Versatile high resolution gel doc

An entry level system for imaging fluorescence and visible applications, the G:BOX F3LFB gel doc is the ideal solution for your laboratory.

Using your choice of dyes or stains, the G:BOX F3LFB automatically selects the right lighting and filters to detect close bands on both small and large gels. Choosing white light options for Coomassie Blue, UV and blue lighting options, ethidium bromide or SYBR® Safe gels, this system is the ultimate in gel doc flexibility.

The stylish and modular designed G:BOX F3LFB gel doc system includes a high resolution 5m pixel camera which is capable of giving outstanding images with incredible spatial resolution as well as a motor driven zoom lens and a motor driven filter wheel and feedback lens, allowing you to optimise your image capture using user protocols.

The system is controlled by GeneSys application driven image capture software and comes complete with unlimited copies of GeneTools analysis software.

Syngene offers a range of UV transilluminators suitable for all your imaging needs. Transilluminators are available in 230V 50Hz, 230V 60Hz (-E60), 115V 60Hz (-A), 115V 60Hz (-ACA) and 100V 50/60Hz (-J). Available wavelengths are short wave (254nm, 2020S or 2530S), medium wave (302nm, 2020M or 2530M) and long wave (365nm, 2020L or 2530L).

UltraBright-LED transilluminator

Blue light transilluminators are often used as an alternative to a UV transilluminator when users wish to use ‘safe dyes’ instead of Ethidium Bromide. A blue light transilluminator is a ‘safe’ light source, in that the user is not exposed to harmful UV radiation and samples are free from photonicking. The UltraBright-LED transilluminator can be used instead of the UV transilluminator in all Syngene G:BOX systems.

UltraBright-LED transilluminator can be used with gels up to 20 x 16cm for use in the G:BOX series. This model uses side mounted 470nm LED arrays for illumination.

UV-blue light converter screens

These come in two sizes 21cm x 26cm and 25cm x 30cm and are used to change harmful UV into blue light. They are made of scratch resistant plastic and are easy to retrofit onto a UV transilluminator.

Visible light converter screens

These come in two sizes 30.5cm x 33cm and 23.5cm x 30cm and are used to change UV light into visible light, ideal for imaging Coomassie Blue and Silver Stained gels.


The EPI UV module can be fitted to any G:BOX darkroom (those produced after July 2010). The module fits above the standard LED white light module which is standard on all G:BOX systems. The EPI UV module can have either a 254nm, 365nm or 302nm tube. Either one or two modules can be fitted to each darkroom.


The filter wheel takes the 72mm range of filters.
