This device uses high-performance ultraviolet light-emitting diodes (UV-LEDs) as the excitation light source, replacing traditional mercury UV lamps. It offers advantages such as long lifespan, rapid start-up, and high energy efficiency. Moreover, it contains no mercury or other harmful heavy metals, making it safer for both users and the environment. Its unique backlit illumination design combines three UV wavelengths: 302 nm, 365 nm, and high-power 300 nm, to deliver uniform and adjustable excitation light. This allows flexible adaptation to various fluorescent dyes, chemical stains, and sample conditions, meeting diverse experimental needs.

The device features a compact and durable body with three-level brightness adjustment, light shielding, and safety power cut-off functions, enhancing experimental sensitivity, operational convenience, and user safety. When used with a miniDarkroom, observation efficiency is further improved, and image capture can be completed quickly. As this device is specifically designed for the qualitative observation and quantitative analysis for both nucleic acids and proteins, it is widely applicable in molecular biology, proteomics, clinical research, and educational laboratories, which makes it an essential piece of device in modern life science research.

 Triple-Wavelength UV Design (365 nm / 302 nm / 300 nm)

Wide application range suitable for fundamental life sciences, medical diagnostics, molecular biology, and related research fields.

 Magnetic Lid Design

Utilizes a hinge-free magnetic attachment structure for easy, safe, and durable operation. Equipped with a UV-Shielding Cover that enables direct sample observation, gel cutting, and photography while preventing biological damage.

 Auto Power-Off When Lid Is Detached

The device will automatically shut down if the UV-Shielding Cover is not properly installed, preventing accidental UV leakage and enhancing operational safety.

 Auto Shut-Off Function

To protect the device and prevent potential risks caused by oversight, this product is equipped with an auto shut-off feature.

• 365 nm / 302 nm Modes: Automatically shuts off after 5 minutes of operation.

• High-Power 300 nm Mode: Automatically shuts off after 7 minutes of operation.

 Bottom-Illuminated LED Design

The system is equipped with long-lasting, maintenance-free, bottom-embedded LEDs, eliminating the need for tube replacement and the risk of harmful gas emissions. The bottom-up lighting design significantly reduces refraction and diffraction commonly associated with side lighting, thereby enhancing image clarity and photography quality.

 Three-Level Brightness Adjustment

Brightness levels can be adjusted based on sample concentration or observation requirements by pressing the brightness button (as shown in the image below) when operating in the 302 nm or 365 nm wavelength modes. This function is not available in the 300 nm high-power wavelength mode. Brightness adjustment ensures optimal image contrast and viewing quality.

 Durable and Lightweight for Versatile Use

The alloy housing provides a balance of stability and portability. Its compact and durable design makes it suitable for both laboratory use and field applications.
