Unique rotary design for outstanding performance
The unique centrifugal rotary design of the Rotor-Gene Q makes it the most precise and versatile real-time PCR cycler currently available (see figure " Cross-section of the Rotor-Gene Q"). Each tube spins in a chamber of moving air, keeping all samples at precisely the same temperature during rapid thermal cycling. Detection is similarly uniform. When each tube aligns with the detection optics, the sample is illuminated and the fluorescent signal is rapidly collected from a single, short optical pathway. This thermal and optical uniformity results in sensitive, precise, and fast real-time PCR analysis (see figure " Precise real-time PCR analysis"). It also eliminates sample-to-sample variations and edge effects. These are unavoidable in traditional block-based instruments due to temperature gradients across the block and multiple, complex optical pathways.
The rotary design delivers:
- Tube-to-tube variation ±0.02°C
- Uniform detection eliminating the need for ROX reference dye
- Fast ramping and negligible equilibration times for short run-times
- Complete confidence in your results
Unrivaled optical range enables multiple applications
Whether your assay is based on intercalating dyes such as SYBR® Green, probes such as hydrolysis (TaqMan®), hybridization (FRET), Scorpion probes, or other multiplex chemistries, the Rotor-Gene Q meets your requirements. With up to 6 channels spanning UV to infrared wavelengths, the cycler delivers the widest optical range currently available (see table). In addition, the software allows you to create new excitation/detection wavelength combinations, which means that the Rotor-Gene Q is compatible with dyes you may use in the future.

Expand your research with HRM
High-resolution melting analysis (HRM) is a closed-tube, post-PCR analysis that has raised enormous scientific interest. HRM characterizes double-stranded PCR products based on their dissociation (melting) behavior. It is similar to classical melting curve analysis, but provides far more information for a wider range of applications. PCR products can be discriminated according to sequence, length, GC content, or strand complementarity, down to single base-pair changes. Previously unknown and even complex sequence variations can be readily detected and characterized in a robust and straightforward way. The rotary design of the Rotor-Gene Q and its outstanding thermal and optical performance are highly suited to HRM.
The HRM option for the Rotor-Gene Q includes:
- A specially tuned high-intensity optical HRM channel
- Thermal resolution of 0.02°C
- High data-acquisition rates
- Comprehensive HRM software
Minimum maintenance; maximum convenience
The Rotor-Gene Q is engineered to reduce the need for maintenance and to maximize ease of use. This saves time and costs, and allows you to focus on your research; not on keeping the cycler up and running.
Convenient features of the Rotor-Gene Q include:
- Lifetime guarantee on highly stable LEDs, no expensive lamps or lasers to change, no gradual performance loss of light source
- No optical calibration needed at installation or when the instrument is moved
- No sample block to clean
- No condensation or bubbles in reactions due to rotation
- Small, light, and robust; simply place the instrument wherever you like
