The Applied Biosystems QuantStudio 12K Flex Real-Time PCR System can simultaneously run up to four 3,072-reaction QuantStudio 12K Flex OpenArray plates in about four hours. When combined with the QuantStudio 12K Flex OpenArray AccuFill System, the QuantStudio 12K Flex system can produce up to 110,000 data points or more in an 8-hour day with as little as 20 minutes of hands-on time per run. A feature-rich touch screen interface and comprehensive software analysis tools for gene expression, and genotyping increases productivity.


Designed for the highest flexibility, the QuantStudio 12K Flex system has five-interchangeable block formats including: OpenArray plate, TaqMan Array card, 384-well, and 96-well (0.1 and 0.2 mL). This delivers unmatched versatility for the lab with flexible format requirements. The system also includes laboratory information management system (LIMS) support and features that assist with 21CFR Part 11 compliance are enabled for high-throughput, validated environments.

Sample data


9-log separation



Real-time PCR reproducibility and 9-log dynamic range. Amplification plot shows results from real-time PCR of 18S DNA in 10-fold dilutions starting at 25,000 copies using the 384-well block. The data show highly reproducible results for input target quantities covering nine orders of magnitude (9 logs).
