Key Applications & Uses
- Routine immunofluorescence (IF) and immunocytochemistry — detection of antigens, antibodies, cytoskeletal elements, and cellular markers in fixed cells, tissue sections, and smears.
- Clinical pathology & diagnostic labs — fluorescent staining for infectious agents (e.g., TB, malaria, viral inclusions), autoimmune markers, tumor diagnostics, and rapid screening protocols.
- University & teaching laboratories — advanced student practicals in cell biology, microbiology, immunology, histology, and fluorescence techniques using common fluorophores.
- Biotech & pharma R&D — cell-based assays, reporter gene expression (GFP), apoptosis/necrosis detection, receptor localization, and basic multi-color labeling studies.
- Combined brightfield + fluorescence observation — correlated morphological analysis and fluorescent signal localization on the same specimen.
- Digital documentation — trinocular port for attaching cameras to capture high-quality fluorescence and brightfield images for reports, publications, and presentations.
Why Choose from G-Hexa?
- Semi-apochromatic optical excellence — Infinity plan semi-apo objectives provide significantly better color correction, higher resolution, and brighter fluorescence transmission than standard achromats, especially in the green and blue ranges.
- Integrated, maintenance-free LED fluorescence — 5W disc LED delivers instant-on, stable, cool illumination with no warm-up, no hazardous mercury disposal, and extremely long service life — safer and more economical for daily use.
- User-friendly & ergonomic design — Rackless stage prevents slide damage, swing-out condenser allows quick objective switching, wide 22 mm field of view reduces eye strain, and low-position controls enhance comfort during long sessions.
- Powerful halogen transmitted light — 6V/30W Koehler halogen offers warm, natural color rendering and high intensity for demanding brightfield applications alongside fluorescence.
- Quintuple nosepiece flexibility — Extra position allows future addition of specialized objectives (e.g., 60× dry, phase, or DIC) without swapping turrets.
- G-Hexa trusted quality — Competitive pricing for semi-apo fluorescence performance, backed by expert technical support, 1-year warranty, fast delivery from Pune stock, and upgrade options (UV/DAPI filters, LED upgrades, cameras) to match evolving lab needs.
Frequently Asked Questions (FAQs)
Q: Which fluorophores work best with the B and G channels on GHEXA-16.2603-L-T2? A: B (Blue) is optimized for FITC, Alexa Fluor 488, GFP, and similar green emitters; G (Green) supports TRITC, Cy3, Rhodamine, Texas Red, and related red-shifted dyes. UV/DAPI requires an optional filter cube.
Q: How does the semi-apo objective set improve fluorescence imaging? A: Semi-apochromatic correction reduces chromatic aberration across a wider wavelength range, resulting in sharper, brighter, and more accurate fluorescence signals with less color fringing compared to standard achromatic objectives.
Q: Is the fluorescence LED brighter than traditional mercury lamps? A: The 5W disc LED provides excellent intensity for routine FITC/TRITC work with instant operation, no alignment, and no bulb replacement for years. It may have slightly lower peak UV output than mercury (UV channel optional).
Q: Can I perform phase contrast or DIC on this model? A: The quintuple nosepiece and swing-out condenser support easy addition of phase contrast sliders/objectives or DIC prisms/inserts as upgrades — contact G-Hexa for compatible kits.
Q: How do I connect a digital camera? A: The trinocular head features a dedicated phototube (usually 23.2 mm or C-mount ready). Use a 0.5× or 1× C-mount adapter based on your camera sensor size — G-Hexa offers recommended camera packages.
Q: What is the advantage of the rackless stage? A: The rackless design eliminates protruding gear racks, preventing accidental damage to slides or fingers, while providing smooth, precise movement and a cleaner appearance suitable for shared lab environments.
