In the precision operation of the laboratory, every detail is crucial, and the sealing of the centrifuge tube is undoubtedly one of the important links that cannot be ignored. For 1.8ml transparent plastic centrifuge tubes that are frequently used in biological sample processing, chemical analysis and other fields, their sealing performance is directly related to the accuracy of experimental results and the safety of samples.

Sealing is the key feature of the centrifuge tube to keep the internal sample stable and prevent leakage during high-speed rotation. For 1.8ml transparent plastic centrifuge tubes, this point was fully considered at the beginning of its design. Through the precise tube cover structure and material selection, it strives to achieve the best sealing effect during the centrifugation process. Good sealing can not only prevent the loss of samples due to leakage, but also effectively avoid cross-contamination between samples, ensuring the accuracy of experimental results.

Before using 1.8ml transparent plastic centrifuge tubes for experiments, it is an essential preparation to conduct a sealing check. Although this step is simple, it is crucial to ensure the success of the experiment. The inspection method is as follows:
Gently tighten the tube cap: First, take out the centrifuge tube to be used and gently tighten the tube cap to the appropriate position. Be careful not to use excessive force to avoid damaging the tube cap or tube body.
Observe for leaks: After tightening the tube cap, place the centrifuge tube on a stable table and let it stand for a while to observe whether there is liquid seepage or gas leakage. If there are obvious signs of moisture or gas escaping around the tube cap, it means that the seal is not good.
Take timely measures: Once a poor seal is found, appropriate measures should be taken immediately. If conditions permit, a new centrifuge tube can be replaced; if there is no spare centrifuge tube on hand, you can try to adjust the position and tightness of the tube cap and check again.

In addition to the sealing check before the experiment, the sealing of the centrifuge tube should also be closely monitored during the centrifugation process. Since the huge centrifugal force generated during the centrifugation process may have a certain impact on the sealing performance of the centrifuge tube, it is recommended to check the sealing of the centrifuge tube again in the early stage after the start of the centrifugation and before the end. If the centrifuge tube is found to leak during the centrifugation process, the centrifugation operation should be stopped immediately and appropriate remedial measures should be taken.

Sealing is one of the important indicators that must be paid attention to during the use of 1.8ml transparent plastic centrifuge tubes. Through effective sealing inspection and monitoring, we can ensure that the centrifuge tube can fit tightly to the tube body during the centrifugation process to prevent sample leakage, thereby ensuring the smooth progress of the experiment and the accuracy of the results. Therefore, in the daily work of the laboratory, we should attach great importance to the sealing inspection of the centrifuge tube and include it in the necessary preparation steps before the experiment.
