SmartBlue Plus Viewing Glasses offer exceptional protection for researchers working with bright blue LED and UV light illuminators. The polycarbonate filter lenses are shatterproof, scratch-resistant, and block light in the UV (280nm) to blue (490nm) wavelengths. These glasses are ideal for general protection when working with hazardous wavelengths and for precision DNA band cutting on a UV or blue light transilluminator. While blocking hazardous UV and blue light, the glasses allow clear visualization of DNA bands stained with Ethidium Bromide, SmartGlow™, SYBR Green, and other fluorescent dyes.
