Li LAC 545056 Microphone Disinfector
safe/simple/fast
Professional disinfection through controlled exposure to ultraviolet light (UV-C).
Simple
Li.LAC resembles a futuristic sandwich grill in a robust, road-ready 19” 3U
rackmount format. Simply place the microphones on the stainless-steel grille,
close the irradiation chamber, and press start. The steel grille can
accommodate up to three handheld mics or handheld transmitters. It is also
possible to disinfect other items like headsets, lavalier microphones, etc.
Fast
A disinfection cycle takes only 5 to 10 minutes. Additional 2 minutes of pre-
heat time might apply for cold UV-C lamps.

Proof of effectiveness and clinical validation
A disinfection level of 99.99%* for surface disinfection inside Li.LAC has
been approved by the independent, accredited laboratory Opsytec Dr. Gröbel
GmbH.
The departments of Biomedical Engineering and Medical Microbiology & Infection Prevention of the University Medical Center Groningen (UMCG) have conducted comprehensive scientific studies to evaluate the effectiveness of Li.LAC. Viruses were sprayed onto microphones, similar to singing into the mic. The results show a reduction of 99.3% of the viral load on strongly contaminated microphones (including the metal grille and foam underneath) after 10 minutes of irradiation inside Li.LAC. * The exact disinfection level varies with the type of virus or bacteria and with the shape and the surface of the object to be disinfected. ** Industry standard vocal microphones were used for this study.

Microphone and material compatibility
Any kind of intense cleaning procedure (soap & water, alcohol or UVC light)
has a long-term effect on the materials used in or on microphones. Different
kinds of plastics and the outer appearance (color/ gloss) especially, can be
altered or degraded by “too much cleaning”. We have run numerous tests with
various microphones inside Li.LAC to evaluate the long-time impact of UV-C
light.
The results show that the aging effect is implied by UV-C disinfection inside Li.LAC is negligible compared to the normal aging that happens to microphones (by mechanical impacts, dirt, humidity, etc.). During the long-term irradiation tests in Li.LAC, we recorded changes in the appearance and frequency response of the microphones after 500, 1000, and 1500 disinfection cycles. 1500 cycles correspond to several years in the real life of a microphone.
