Spectroline Longlife Filter Ultraviolet 254 nm Short Wave 365 nm Long Wave

Spectroline ENF-260C/FE Handheld UV Lamp – Dual 254 nm Short Wave & 365 nm Long Wave

The Spectroline ENF-260C/FE is a versatile, laboratory-grade handheld ultraviolet lamp engineered for applications requiring both short-wave 254 nm and long-wave 365 nm UV illumination. Featuring a specialized Longlife™ filter glass, this unit minimizes solarization and maximizes UV transmittance over extended periods. This dual-wavelength capability makes it an essential tool for analytical TLC plates, molecular biology imaging, forensic visualization, and mineral fluorescence inspection.

Technical Performance & Design

• Dual-Wavelength Flexibility: Equipped with separate 6 watt tubes for 254 nm short-wave UV** (ideal for photochemical reactions and DNA/RNA viewing) and 365 nm long-wave UV** (optimized for fluorescence analysis).
• Longlife™ Filter Technology: Integrated with a premium filter window that resists aging, scratching, and clouding, ensuring consistent, high-intensity UV output with minimal visible light transmission.
• Independent Tube Control: Features a convenient multi-position toggle switch allowing operators to alternate seamlessly between wavelengths or run them individually to prevent sample overexposure.
• Ergonomic & Portable Housing: Built with a lightweight, high-impact polymer chassis designed for easy benchtop handling, and is fully compatible with Spectroline workstations for enclosed darkroom viewing.
