UV repeatability is high, and functional operation is simple

In the field of modern biological science research, experimental efficiency and accuracy are crucial. VL ® As a versatile ultraviolet radiation system, the series of ultraviolet radiation instruments are like a shining star, bringing unprecedented convenience and efficiency to numerous biological experiments.

1、 Core Function - Fast and Efficient Crosslinking

In nucleic acid research, cross-linking DNA or RNA onto nylon or nitrocellulose membranes is a crucial step. VL ® The series of UV crosslinking devices perform better in this regard, with a crosslinking process that takes only 25-50 seconds. In contrast, traditional methods require placing the film in a vacuum oven and baking it at 80 ℃ for up to 2 hours. The use of ultraviolet radiation coupling not only greatly shortens the experimental time, but also surprisingly enhances the hybridization signal, providing strong guarantees for the accuracy and reliability of the experimental results.

2、 Widely applicable fields

Membrane cross-linking technology

VL ® The series of UV crosslinking instruments play an important role in various membrane crosslinking technologies, such as Northern, Southern blotting, and EMSA. These technologies are indispensable in nucleic acid detection and analysis, and the application of UV Vis can ensure the efficiency and accuracy of the experimental process.

Bimolecular crosslinking

In molecular biology research, bimolecular crosslinking experiments such as CLIP seq, iCLIP seq, PAR CLIP seq, pBpa, sulfo SDA, psoralen, etc. can all rely on VL ® The series of purple diplomatic instruments can be easily completed. It provides stable and reliable technical support for these cutting-edge studies, helping researchers explore molecular mysteries in depth.

Microbial inactivation

Whether it is microorganisms such as bacteria, fungi, or viruses, VL ® The series of purple diplomatic instruments can achieve effective inactivation. This function is particularly important in microbiology research and related biosafety protection fields.

Other diversified applications

From light stability verification to DNA cutting in agar gel, from RecA mutation screening to partial restriction enzyme digestion produced by thymic dimer, to UV sterilization to eliminate PCR pollution, as well as UV sterilization and polymer solidification (such as hydrogel, methyl methacrylate resin), VL ® The series of purple diplomatic instruments have demonstrated powerful application capabilities and can be regarded as versatile assistants in biological experiments.

3、 Accurate energy control and diverse modes

To ensure excellent performance with each cross-linking, each VL ® The series of ultraviolet radiation detectors are equipped with excellent ultraviolet radiation illuminance meters (UV energy meters). This device can accurately measure ultraviolet energy and effectively compensate for the power output aging problem of ultraviolet lamps over time of use. The equipment is strictly calibrated according to national standards before leaving the factory, ensuring the accuracy and consistency of radiation energy regardless of changes in the strength of the ultraviolet light source or the length of use.

In addition, the instrument also provides multiple operating modes for users to freely choose from, including Auto Mode, which can intelligently operate according to sample requirements; Energy Mode, which can precisely control energy input; Time Mode, convenient for users to perform cross-linking operations according to specific times; Preset Mode, meeting personalized needs in different experimental scenarios.

4、 Rich selection of light sources with excellent performance

VL ® The series of ultraviolet radiation detectors provide users with multiple light source options, covering 254nm (UVC), 302nm (UVB), and 365nm (UVA). Different wavelengths of light sources are suitable for different experimental needs, and users can flexibly choose according to actual situations, further enhancing the universality and practicality of the instrument.

5、 Security and Humanized Design

Safety interlock device

In terms of safety, VL ® The series of purple diplomatic liaison instruments can be described as well intentioned. The instrument is equipped with a safety interlock device, which automatically shuts off the ultraviolet light source when the door is opened or not tightly closed. This design fully considers the safety of users and avoids UV radiation injuries caused by misoperation.

Lamp replacement prompt function

The instrument also has a thoughtful lamp replacement prompt function. When the power of the lamp tube drops below 60% of the initial value, the prompt light will turn on to remind the user to replace the lamp tube in a timely manner, ensuring that the instrument always maintains good working condition.

Friendly and safe observation window

The observation window adopts a 5-layer special glass design, which ensures that users can safely observe the operation status of the sample and lamp through the window without affecting the normal operation of the experiment, reflecting the humanization of the instrument design.

Good consistency of light source distribution

From the energy distribution map, average value, and standard deviation of the ultraviolet radiation analyzer (see attached table), it can be seen that the light source distribution of the instrument, especially in the central area, has very good consistency. This means that during the experimental process, each point of the sample can absorb essentially the same amount of energy, thereby ensuring the stability and reliability of the experimental results.

VL ® With its fast and efficient cross-linking function, wide range of application fields, precise energy control, rich selection of light sources, and perfect safety guarantee and humanized design, the series of purple diplomatic linkage instruments are undoubtedly the ideal choice in the field of biological science research. It will help researchers make great strides in exploring the mysteries of life.
