QuantStudio 1 Plus Real-Time PCR System (Domestically Manufactured, Thermo Fisher Brand)

Overview

The QuantStudio 1 Plus Real-Time PCR System (Domestically Manufactured, Thermo Fisher Brand) is a compact, factory-calibrated real-time fluorescent quantitative polymerase chain reaction instrument engineered for precision, reproducibility, and operational simplicity in molecular biology laboratories. It operates on the principle of sequence-specific nucleic acid amplification coupled with real-time fluorescence detection—enabling quantification of DNA targets during exponential amplification via hydrolysis probes (TaqMan®), intercalating dyes (e.g., SYBR Green I), or hybridization probes. Designed for routine qPCR applications—including gene expression analysis, genotyping, pathogen detection, and miRNA profiling—the system delivers high thermal uniformity across its fixed 96-well aluminum block and maintains precise temperature ramping rates (±0.25 °C accuracy, ±0.5 °C uniformity) to ensure assay robustness and inter-run comparability. Its architecture conforms to core laboratory instrumentation standards for thermal stability, optical signal fidelity, and data traceability—supporting alignment with GLP-compliant workflows and internal quality control requirements.

Key Features

• Integrated 8.5-inch high-resolution capacitive touchscreen interface for intuitive, glove-friendly operation without external peripherals
• Fixed 96-well 0.2 mL thermal block with manually actuated drawer mechanism—optimized for consistent thermal transfer and minimal well-to-well variation
• Four-channel optical detection system with pre-aligned excitation/emission filters for FAM, VIC, ROX, and Cy5—calibrated for broad dye compatibility including SYBR Green I, JOE, Texas Red, LIZ, and MUSTANG Purple
• Reaction volume range of 10–100 µL accommodates standard low-volume assays as well as higher-volume validation runs
• Factory-installed thermal and optical calibration—eliminates user-performed baseline or background calibration prior to first use
• Compact footprint (40 × 27 × 50 cm) and lightweight design (<26 kg) facilitate benchtop deployment in space-constrained environments such as QC labs, clinical research units, or teaching facilities

Sample Compatibility & Compliance

The QuantStudio 1 Plus supports standard 96-well PCR plates and tubes compliant with ANSI/SLAS dimensional specifications. It is validated for use with common qPCR reagents—including TaqMan assays, SYBR Green master mixes, and third-party probe- or dye-based chemistries—without hardware modification. While not CE-IVD or FDA 510(k)-cleared for diagnostic use, the system meets general-purpose research instrumentation requirements under ISO 9001-certified manufacturing protocols at the Shanghai production site. Data integrity features—including audit-trail-enabled software logging in cloud mode and timestamped run metadata—support alignment with internal SOPs and regulatory expectations for non-GMP research environments. All firmware and software updates are distributed through Thermo Fisher’s secure update infrastructure, ensuring version consistency across instrument fleets.

Software & Data Management

Two validated software pathways are provided: QuantStudio Design and Analysis Cloud Software and QuantStudio Design and Analysis Desktop Software. The cloud-based application operates entirely within modern web browsers (Chrome, Edge, Firefox) on Windows, macOS, or Linux systems—requiring no local installation, license keys, or manual version management. It integrates natively with Thermo Fisher Connect™, a HIPAA- and GDPR-aligned cloud platform offering AES-256 encrypted storage, role-based access control, and collaborative annotation tools. The desktop variant supports Windows 10 (64-bit) and provides offline analysis capability with local file encryption and export options compliant with FAIR data principles (Findable, Accessible, Interoperable, Reusable). Both platforms generate MIQE-compliant reporting templates and support batch analysis, melt curve deconvolution, relative quantification (ΔΔC_t), and efficiency-corrected standard curve fitting.

Applications

This system is routinely deployed in academic research labs for differential gene expression profiling across tissue types or treatment conditions; in biopharmaceutical quality control for plasmid copy number verification and residual host-cell DNA quantification; and in public health laboratories for rapid screening of viral RNA (e.g., SARS-CoV-2, influenza A/B) using validated RT-qPCR protocols. Its sensitivity—capable of resolving ≤1.5-fold differences in starting template concentration—makes it suitable for low-abundance transcript detection and allelic discrimination assays. Pre-optimized protocol templates for common applications (e.g., “Gene Expression,” “Genotyping,” “Presence/Absence”) reduce method development time while maintaining analytical rigor.

FAQ

Is the QuantStudio 1 Plus certified for clinical diagnostics?
No—this configuration is designated for research use only and is not approved for in vitro diagnostic (IVD) applications under FDA, CE-IVD, or NMPA regulatory frameworks.
Can I import custom assay configurations or primer/probe sets?
Yes—both cloud and desktop software support user-defined assay libraries, including custom dye assignments, quencher types, and amplification efficiency assumptions.
Does the system support remote monitoring during a run?
Yes—when connected to a local network and linked to Thermo Fisher Connect™, users can monitor real-time amplification plots, cycle thresholds, and instrument status from any authorized device with internet access.
What maintenance is required beyond routine cleaning?
No scheduled optical recalibration or thermal sensor servicing is required during normal operation; periodic verification using Thermo Fisher-provided reference plates is recommended annually per lab quality policy.
Is raw fluorescence data export supported?
Yes—both .eds (instrument-native) and .csv formats are available for downstream statistical analysis in R, Python, or MATLAB environments.
