Enabling Reliable UVA Modeling: LUYOR-3550 UV Irradiation Chamber at Jiyan Cosmetics

Jiyan Cosmetics, a subsidiary of Yatsen Beauty Group, recently adopted the LUYOR-3550 UV Irradiation Chamber for UVA irradiation modeling in human skin fibroblasts. Their research required a relatively high dose of 15 J/cm², and with its high UV intensity, the LUYOR-3550 delivered this dose within the desired 30-minute exposure window.

LUYOR-3550 UV Irradiation Chamber

The LUYOR-3550 UV Irradiation Chamber is a medium-sized, robust, and complete UV irradiation system designed for time- or dose-controlled sample exposure. It supports one or two spectral ranges—UVA, UVB, or UVC—and features a built-in sensor that maintains a consistent UV dose regardless of lamp aging, contamination, or temperature fluctuations.

With stable UV output and multi-wavelength options, the LUYOR-3550 is ideal for a wide range of ultraviolet-based research:

Irradiation of bacteria and cell cultures
Irradiation of animals (mice, rats, guinea pigs, rabbits, etc.)
Photostability testing
UV and daylight materials testing
UV curing, sealing, and bonding
UV aging testing
UVC disinfection
