Precautions and common misuses when using the Cap crimper

In the laboratory, using the Cap crimper is a very common operation, but if it is not used correctly, it may cause experimental failure or accidents. The following introduces the precautions and common misuses when using the Cap crimper.

1. Precautions when using the Cap crimper:

(1) Choose the right model. Choose the right Cap crimper according to the capacity and size of the sample container. Choosing a Cap crimper that matches the mouth of the sample container can ensure good sealing performance, avoid gas or liquid leakage, protect the sample from external contamination or oxidation, and facilitate uniform pressure transmission and improve the safety of the experiment.

(2) Check the condition. Carefully check the Cap crimper before each use to ensure that it is clean and has no deformation, cracks or other problems. Repair and replace it in time if any problems are found. Do not use it reluctantly. Forcible use may cause the internal sealing of the sample container to be insufficient. If the sealing is not good, it will cause the sample to interact with the external environment, resulting in data deviation.

(3) Be careful when placing the sample. Place the sample gently to avoid impact and tilting. Make sure the sample is located in the center of the Cap crimper to obtain uniform pressure distribution. If the sample is not centered, it will cause uneven pressure and affect the experimental results.

(4) Apply pressure slowly. Increase the pressure gradually and observe the working status of the Cap crimper to avoid sudden excessive pressure that may damage the sample or instrument. Excessive pressure may cause the sample to deform or rupture.

(5) Release the pressure promptly after the experiment. After the experiment, be sure to release the pressure completely and promptly to avoid damage to the sample under high pressure for a long time. If the pressure acts for a long time, it may have an adverse effect on the properties of the sample.

(6) Regular maintenance. Clean and check the Cap crimper regularly and deal with any problems in a timely manner. Keeping the Cap crimper in good condition is important for the quality of experimental data. Lubricating oil can be added appropriately to extend the service life.

(5) Pay attention to safety protection. Be sure to wear protective equipment such as gloves and goggles when using it to prevent accidents. Improper use of the Cap crimper may cause sample splashing or the Cap crimper to burst. Be careful.

2. Common mistakes when using the Cap crimper:

(1) Error 1: Failure to properly check the applicability of the Cap crimper. Before you start using the Cap crimper, be sure to confirm that it is suitable for the type and size of container you have on hand. The wrong choice may result in a poor seal or container damage.

(2) Error 2: Failure to perform proper maintenance and cleaning. The Cap crimper may accumulate dust and chemical residues during use. Regular cleaning and maintenance will not only extend the life of the Cap crimper, but also prevent cross-contamination.

(3) Error 3: Excessive force. When operating the Cap crimper, excessive force may not only cause damage to the container, but may also cause damage to the Cap crimper itself. The correct approach is to use steady force to ensure that the cap is pressed evenly.

(4) Error 4: Ignoring safety measures. When using the Cap crimper, you should always wear appropriate personal protective equipment such as gloves and goggles to prevent accidental injuries.

(5) Error 5: Failure to perform a tightness check. After completing the capping operation, you should check the tightness of the container to ensure that there is no leakage. This step is crucial to ensure the accuracy of the experiment.
