NK Flash 250 – light curing agent with high capacity and control

NK Flash 250 light curing device with high capacity and control available from May 2025

The NK Flash 250 is a light curing unit designed for maximum productivity and optimal control when curing virtually all 3D resins and light-curing composites available on the market. Featuring advanced stroboscopic light technology, nitrogen connectivity, and an extra-large curing chamber, this unit is perfectly suited for applications where speed, scale, and precision come together.

The NK Flash 250 delivers fast and reliable results, with a curing time of less than 7 minutes* for complete sets of splints, trays, guards, and surgical guides. Thanks to the adjustable flash frequency, which goes beyond the standard 10 Hz, curing times can be reduced by up to 50%. This is ideal for those aiming for maximum efficiency. All program data is automatically stored and can be easily downloaded, simplifying compliance with process validation requirements. The NK Flash 250 is equipped with robust, replaceable steel components, ensuring a long service life and easy maintenance.

The NK Flash® 250 light curing unit is specially designed for high throughput. The extra-large curing chamber provides more than four times the surface area and 60% more height than the Otoflash, allowing larger or multiple pieces to fit effortlessly. With adjustable curing programs and the ability to save favorite settings, you can work quickly and consistently. The intuitive controls make the device perfectly suited for use in intensive work environments.

*Always follow resin/composite manufacturer guidelines and refer to device instructions to ensure proper curing results. Results and times may vary depending on resins/composites used and curing conditions (e.g., condition of curing trays, etc.)

Advanced Technology

• Stroboscopic light spectrum: (250 – 950 nm) with high intensity for deep and uniform curing.
• 360° light distribution: The 360° light distribution ensures that the pieces do not need to be rotated in the curing unit.
• Nitrogen compatibility: The NK Flash® 150 features a nitrogen connection, which helps achieve a smoother surface and reduces post-processing.
• Compatible with all 3D resins and light-curing composites: The NK Flash® 150 works with virtually all available materials.
