Great precision but expensive kit
Rating: 4.0

  • Application Area: DNA RNA quantification

"We got this Qubit Flex Fluorometer for our DNA RNA quantitation needs. Using this needs a little more as compared to the typical Nanodrop but once you have your standard, you are good to go. It definitely is more precise than the Nanodrop and not for your quick and dirty quantification. I will save this assay kit for more critical jobs rather than quantification for routine cloning work."

Flex your throughput.

The Invitrogen Qubit Flex Fluorometer can selectively, accurately measure the concentration of up to 8 samples of DNA, RNA or protein simultaneously. Compared to single sample microvolume fluorometers, using the Qubit Flex Fluorometer for multiple samples reduces your time to data by up to 50%, with time savings beginning with batches of as few as 8 samples. Combining the one-of-a-kind Qubit Flex Fluorometer and optimized Invitrogen Qubit reagents and tube strips offers a complete solution for DNA, RNA and protein quantification.

Key features of the Qubit Flex Fluorometer:


  • Improved throughput: Measure up to 8 samples per run
  • Assay range and reagent calculators for easy sample prep
  • Sample calculators for NGS workflows
  • More sensitive than UV absorbance–based quantification
  • Uses as little as 1 μL of sample, making it ideal for precious samples
  • Accurately quantifies DNA, RNA, and protein in < 3 seconds per sample
  • Superior ease of use and small footprint
  • Easy data export with WiFi and cloud capability
  • Same optimized Qubit reagents
