working solution preparation
- Stores up to 1,000 sample results; exports data via USB drive, USB cable, or WiFi
- Compatible with MyQubit software for custom assay creation
- Ion Sphere Particle quality assessment supported for Ion PGM sequencing workflows
- Multi-language support: English, French, Spanish, Italian, German, Simplified Chinese, Japanese
