Fast, accurate DNA, RNA, and protein quantification for a single sample
The Invitrogen Qubit 4 Fluorometer accurately and quickly measures the concentration of DNA, RNA, or protein in a single sample. It can also be used to assess RNA integrity and quality. The easy-to-use touchscreen menus make it easy to select and run the assays you need, with results displayed in just a few seconds.
Features
The Qubit 4 Fluorometer shares common features with the Qubit Flex model: It is accurate, specific, sensitive, simple, and fast; it requires as little as 1 µL of sample, even if highly diluted; it offers an onboard Reagent Calculator to help in preparing your working solution; it works with a broad range of Qubit Assays and applications; and it can measure raw fluorescence in Fluorometer mode.
In addition, data gathered in Fluorometer mode on the Qubit 4 Fluorometer can be used to design your own assay using the MyQubit assay design tool. This tool lets you create new assays for the Qubit Fluorometer in minutes. Simply enter your assay parameters into the online tool, and then save and upload the .qbt file to your Qubit Fluorometer using a USB drive.
Preconfigured MyQubit assays to quantify cholesterol, galactose, glucose, glutamic acid, peroxide, or sucrose are available. You can download these .qbt files to your computer and then upload them to your Qubit 4 Fluorometer using a USB drive. These are examples of the kinds of MyQubit assays you can create on your own.
Simple workflow
The user-friendly Qubit 4 Fluorometer delivers results using quick, simple assay procedures. The large, color touch screen allows you to easily navigate through the various options. Calculations and settings are automatically performed by the instrument.
The Qubit 4 Fluorometer will save the data for up to 1,000 samples, and you can transfer data to a Thermo Fisher Connect Cloud account via WiFi, or to a computer via a USB drive or cable. In addition, the Qubit 4 integrated Reagent Calculator helps you determine the amount of dye and buffer required to prepare your samples and standards.
Reagent Calculator and results graph. Enter the number of samples and standards needed and the built-in Reagent Calculator will determine the amount of dye and buffer needed. The results can be viewed on a graph showing the standard curve.
