Dual LED Blue/White Light Transilluminator WD-9403XX

Short Description:

The Dual LED Blue/White Light Transilluminator is an advanced dual-light-source imaging system designed for versatility and safety in the laboratory.

Blue Light Mode: Engineered for the visualization of nucleic acid gels, protein gels, and membrane stains. It is primarily used for the observation and gel-cutting operations of nucleic acid (DNA/RNA) gel electrophoresis. Compatible with a wide range of safe stains—including SYBR™ Safe, SYBR™ Gold, SYBR™ Green I & II, SYPRO™ Ruby, SYPRO™ Orange, and Gelsignal™ Green—this system eliminates UV-induced sample damage and protects laboratory personnel from the hazards of toxic dyes like Ethidium Bromide (EB).

White Light Mode: Tailored for biological laboratories to observe nucleic acid and protein gels post-polyacrylamide gel electrophoresis (PAGE) with silver staining. It delivers high brightness and uniform illumination with ultra-low power consumption and zero heat generation, ensuring sharp bands and deformation-free visualization even during prolonged observation.

FAQ

Q1: What is the main advantage of using a Blue LED Transilluminator over a traditional UV Transilluminator?

A: There are two major advantages: Safety and Sample Integrity.
Safety: Blue light (around 470nm) is completely safe for human skin and eyes, eliminating the risks of UV radiation and the need for heavy protective face shields.

Sample Integrity: UV light can cause photo-nicking, DNA breakage, and mutations within seconds. Blue LED protects your nucleic acid fragments, leading to significantly higher cloning efficiency during downstream gel extraction.

Q2: What types of stains are compatible with this system?

A: This dual-source system covers almost all common laboratory stains:

Blue Light Mode: Perfect for eco-friendly/safe nucleic acid stains such as SYBR™ Safe, SYBR™ Gold, SYBR™ Green I & II, GelGreen, RedSafe, and Gelsignal™ Green, as well as protein stains like SYPRO™ Ruby and SYPRO™ Orange.

White Light Mode: Ideal for colorimetric protein stains (Coomassie Blue, Silver Staining) and western blot membranes. (Note: It is not recommended for traditional Ethidium Bromide (EB/EtBr) as EB requires UV light for optimal excitation).

Q3: Why does the system include a 10-level intensity adjustment feature?

A: Different stains and gel thicknesses require different illumination levels.

Lower levels prevent signal saturation and band bleaching during prolonged observation or manual gel cutting.

Higher levels are optimized for detecting weak, low-concentration bands or capturing publication-quality images using gel documentation cameras.

Q4: Can I perform gel cutting directly on the glass surface? What about eye protection?

A: Yes, you can. The system features a stepless adjustable filter shield (amber filter) that filters out the blue light glare, allowing you to see sharp, glowing bands clearly. The shield can be adjusted and fixed at any angle, permitting comfortable, single-handed gel-cutting operations without the need for protective goggles. For surface protection, we recommend using a gel cutting plate/shield to prevent scratching the glass.

Q5: What is the lifespan of the LEDs, and how does the device handle heat?

A: The device is engineered with high-power, industrial-grade LED beads that offer a lifespan of up to 50,000 hours (meaning no bulb replacements needed for years). It is built with an integrated metal base plate for advanced heat dissipation. This ensures the device remains cool to the touch and prevents your agarose or polyacrylamide gels from melting or deforming during long-duration observations.

Q6: Does the transilluminator suffer from screen flicker when taking photos with a smartphone or camera?

A: No. The device utilizes an optimized, uniform transillumination mode with an illumination uniformity of greater than 90%. It is entirely screen-flicker-free, ensuring that when you take photos with a smartphone, tablet, or gel doc camera, you get a clean, low-background image with no dark lines or strobing effects.

Q7: What does the "5-minute auto-shutoff" function do?

A: To extend the lifespan of the LEDs and conserve energy, the system includes a smart safety timer. If the device is left idle or turned on for 5 minutes without manual adjustment, it will automatically shut off. You can instantly turn it back on with a single press if you need more time.
