Product Description
GE Healthcare ImageQuant LAS 4000 Luminscent Image Analyzer
**This instrument has only been tested for basic power function. This item has slight visible scratches on bottom front panel and side of unit from normal use. Does NOT include ImageQuant Software. See pictures for further details. This unit will need software and calibration by buyer.
The GE ImageQuant LAS-4000 Multi-Mode Imager is a robust digital imaging system of gel or membrane samples or films. This imaging system uses epi or tans light on gels stained by EtBr and exposes a sample repeatedly, incrementally, or by programming exposure schemes. This flexible system is modular and can use a combination of light sources and filters to achieve the technique you need, including upgrading to an IR fluorescence capability, available from GE.
The wide linear dynamic range of the LAS-4000 avoids multiple film exposures by accurately quantitating both weak and strong signals over 4 orders of magnitude. The F0.85 43 mm LAS high sensitivity lens of this quantitative biomolecular imager has a 21 Г— 14 cm field of view with a 6.3-megapixel image resolution thanks to the innovative diagonal pixel configuration. This camera is cooled to -25В°C (maximum -35В°C) allowing users longer exposure times so theres less background and yielding more precise quantitation of weak signals.
The GE ImageQuant LAS-4000 Multi-Mode Imager is capable of Quantitative Western blotting, UV fluorescence, and Infrared fluorescence when used with the right reagents, optional colored epi illuminators, and filters installed. This system is comprised of a dark box, camera, lens, and a five-position filter wheel that gives users the flexibility to change methods. To control this system the robust ImageQuant LAS 4000 software easily guides users through programming Focusing, filters, illuminators, and exposure time without needing to open the cabinet. The automated iris of this imaging system responds quickly to changes in focus and other settings for quick turnaround.
