Thermal cyclers, also known as DNA amplifiers, PCR machines, or thermocyclers, actively amplify segments of DNA in laboratory settings using the Polymerase Chain Reaction (PCR) technique. These versatile apparatuses consist of a thermal block with holes for inserting tubes, enabling the occurrence of PCR mixture reactions. The cycle actively lowers or raises the temperature of the block in pre-programmed, discrete steps. Laboratories involved in molecular biology and gene cloning rely on thermal cyclers as important equipment. They offer a range of models and sizes, allowing the selection of larger or more compact versions based on available lab space.
In the world of laboratories, particularly in the field of molecular biology, thermal cyclers take center stage as the primary equipment. Referred to by various names such as PCR machines or thermocyclers, they play a crucial role in facilitating DNA growth. These tireless machines actively amplify DNA, effectively producing more genetic material. If you're looking to purchase thermal cyclers for your lab, our website offers convenient online options. While many thermal cyclers are available, selecting the right one becomes easy when the lab identifies its specific requirements and chooses the appropriate type. Benchmark Scientific's thermal cyclers find applications in a variety of settings. In research labs, they serve as DNA wizards, actively assisting scientists with their experiments. They are also utilized in clinical environments by doctors who employ them for genetic tests to diagnose specific diseases. These machines possess a remarkable ability to unlock the hidden secrets encoded within our genes.
To prevent failures and malfunctions, prioritizing the care and maintenance of thermal cyclers is essential. Regular daily maintenance and post-protocol execution maintenance, in addition to basic care practices, actively minimize issues associated with these instruments.
Regular maintenance plays a vital role in ensuring optimal functioning. Ensuring regular attention and proper care for these devices is crucial due to the potential impact of failures on the accuracy of scientific research. In the laboratory, where precision is of utmost importance, the regularity and consistency of equipment maintenance can make the difference between a successful experiment and a costly setback.
Furthermore, aside from maintaining accuracy, regular maintenance serves as a preventive measure against more severe issues that could necessitate the purchase of new equipment. This approach also proves cost-effective in the long term, as it extends the lifespan of the thermal cycler and minimizes the need for additional expenses.
To maintain contamination-free results and extend the lifespan of your PCR machine, it is essential to keep it clean. However, cleaning can be challenging as introducing liquids into the thermocycler could cause damage. Follow this straightforward and safe cleaning routine:
1. Begin by turning off and unplugging the machine. Allow it to cool down for 20-30 minutes. This ensures that critical areas such as the lid, wells, and sample block reach room temperature and eliminate any remaining electrical charges.
2. Use a soft cleaning cloth to gently wipe the exterior of the machine. Microfiber cloths designed for computer screens work effectively. For stubborn stains or sticky residues, you can lightly moisten a soft cloth with a soap solution of neutral pH. Take extra care to prevent any water from entering the unit.
3. Clean the sample block, which is particularly susceptible to contamination. Use a lint-free cloth or swab soaked in isopropanol, a mild detergent, or a DNA/RNA decontamination solution recommended by the manufacturer. Thoroughly clean the wells and edges, ensuring they are completely dry before finishing. If there is residual moisture, use a dry swab. Similarly, clean the bottom of the hot lid with a cloth or swab soaked in isopropanol, as mentioned earlier. Once again, wait for everything to dry before returning it to its normal position.
4. Lastly, gently clean the vents using a small brush or by passing a cloth moistened with isopropanol over them.
Remember to follow these steps meticulously to maintain a clean and well-functioning PCR machine.
Once a year, conduct a comprehensive examination of your machine. Inspect the electrical supply and wires to ensure they are in good condition. Next, carefully assess the control buttons or display for any signs of damage or unresponsiveness. Lastly, follow the detailed cleaning procedure mentioned earlier to ensure a thorough cleaning.
