HAND-HELD UV TRANSILLUMINATOR
A Hand-Held UV Transilluminator is a compact, portable device used to visualize nucleic acids, proteins, and stained gels under ultraviolet light, ideal for quick inspections in labs and fieldwork.
Key Features
- Compact and Portable Design
- Lightweight and easy to carry for field or lab use.
- Typically sized around 11 × 4 × 3 inches.
- UV Wavelength Options
- Available in single or dual wavelengths: 254 nm, 302–312 nm, and 365 nm.
- Dual wavelength models (e.g., 254 + 365 nm) allow flexibility for different staining protocols.
- Illumination Types
- Equipped with high-intensity UV tubes, white LEDs, or blue 470 nm LEDs.
- Some models include quartz filters for pure UV output, eliminating visible and infrared light.
- Power Options
- Operates on standard 110V AC or includes inbuilt battery for cordless use.
- Electronic high-frequency ballast ensures instant start and no humming.
- Low Heat Emission
- Designed to minimize heat generation, making it safe for prolonged use near sensitive samples.
Applications:
- Gel Documentation
- Visualize DNA/RNA bands stained with ethidium bromide or SYBR Green.
- Suitable for quick checks during electrophoresis workflows.
- Protein Analysis
- White light transillumination supports protein gel observation.
- Fluorescence Studies
- Blue light transillumination enables viewing of gels stained for blue light excitation.
- Field Diagnostics
- Handy for on-site molecular biology or forensic investigations.
- Educational Use
- Ideal for teaching labs due to its simplicity and mobility.
Safety and Usage Tips
- Always wear UV-protective goggles when operating.
- Avoid direct skin or eye exposure to UV light.
- Use in a well-ventilated area if working with volatile stains.
