TI-24 UV Transilluminator (College Model, 254 nm / 365 nm) — Apex Labs

The Apex Labs TI-24 UV Transilluminator (College Model) is an essential molecular biology imaging instrument designed for genetics, biotechnology, clinical diagnostics, and university research laboratories. Engineered to provide high-intensity, uniform ultraviolet excitation, this instrument enables rapid visualization, documentation, and preparative excision of fluorescently labeled nucleic acid bands (DNA/RNA) and proteins in agarose or polyacrylamide gel matrices. Powered by an internal array of eight high-efficiency UV tubes operating at dual switchable wavelengths — 254 nm for maximum fluorophore sensitivity and 365 nm for non-destructive gel band isolation — the TI-24 features a spacious 210 × 210 mm viewing stage and high detection sensitivity capable of resolving fragments down to 50 ng.

Performance Highlights

• Dual Wavelength Versatility: Shortwave 254 nm mode delivers intense excitation for faint nucleic acid band detection, while longwave 365 nm mode minimizes DNA photo-nicking during preparative gel excision.
• Uniform 8-Tube Illumination Engine: Advanced optical diffusion geometry eliminates shadow zones and hot spots, guaranteeing uniform background brightness across the entire 210 × 210 mm stage.
• High Sensitivity Resolution: Detects down to 50 ng of nucleic acids, allowing clear visual identification of low-concentration PCR amplifications and restriction enzyme digests.
• Ergonomic Safety Design: Adjustable, transparent orange UV-blocking screen protects users from harmful UV-A/UV-C radiation without obscuring band alignment during gel excision.

Primary Sector Applications
