Excelitas Unveils X-Cite TETREM LED Light Source for Fluorescence Microscopy

 Excelitas has launched the X-Cite TETREM—a four-channel, switchable light guide-coupled LED light source designed to optimize fluorescence microscopy workflows.

The X-Cite TETREM uses Excelitas’ new smartDIAL control interface, enabling researchers to intuitively and easily control multiple channels manually through an easy-to-read display featuring advanced controls. Offering high power for routine imaging applications, TETREM is an accessible, budget-friendly solution for fluorescence microscopy laboratories.

Key features of the X-Cite TETREM include:

• Fluorophore Excitation: Available in two models, XT640S (365nm DAPI excitation) and XT640L (385nm DAPI excitation), TETREM supports DAPI, FITC, TRITC/mCherry and Cy5 fluorophore excitation.
• Independent Channel Control: Four individually or simultaneously controllable channels for on/off and intensity adjustments.
• Enhanced Filtering: Features a filter holder for fine-tuning excitation between 500 nm – 600 nm.
• Flexible Connectivity: Control via smartDIAL, USB or TTL inputs.
• Microscope Compatibility: Liquid light guide coupling ensures seamless integration with a wide range of microscope systems.
• Compact Design: Ideal for laboratories with limited space or where direct coupling is impractical.

“We are thrilled to introduce the X-Cite TETREM, which brings intuitive channel control and high-performance fluorescence illumination to labs seeking a cost-effective solution,” Excelitas Senior Product Manager Michelle Gal said. “This latest X-Cite solution upholds our commitment to providing reliable, high-quality LED fluorescence illumination systems for microscopy applications. In addition to delivering precision, versatility and value, X-Cite TETREM simplifies individual channel control, excites the most common fluorophores and offers an accessible alternative to high-end illumination systems for a variety of routine fluorescence imaging applications.”

From advanced live-cell imaging to routine laboratory use, Excelitas’ X-Cite products range from advanced, high-end LED illuminators with intelligent triggering and pulsing capabilities for live-cell imaging to budget-friendly options such as the new X-Cite TETREM.
