How it Works
Rethink Photochemistry. The Reactor is Now Wireless and Inside.
Wireless Power Transfer
Traditional immersion lamps require vessel adapters and cables. We get rid of adapters and cut the cord. Using a proprietary wireless power transfer technology, the Photonic Stir Bar receives continuous, stable power. How does it work exactly? – Stay tuned and expect a surprise.
Zero-Interface Logic
The integrated smart controller automatically detects the wireless power transmission and operational parameters. No external interfaces to program, no touch screens to contaminate. Just drop it in, put it on your stirrer, and the reaction begins.
Maximized Photon Efficiency
External lamps lose up to 99% of their energy to poor surface area exposure, reflection, and glass walls. By bringing high-flux LED emitters directly inside the reaction mixture, we bypass these obstacles. The result? 200 mW of internal light matching the speed of a 30-40 W external lamp.

Frequently Asked Questions
Which reaction vessels are compatible?
The Photonic Stir Bar is designed for versatility. It fits effortlessly into standard 10 mL to 20 mL headspace vials, Schlenk tubes, and flat-bottom flasks, and even opaque (amber) vessels. Because the light source is inside, the optical properties of the vessel no longer interfere with your setup.
Does it withstand aggressive solvents and reagents?
Yes. The internal electronics are completely encapsulated in a highly resistant fluoropolymer shell (FEP). It is built to endure the harshest chemical environments and extreme pH values commonly found in organic synthesis.
Available Wavelengths?
Besides 450 nm and 365 nm, we are ready to implement many other wavelengths available as LED emitters. – Contact us for details!
How will the Wireless Power Transmitter look like?
This is part of our proprietary, “special IP sauce”, so we can´t tell you at the moment. Stay tuned for the reveal and be prepared for a surprise !
Does it work with highly concentrated or dark reaction mixtures?
Yes. In opaque mixtures, external light typically penetrates only a fraction of a millimeter. The Photonic Stir Bar changes this paradigm: by emitting light directly from the center of the stirring vortex—the point of maximum turbulence and mass transfer—it continuously irradiates fresh reagents. For our Batch 1 early adopters, this presents a unique opportunity: We actively invite you to leverage this effect, push the boundaries of photochemistry, and explore reactions in dark or highly concentrated media.
Does the setup require additional fan cooling?
Because of its high photonic efficiency, the Photonic Stir Bar produces only negligible heat, so external fans (as required with external lamp setups) are generally not required.
What environment temperatures are compatible?
The Photonic Stir Bar is designed for a temperature range of -20°C to +80°C.
Can it be used inside glove boxes?
Yes, absolutely. Because the device is completely wireless, there are no cables to thread through airlocks. The fully encapsulated design is vacuum-safe for standard antechamber cycling. (Note: Please do not heat the device in a drying oven prior to transfer; simply wipe with a dry solvent at room temperature).
How do I clean the device? Is there a risk of cross-contamination?
You can clean it exactly like your conventional stir bars with one exception: sonication. Thanks to the non-porous FEP encapsulation, it is fully compatible with standard solvent washing and typical acid/base baths, ensuring zero cross-contamination between your runs.
What is the lifespan of the device?
The Photonic Stir Bar is a durable piece of lab equipment, not a single-use device. Because it has a durable fluoropolymer shell and is not requiring any batteries, it is ready to provide thousands of hours of reliable operation.
