Gel.ProCCD gel documentation system
CCD 16-bit Gel Documentation System 16-bit CCD sensor gel doc system

Sharp zoom lens coupled to a highly sensitive 16-bit Sony scientific grade CCD camera, the Gel.ProCCD gel documentation system, is a high quality, yet low cost professional gel and bio-imaging system. From agarose, PAGE, western blots, dot blots, nucleic acid, colorimetric to fluorescent imaging and upgradeable to chemiluminescence; this gel system has all the options.

Featuring high resolution extremely sensitive scientific grade CCD camera (with choice of 1.4, 5.6 and 9 megapixel cameras) with extremely low noise and dynamic flat field calibration coupled to a motorized zoom lens (with an option for numerical feedback value) that is pre-focussed for different zooms or sample setting, mounted in an enclosure that covers and protects the camera and lens from dust and mold. The camera, lens and cabinet connects to and can be controlled from the PC using the live-view acquisition capture software.

Choice of illumination options with long-life UV trans/epi lighting, wavelength-specific LEDs and more, add to the versatility of the system. UV roll-out transilluminator can be provided in single, dual 302-312nm and 365nm (additionally 254nm, for triple wavelength configuration), and even Red, Green, Blue LEDs ranges. Large filter size of transilluminator for gel images up to 21x26cm, with extra large special filter size of up to 26x26cm also is available.

Colorimetric samples up to 38x30cm can be captured. Epi-white light illumination from above is standard using two LED tubes. Optionally, ultraviolet epiillumination in a variety of wavelengths (254/312/365nm) can also be provided. UV to white light and UV to blue light trans converter screens are also available. UV tubes and LED lamps are high-quality, long-life tubes and lamps, with the latter lasting for more than 40,000 hours of usage (under proper usage with flicker-less, stabilized power supply). Reflectors are standard for uniform light distribution.

The mild & stainless steel, epoxy coated microprocessor controlled dark room cabinet has features for UV irradiation safety switch that switches off the UV lights as soon as the door is opened. Additionally, a timer is provided that switches off UV in case the user forgets to shut it off. Option to adjust timer for excision. Also, the user can opt for automatic switching on of the Dual Epi-White LEDs on opening of door and for automatic controls of UV light and exposure. A transilluminator cooling system is also provided to prevent overheating of gels. Optionally, a window and access door can be provided for gel observation and cutting. And, a gel platform temperature control
(<34 C) can be provided. Gel alignment templates also available.

Gel.ProCCD gel documentation systems are now CE marked and made in an ISO9001:2008 certified facility.
These are high quality products, proudly made in India.
How the Gel Documentation System works

A transilluminator is mounted on roll-out rails inside a light-tight cabinet. To place the gel, the door is opened and transilluminator pulled out. Push it in, close the door and switch on the UV light and camera. The camera is mounted on top of the cabinet along with zoom lens and wavelenght filter (nominally 590nm filter suitable for Ethidium Bromide EtBr gels is provided)..

Connect the camera to the PC using the USB cable and gel capture software, to get a real-time live view image of the gel. Adjust camera settings (like shutter speed, aperture, focus) till the optimum image is obtained. Click your images and save them on the PC. A white light epi-illuminations source is also provided, that illuminates objects from top.

With the 1D gel analysis software, you can analyse the gels.
