Choosing the Right Pipette Tip

เขียนโดย mablesdw
Choosing the correct pipette tip can make all the difference in accuracy and precision. Choose the wrong tip and you risk contamination, wasting valuable samples and reagents, and even repetitive stress injury. Luckily, there are several different types of pipette tips. Here are a few tips to help you choose the correct tip for the job. And, remember: not all tips will fit your pipette, so if you're not sure which type to choose, check the guide provided by the manufacturer of the tips.
Choose a high-quality tip that meets the highest standards of purity. Filter pipettes can greatly impact the results of your pipetting experiments. That's why pipette tips should meet stringent purity standards. Choose a high-quality tip that's compatible with most pipettes. Make sure to check the tips' sizes and length before buying. Some tips can have large pore diameters, so they won't restrict your sample volume. Likewise, a low-volume pipette can use standard tips, while a small-bore model can handle high-volume samples.
Standard pipette tips are useful for a wide variety of applications, but don't have the lowest retention. That can cause cross-contamination. Filter tips, on the other hand, eliminate this risk by preventing the formation of aerosols, which are harmful particles that remain in the air for extended periods of time. You might wonder why these types of pipette tips are more expensive. There are many reasons, including convenience, but they're not the only ones.
The best tip for your experiment Right Pipette Tip  is one that has a high-quality filter barrier. By using a filter pipette tip, you can avoid cross-contamination of your samples and achieve more reliable results. When you're new to the lab, filter tips are useful training wheels. If someone accidentally aspirates a sample, it's easier to simply replace the tip than send the pipette to a lab to get fixed.
The most common reasons for using a  filter pipette tips   filtered pipette tip are cleanliness and reliability. Using one of these tips is safer than risking contamination with another specimen. This will ensure that your samples are completely protected from contamination. When new members of a lab use the pipette, the tip may be contaminated with the liquid being aspirated. It's better to just throw away the contaminated tip than to risk the expense of repairing the pipette piston.
The quality of filter pipette tips is determined by the type of polypropylene blend that makes them. High quality tips are made of virgin polypropylene without plastic additives. It is particularly important to look for polypropylene blends that don't have metal additives. Even if the pipettes come in various colors, check whether there are any additives to metals, such as lead or nickel.
For applications involving volatile, corrosive, or viscous chemicals, it's important to use filtered pipette tips. They prevent aerosols from being drawn into the tip cone and may damage the pipette barrel. And, of course, they're a bit more expensive. However, the cost savings are worth it when you consider how much you'll save by replacing tips instead of pipettes.
