How to Fix Leaky Pipet Tip Channels

You can fix a leaky pipet tip channel by replacing the tip or sealing the leak with silicone sealant. If the leak is small, you can also apply tape to seal the hole. Before you proceed, it’s important to test the pipet with a known volume of liquid.

A leaky pipet tip channel is an indication of a broken or damaged seal. The tip should be replaced if it is blocked or shows visible wear. Depending on how often you use the pipet, it may need to be replaced every week, every month, or every few months. There are several causes of leaky pipettes, including broken or damaged seals, corrosion of the stem, or shaft, and more. Sometimes, a simple cleaning of the internal parts of a pipet will resolve the problem.

Using an alcohol swab can be effective at cleaning a leaky pipet tip channel. To clean a pipet tip channel, hold the swab horizontally in the middle of the channel. Next, insert the alcohol swab into the channel and rotate it clockwise. Afterward, remove the swab from the pipet tip channel. A clean pipet tip channel prevents the tip from getting contaminated with liquid during use, and helps the pipet tip stay sterile.

A leaky pipet tip channel is an obvious safety issue because leaking liquid can contaminate the surrounding area. It can also damage equipment and other chemicals. It can also be a health hazard, which is why it is important to seal the tip channel before using it. To avoid this problem, you should purchase a high-quality pipet, one that has been made with care. It should not be more than five years old, and it should be checked for debris before each use.

A leaky pipet tip can also be a sign of corroded pistons or o-rings. In these cases, you may need to replace the tip. Alternatively, you can send it for service. In any case, a leaking pipet tip will ruin your lab work, so ensuring that the tip seal is intact is important.
