XDive Instrument

Sponsored by the NIH RADx program, Star Array and OnsiteGene have jointly developed a series of superfast real-time PCR machines and related reagents. Our XDive superfast real-time PCR system completes 40 PCR cycles with real-time imaging in as little as 5 minutes. It completes 40 cycle multiplex low-copy DNA testing in 7 minutes, and low-copy multiplex RNA testing in 9 minutes, at the same detection sensitivity as that on a leading brand qPCR machine performing the same assay in 45 minutes. XDive instrument has obtained FDA EUA authorization for CoVID-19, safety and EMC certification from TUV Rheinland.

We have a full-fledged multidisciplinary engineering, software, and reagent development team to readily develop new design and applications for our customers. Additionally, the RUO device performing superfast PCR and qPCR can now be supplied to collaborators.


XDive™ superfast real-time PCR system offers state-of-the art technology, user-friendly software, and affordable superfast PCR consumables and reagents. Unlike a traditional PCR system, XDive™ uses a unique patented thermal cycling technology utilizing Artificial Intelligence that can not only achieve ultra-fast heating and cooling but also achieve high precision at target temperatures required for PCR. Integrating superfast thermal cycling, superfast fluorescent imaging, and medium throughput design, our system is the fastest and most flexible of its kind - with the capability of completing a 40-cycle multiplex qPCR run in just 5-7 minutes with real-time fluorescent imaging. It possesses the following unique features:

1.    Superfast thermal cycling with precise temperature control


The instrument contains proprietary thermal blocks with liquid metal material to quickly and evenly raise or lower the reaction temperature at the ramping rate of 67°C/s for heating and 82°C/s for cooling. The reaction temperature is precisely controlled in thermal blocks by premium sensors for best accuracy and reproducibility.

2. Superfast fluorescent imaging with multiplexing capability

The fluorescent signal excitation and detection are conducted by a LED light source and 4 dye filters in the optical detection chamber for multiplex analysis. Images of all samples and channels can be scanned in a couple of seconds. The optical system is upgradable to 6 channels to increase the multiplexing capability.
