QuantStudio 12K Flex

Maximum Throughput

Maximize throughput with minimal resources.
Increase your throughput by as much as 32-fold by running 4 Applied Biosystems™ OpenArray™ plates in a single run on the Applied Biosystems™ QuantStudio™ 12K Flex system. It's the equivalent of 32 traditional 384-well qPCR plates or 12,000 data points.

Push your throughput even more.
When equipped with the OpenArray block, a single 9700 thermal cycler and the QuantStudio 12K Flex Applied Biosystems™ OpenArray™ AccuFill™ System, the QuantStudio 12K Flex system can produce up to 110,000 data points or more in an eight-hour day. 

Reduce start up time and hands on time.
Start a 12,000 data point experiment typically in 20 minutes or less.


Execute today and plan for tomorrow.

As you scale your experiments and move up in throughput, be assured that Applied Biosystems™ TaqMan™ Assay sensitivity, specificity, and wide dynamic range are optimized across all QuantStudio 12K Flex system block formats.

Even if you just have a few samples/targets to analyze, there is a TaqMan Assay format to fit your research needs.


Scientist using QuantStudio

Five interchangeable blocks.
Choose and load the thermal-cycling block you need for the experiment at hand (OpenArray plate, TaqMan Array Card, 384-well, Fast 96-well, and 96-well blocks).

Provides a seamless switch from qPCR to digital PCR.
Increase the precision and sensitivity of your nucleic acid experiment by switching from qPCR to digital PCR mode using QuantStudio Digital PCR kits and DigitalSuite Software with the QuantStudio OpenArray block.

Maximum multiplexing & chemistry options.
Proven fluorescence detection with Enhanced OptiFlex System (e.g. white light LED and 21 filter combinations for extremely accurate and sensitive data collection.

Integrated analysis and data quality.
Comprehensive software analysis tools for gene expression, genotyping, and digital PCR are available at your fingertips. Laboratory Information Management Systems (LIMS) and features that assist with 21CFR Part 11 compliance are enabled for high-throughput, validated environments.
