Invitrogen™ Qubit™ Flex Fluorometers and Starter Kits

Description
The Qubit Flex Fluorometer is designed for highly accurate and sensitive quantification of DNA, RNA, microRNA, protein, and endotoxin. This benchtop fluorometer offers the flexibility to directly measure the fluorescence of up to eight samples simultaneously, which reduces assay variability. Paired with Qubit reagents, the Qubit Flex Fluorometer is part of an optimized workflow generating highly accurate and reproducible results. The fluorometer has a large screen and intuitive user interface, making it easy to select and run your desired assay with results displayed in just a few seconds.
Features of the Qubit Flex Fluorometer include:
- Improved throughput—measure multiple samples and quantify DNA, RNA, protein, and endotoxin up to 50% faster than single-sample readers
- Flexibility—measure up to eight samples simultaneously using 1–20 μL of sample
- Complete optimized system—works seamlessly with Qubit reagents to generate reliable, sensitive, and specific results
- On-board calculators—quickly generates Qubit working solution preparation instructions and determines the molarity of your samples
- Easy to use—a large 8-inch, state-of-the-art color touchscreen and intuitive user interface results in easy workflow navigation
- Data export flexibility—data is transferred easily as a CSV or PDF using the included Wi-Fi dongle, a USB drive, or connection to your network drive
- Several languages available—choices include English, French, Spanish, Italian, German, simplified Chinese, and Japanese
- Verification test—a pre-loaded program is included to verify performance of the instrument
- Qubit Flex SmartStart Digital Educational Experience—includes interactive visual demonstrations of how to install, operate, and maintain your instrument
Higher throughput, less variability than single sample readers
The Qubit Flex Fluorometer has the flexibility to measure multiple DNA, RNA, protein, and endotoxin samples up to 50% faster than single-sample readers. In addition to saving time, the ability to measure eight samples simultaneously reduces variability, resulting in highly reproducible data. The fluorometer includes reagent, range, and molarity calculators, further reducing the time to results. The reagent and range calculators help to determine which reagent and what amount of sample to use to effectively quantify the DNA, RNA, or protein. The molarity calculator allows you to calculate the molarity of your samples based on nucleic acid length and the measured concentration.
Enables more accurate results than UV absorbance at low concentrations
The Qubit Flex Fluorometer is far more sensitive than UV absorbance, which measures anything absorbing at 260 nm, including DNA, RNA, protein, free nucleotides, and excess salts. Moreover, UV spectrophotometry is often not sensitive enough to accurately measure low concentrations of DNA and RNA. With the Qubit Flex Fluorometer, your research is enhanced by more accurate measurements because the dyes in the Qubit assay kits fluoresce only when bound to the target molecule (DNA, RNA, protein, or endotoxin) in your sample. This allows you to avoid repeating work due to inaccurate measurements.
