The gel transilluminator is a fundamental tool for the visualization of DNA and RNA fragments in gel after electrophoresis. This device, of great importance in laboratory research, needs special and methodical care to ensure its proper functioning and to extend its lifetime. In this article, we will share some essential guidelines on how to carry out proper maintenance of the transilluminator.
Before performing any maintenance, it is crucial to understand how this device works. The gel transilluminator uses ultraviolet light to make DNA or RNA fragments visible in the gel. This light comes from high-pressure mercury junctions that reside inside the device. Fluorescent substances present in the gel absorb this light and emit it at a different wavelength, allowing visualization of the DNA fragments. Improper handling of this sensitive machinery can cause irrevocable damage, so it is vital to be informed about its proper operation and maintenance.
Preventive Maintenance of the Ultraviolet Light Apparatus
Performing preventive maintenance on the transilluminator can prevent unexpected damage and avoid costly replacements. Here are three basic steps to follow:
– Regular Cleaning: You should make sure the transilluminator is clean before and after each use. Any dirt or debris can interfere with its operation. It is recommended to remove any residue with an electrical contact cleaner.
– Checking the UV light unit: With regular use, the mercury junctions may deteriorate, losing their efficiency. Visually inspect the UV light unit regularly to detect possible failures early.
– Scheduled maintenance: It is good practice to schedule routine maintenance checks. This will allow constant monitoring of its performance and early detection of potential problems.
Corrective Maintenance Actions for the Transilluminator
If, despite regular maintenance, the transilluminator appears to have problems, some of these steps may be helpful in correcting them:
– Replacing the mercury junctions: If any failure or damage to these junctions is identified, they should be replaced immediately to prevent further damage.
– Check the wiring: Sometimes problems with the transilluminator can be due to faulty connections. Check the wiring and replace or repair as necessary.
– Consult the supplier: If problems persist, contact the equipment supplier. They can provide expert assistance and solutions specific to your transilluminator model.
