GE ImageQuant LAS-4000 Multi-Mode Luminescent Imager for Gel and Membrane Analysis

The GE ImageQuant LAS-4000 Multi-Mode Imager is a versatile luminescent image analyzer designed for sensitive digital imaging of gels, membranes, and films in molecular biology and biotechnology research. Ideal for chemiluminescence detection, UV fluorescence analysis, and biomolecular imaging, it supports a wide range of bioprocessing and molecular diagnostics workflows.

Key technical features include:

• High-sensitivity F0.85 43 mm lens with a large 21 × 14 cm field of view capturing images at 6.3-megapixel resolution through an innovative diagonal pixel configuration
• Cooled CCD camera operating down to -25°C (max -35°C) providing extended exposure times up to 30 hours with reduced background noise, essential for quantifying weak signals in biopharmaceutical production pipelines
• Wide dynamic range spanning four orders of magnitude, enabling precise quantitation of weak and strong signals without multiple film exposures
• Flexible automatic and manual capture modes including incremental, repetitive, and programmed exposure sequences, enhancing control for fluorescence and chemiluminescence imaging
• Modular design featuring a dark box, high sensitivity lens, cooled camera, and five-position filter wheel allowing quick switching of lighting conditions using epi or trans illumination setups
• Integration of shading correction and image quality enhancement software with binning options (1×2, 2×4, 4×8, 8×16) for optimized image clarity
• Remote automatic focusing and iris control for streamlined operation without opening the cabinet

This system is widely used in synthetic biology research, molecular cloning, and clinical diagnostics environments requiring robust quantitative imaging of fluorescent and chemiluminescent assays. Users should note that an EPI trans tray (sold separately) is required for optimal use of Epi White illumination.

The ImageQuant LAS-4000 supports USB 2.0 interface for data transfer and operates within environmental conditions of 15°C to 28°C and 30% to 70% relative humidity without condensation. The unit measures 21×20×35 inches and weighs 150 lbs, powered by 100-240V, 50/60Hz electrical input.

This biomolecular imager is critical in live-cell imaging, fluorescence analysis, and gene editing applications, making it a trusted tool among researchers focusing on molecular diagnostics and biomanufacturing.
