SmartDoc™ 2.0 Imaging System

• Imaging enclosure works with all common smartphones
• System includes blue light illumination base, orange viewing cover, and orange photo filter
• Ideal for common safe stains (SmartGlow™, SYBR Green, GelGreen™, etc.)
• Visible blue light will not damage DNA
• Gel viewing and gel access for DNA band cutting
• Optional amber viewing glasses, for band excising
• Imaging enclosure can also be used on existing transilluminators

Introducing the SmartDoc™ 2.0 (Item no. E5001-SDB). This complete system has been developed for safely viewing nucleic acids in agarose gels and for capturing quality digital images with a smartphone camera.  Blue light is used instead of UV, which is safer for lab personnel and will not damage DNA samples.

The SmartDoc™ Imaging Enclosure can also be purchased separately (item no. E5000-SD) without the blue light illumination base.  The enclosure by itself can be used on most existing UV transilluminators or blue light transilluminators for smart phone imaging.

The illumination base emits an intense blue light with a peak output of 460 nm for optimum excitation of nucleic acids stained with green fluorescent dyes (SYBR® Green, SmartGlow™, GelStar™, GelGreen™, etc). The orange cover fits on top of the illumination base and acts as a filter to absorb blue light, allowing visualization of the fluorescing samples. The cover can also be set at an angle for gel access and cutting out DNA bands for further study.

The SmartDoc™ imaging enclosure includes an orange photo filter for photography of the gels with a smartphone. An extending adapter can be inserted for full dimension imaging of gels up to 15 x 15 cm or removed for close-up pictures. The enclosure can also be used directly on any other existing UV or blue light transilluminator.  Additional filters are available for imaging gels on a UV transilluminator.  Please see our “Filter and User Guide” to show which filter is best for different imaging applications.

Optional SmartBlue™ Plus Viewing Glasses

Accuris SmartBlue™ Plus Viewing Glasses offer exceptional protection for researchers working with bright blue LED and UV light illuminators. The polycarbonate filter lenses are shatter proof, scratch resistant and block light in the UV (280 nm) to blue (490 nm) wavelengths. In addition, they are compliant with ANSI Z87.1.

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. 

*Always wear appropriate UV protection for eyes and exposed skin when working with UV light sources.
