Non-Invasive 6 logs Sterilization by

Intense Pulsed UV Light

The Editor’ s Choice
Its effectiveness increases with the UV pulse power in w / cm ² to a sample from equal to the one of continuous wave UVC light and up to the PUVD region:
only at PUVD bacteria & spores are fully physically disintegrated, as per the chart and photo on the left.
Wek-tec was first to publish these results in 1999-2001 and ever since works in this spectral region, not yet adapted by most of our competition.
Baxter Corp.( USA) back in 2013 independently proved it with our standard R & D system as below by disintegrating UV resistant spores of B. Pumilos in transparent infusion bags at acceptable rates of 7 to 9 pulses, to be delivered in 3s on lines.
