About PureFize®

Fast, safe and efficient UVC disinfection

PureFize® is a totally mercury-free UVC disinfection technology that builds on the principle of field emission in a nanostructured environment. It creates a perfect germicidal light spectrum that quickly destroys bacteria, viruses and other germs beyond repair. Thanks to reduced thermal heating, the PureFize light sources can easily be integrated into any design.

Huge market potential for disinfection

The outbreak of COVID-19 has brought unprecedented challenges to the world and chances are our new customs, such as frequent handwashing and cleaning, are here to stay. According to a report by Accenture, people are permanently changing personal habits such as cleaning surfaces. At the same time, 40% of consumers don’t think that product manufacturers have responded well enough to this new living situation. Accenture believes that there is a big opportunity for manufacturers to get ahead and develop new solutions that will help people keep their belongings clean and stay safe.

PureFize – germicidal UVC at its best

UV disinfection is a physical process that does not include the use of any chemicals or generate large amounts of waste. It is fully sustainable, fast and efficient on all kinds of microorganisms. That is why UV light has a great potential to become one of our most essential resources in the battle against infection.

LightLab’s UVC disinfection technology is called PureFize. PureFize is 100% mercury-free and builds on the principle of field emission in a nanostructured environment.

Field emission is discharge of electrons from the surface of a material due to the presence of an electric field. The electrons strike the inside of a lamp glass coated with light powder (luminescent layer) and a very thin conductive layer, creating light. The properties of the light, such as wavelength, are controlled by the light powder.

The perfect spectrum

PureFize creates UVC light with a perfect germicidal spectrum. The spectrum is broad with a peak wavelength at 262 nm, which is when germs best absorb UV light.*

Exceptionally high degrees of germicidal reduction (log8=99.999999%) can be reached very rapidly. Also, the scope of the spectrum (as seen in the diagram) prevents any reactivation, which means that all bacteria, viruses and other germs are destroyed beyond repair. Read more about germicidal reduction

This is how PureFize works. The box is only an example of how our technology can be integrated into a product.

Other benefits of PureFize

Environmentally friendly
PureFize light sources contain no mercury. No materials or substances harmful to the environment are used during manufacturing. The light sources have long lifespan and the entire system can be treated just like ordinary electronic waste.

Minimized thermal heating
The optimized geometrical design of PureFize light sources in combination with their ability to operate fully over a wide temperature range eliminates the need for thermal management.

Wide working temperature
PureFize yields a consistent irradiation output in a wide temperature range – from -20 to +100°C. This makes it very reliable as outer conditions (heat or cold) or small confined areas that easily overheat do not jeopardize the result. You can always be 100 % sure that the item is properly disinfected.

Freedom of design

Since the need for thermal management is minimized, you can integrate PureFize into practically any design. Rather than designing your products around a disinfection solution, you can design your products with the disinfection solution.

Instant on/off
Some UVC-technologies require a warm-up and cool-off time, whereas PureFize emits high-intensity light as soon as it is turned on and stops instantly. This makes it suitable for applications that require frequent or instant disinfection.

Plug and play
The PureFize component kit comes with the light source and driver facilitating integration. No additional components are needed, just plug and play.

Ready for volume production
PureFize is designed for high-volume production. The relatively low investments for setting up large scale manufacturing provide low cost benefits.
