When handling pipettes, it is important to inspect the tips before use. If the tip is bent or chipped, it may be old or even a stowaway pipette. You can identify these pipettes by checking their C-14 dating. Most breaks in pipettes are minor. They can include a chip at the tip edge or a small break in the wall of the pipette. These fractures interfere with the liquid's flow path.

When using volumetric pipettes, it is important to not blow out the tip. The pipettes are calibrated based on the volume of solution that remains at the tip due to surface tension. You can read your volumetric pipettes by holding the cap firmly on the mouth and letting the liquid drain out from the bottom. While you are delivering the liquid, the tip should still have a small amount of liquid in it.

One of the most common mistakes people make when using a volumetric pipette is not blowing out the tip. The nozzle is made to deliver a specific volume. When you are using a volumetric pipette, the tip is calibrated to take into account the amount of solution remaining at the bottom due to surface tension. So, instead of blowing out the tip, you should let the liquid drain out of the lower end.

When reading volumetric pipettes, you should not blow out the tip. It is calibrated to take into account the volume of liquid that remains in the tip due to surface tension. When reading the pipettes, be sure to place the cap firmly on the mouth. While this will prevent the liquid from escaping, it will ensure that the volume is correct. You should not squeeze or blow out a volumetric pipette to empty it.

The tip of pipette is not blown out. The last milliliter of the pipette is included in the tip. If you have a volumetric pipette, you should always check its capacity and blow out the tip. Depending on the size of the pipette, you can also check its accuracy. For example, if you are measuring the last milliliter of the sample, you should blow out the entire top of the pipette.

As the volumetric pipette is designed to deliver a single volume, it should never be blown out. Unless you need to perform a large amount of analysis, this instrument is not suitable for this purpose. It should be tightly sealed and the cap should be tightly secured. The fluid should be drained from the tip. Then, you should read the pipettes. However, do not squeeze them because this will cause spills.

When reading a volumetric pipette, look for the bottom half of the curve. When observing the tip, look for a small area of the curve where there is no liquid. If the tip is empty, it is time to make a new batch. If it is full, the solution is ready to use. Otherwise, use it as a standard for future measurements. For high precision work, you should not blow out the tip. For volumetric measurements, you should rely on other methods of measurement.

It is also important to know what type of pipette you're using. Volumetric pipettes have a ring on the upper neck. Unlike drinking straws, they are designed to be used by professionals. You should never attempt to use a volumetric pipette for analysis unless it is accompanied by a specialized reagent. Then, you should reverse the re-filling of the pipette.

In case you don't want to squeeze the pipette, you should keep the cap on tightly. A volumetric pipette has a ring on its mouth, which indicates it's volumetric. A TD pipette, on the other hand, isn't calibrated by the tip's diameter. The pipette's cap is usually shaped like a circle.
