Our range of qPCR systems allows you to tailor your research to your specific strategies and budget. Ongoing innovations in qPCR technology enhance performance across the QuantStudio portfolio, including:
QuantStudio real-time PCR systems offer advanced features designed to enhance your research capabilities. With the OptiFlex system, these instruments offer improved data accuracy and enable advanced multiplexing of multiple genes. The systems support both TaqMan- and SYBR-based assays within the same run, for flexibility and efficiency. Additionally, QuantStudio systems allow for remote monitoring and secure data sharing through Thermo Fisher Cloud, making it easier to access and collaborate on your results from anywhere.
With the advanced instrument management capabilities of AccuSEQ software v4.0, you can discover and add instruments in 3 easy steps.
With the advanced instrument support capabilities of AccuSEQ software v4.0, you can rapidly switch between QuantStudio 7 Pro and QuantStudio 5 instruments and block types
QuantStudio real-time PCR systems can detect subtle changes in gene expression, as small as 1.5-fold, which may be overlooked by other systems. With a dynamic range of up to 10 logs, these systems can track extensive changes in expression across various sample types and conditions.
QuantStudio systems feature the OptiFlex system to help enhance data accuracy between wells and across instruments. This system supports advanced multiplexing of multiple genes by using decoupled excitation and emission filter channels. Additionally, the OptiFlex system allows for both TaqMan- and SYBR-based assays to be conducted within the same run.
QuantStudio systems offer varying numbers of excitation and emission filters, ranging from 3 on the QuantStudio 1 system to 6, with up to 21 filter combinations on the QuantStudio 7 Pro system. This enables the quantification of multiple genes within a single experiment for maximum flexibility for experimental design. The table below outlines the dye compatibility for each system.

Help optimize your laboratory space with the QuantStudio 7 Pro, which features interchangeable blocks to adapt to your evolving needs. Options range from 96-well plates for small-scale optimization to 12,000 data points—using four OpenArray plates with 3,072 through-holes each—on select systems. The blocks can be easily swapped without tools.
Most QuantStudio systems are equipped with 96-well VeriFlex blocks featuring 3–6 zones. These blocks are designed for precise temperature control, minimizing small variances that can cause inconsistent results. Each zone can be set to a different temperature within a single run, enabling multiple experiments to be conducted simultaneously and enhancing productivity.
Touchscreens help simplify editing and reduce errors with experimental conditions and viewing plate layouts. Pre-optimized protocol templates and locked workflow features are designed to enhance experimental consistency. As experiments run, results are displayed in real-time, allowing you to focus on specific graphs or data points as needed
Quickly and easily change blocks—for example, 96- to 384-wells—with no tools required. On-board software guides through a simple process.
The QuantStudio 7 Pro real-time PCR system offers exceptional flexibility to support various applications and throughput needs. Designed with smart features to reduce contamination, it allows hands-free setup and remote scheduling and monitoring from your mobile device. The system's 96-well blocks with VeriFlex technology offers precise temperature control with isolated zones for separate cycling conditions within the same run, well suited for optimization. The QuantStudio 7 Pro System also supports interchangeable blocks for increased throughput, accommodating 96-well, 384-well, and TaqMan array cards. Additional features include automation compatibility and software to assist with 21 CFR Part 11 compliance.
In addition to the common features of all QuantStudio systems, the QuantStudio 7 Pro system offers:
The QuantStudio 5 real-time PCR system is factory-calibrated for rapid installation and immediate use. It can detect target quantity differences as small as 1.5-fold and supports remote monitoring. Enhanced functionality is provided through optional cloud-based Applied Biosystems analysis modules and data sharing. Suitable for both novice and experienced users, the QuantStudio 5 system accommodates 96-well (0.2 mL or 0.1 mL) and 384-well consumables. It also offers multiplexing capabilities for up to 6 targets and includes an SAE package and software to support 21 CFR Part 11 compliance.
The QuantStudio 5 system is an excellent choice for simplicity and flexibility when it comes to straightforward applications. The QuantStudio 7 Pro system is designed for more complex, high-throughput applications that require advanced automation and data management features.
