UV Decontamination of Lab Equipment


Decontamination of Lab Equipment using Ultraviolet LED

Problem: Keeping laboratory equipment clean is a daunting task. Microbes from the air, lingering in places like cardboard boxes, or coming from human skin can threaten the validity of your results. At the same time, costly cleaning procedures threaten research time and productivity. To eliminate RNase A, for example, decontamination procedures range from chemical detergents to rinsing with RNase-free water and autoclaving for hours, both of which cost time and money. Effectively decontaminating equipment at a low operational cost is a constant battle in the lab.

Solution: Phoseon Technology’s solid-state, deep UV LEDs save time and money, and preserve the accuracy of your results through thorough decontamination. Patented SLM™ technology allows Phoseon lamps to generate orders of magnitude higher irradiance than is currently seen in the market. This high-irradiance light is then focused to a specific wavelength, or combination of wavelengths, that affect the structure of microbial contaminants.

When it comes to inactivation, irradiance matters. Studies have shown that high irradiance 275 nm light requires a lower total dose, less time, and more completely inactivates glass surfaces compared with lower irradiance. Complete inactivation of RNase A was achieved after 5 minutes at high irradiance compared with 25 minutes for the lower irradiance level.
