Why are pipette tips important ?
What are pipette tips ?
Pipette tips are used with pipettes and pipettors to speed processing and reduce cross-contamination. They are available in a variety of materials and styles.
How many kinds of pipette tips are there?
Popular pipette styles used are: Universal pipette tips, Filter pipette tips and Low retention pipette tips.
Disposable pipette tips are very important for molecular biology, chemistry and medicine. These tips create an accurate pipetting system. There are several different types of pipette tips, the most common type of pipette tip being non-sterile. They are typically used in laboratory applications where sterility is not critical to the experiment or test being performed. Filtered tips Filtered pipette tips are designed to prevent aerosol formation. Aerosols are airborne small liquid or solid particles. These particles can actually stay in the air for a long time and can be inhaled. Filtered pipette tips help reduce the risk of aerosol formation in the laboratory. They also protect pipette stems from contamination and reduce the risk of cross-contamination. These pipette tips are often used in contamination-sensitive applications such as forensics and clinical diagnostics. Due to the potential for aerosol infection, we cannot stress enough the importance of enforcing safe work practices in the laboratory. This includes proper sterilization of pipettes and handling of pipette tips after use.
How to choose the pipette tips?
Quality really matters when choosing a pipette tip. No matter how good your pipette is, without the right pipette tips, you won't get the results you want. Here are a few suggestions to consider when choosing a tip:
Materials - A good pipette tip will be made of high quality virgin polypropylene. Beware of plastic and/or metal additives commonly found in blue and yellow tips, as these can contaminate the sample. If you choose filter tips, make sure the filter is made of polyethylene and does not contain additives such as cellulose.
Contamination Free - Make sure you only buy tips that are certified free of RNase, DNase, DNA, pyrogens, PCR inhibitors and ATP. This is even more important if you are performing sensitive microbiological testing.
Fit/Compatibility - Not all pipette tips will fit your pipette. It is important to ensure that the tips you are considering are suitable for your pipette. You don't have to force the tip onto the pipette, it should grab and hold in place with little or no force. Most pipette tip brands have a compatibility chart to help you choose the right tip. However, most tips should be compatible with almost every popular pipette brand in the world.
Low Retention - Low retention techniques have become more popular in recent years. They are generally considered premium tips and you can expect to pay more for them.
