-
UV light transilluminators: Ideal for visualizing nucleic acids stained with ethidium bromide or similar dyes. Ultraviolet wavelengths highlight fluorescent bands in gels, enabling precise visualization.
-
LED light transilluminators: More modern and energy-efficient. LED light is less harmful to samples and users, making it a safer option for continuous lab work.
-
Mixed transilluminators: Some models combine UV and LED light, providing greater flexibility in experiments. This type of transilluminator is perfect for labs needing to work with various staining methods and samples.
Each model has its own advantages, and the right choice will depend on the types of samples you work with and your specific needs.
Why Does the Transilluminator Have This Price?
The cost of a high-resolution Kalstein transilluminator can vary depending on the model and its features. When comparing prices, it’s important to consider factors such as the technology employed, the quality of materials, and customization options.
Investing in a quality transilluminator is justified for several reasons:
-
Advanced technology: The inclusion of LED lights, high-sensitivity filters, and adaptable surfaces requires a high level of technological development.
-
Durability: These devices are built to last, making them a long-term investment.
-
Energy efficiency: The low energy consumption of modern models is another factor influencing the price, as it reduces long-term operational costs.
In summary, while the price may seem high initially, a high-quality transilluminator represents long-term savings in terms of durability and efficiency.
Compare the Transilluminator with Similar Products
When comparing a Kalstein transilluminator with products from other brands, such as Bio-Rad or Thermo Fisher, notable differences in both price and technical features become apparent. Bio-Rad transilluminators are renowned for their robustness but can be more expensive and less energy-efficient compared to more modern Kalstein models.
On the other hand, Thermo Fisher transilluminators offer excellent image quality, but they tend to be less ergonomic and heavier. In contrast, Kalstein’s newer models offer greater portability, making them ideal for labs with limited space or researchers who need mobility.
These comparisons highlight how technological innovation in some Kalstein transilluminators can offer advantages in both efficiency and versatility without sacrificing quality.
