When choosing a pipette, make sure to choose one with sterile characteristics. This ensures that it is free of biological contaminants and that it will fit properly in the laboratory. It will save you money and time, and will ensure maximum accuracy. Read on for some tips for choosing the right pipette for your research. We've all been in a situation where you've had to bail out a colleague when their supply order doesn't arrive on time.
The first important characteristic to look for when selecting a pipette tip is the polypropylene blend. A high-quality tip will have no plastic or metal additives. This ensures that the tips are safe for samples. Filtered tips should also be filtered to prevent contamination of the sample. For color-coded tips, you should look for those that contain no metal additives. Dyes can contain additives such as nickel, which is dangerous for sensitive materials.
Non-sterile pipette tips are the most common type used in scientific work. While standard pipette tips are often sufficient, they are not suitable for every application. For example, if you need to use the same sample over again, you should consider buying a sterile pipette tip. A high-quality tip will ensure a good seal with the pipette.
Pipette tips are made from high-quality polypropylene. Some manufacturers market them as free DNA, pre-sterilized, and filtered for PCR. Others are marketed as cadmium-free. They're important for experiments that require highly-purified and sanitary pipettes. You'll find these types of tips at your local biotech or pharmaceutical store. And if you're looking for the perfect pipette for your research, make sure to choose a sterile one!
The first thing to consider when choosing a pipette is the polypropylene blend. Ideally, the polypropylene should be virgin polypropylene. This type of tip should not contain plastic or metal additives. This is particularly important if you're using colored pipette tips in biochemistry and chemical analysis. In addition, they should not contain any metals, as these can contaminate the samples and lead to reprocessing.
Besides polypropylene, the other types of pipette tips include filter tips and barrier tips. The first kind is a sterile tip and should be disposable. The other type is one with low-retention and will retain less liquid. These two types are the most common and can be used for different applications. It is important to use a pipete with the right tip to achieve the most accurate results.
The next type of pipette tip is a sterile pipette tip. It has a high retention rate and is ideal for using a variety of samples. It's important to check the polypropylene quality before buying any new tips. Ensure that they are sterile, as it can prevent cross-contamination and improve results. Alternatively, you might want to use a non-sterile tip if your experiments require sterility.
In addition to filter tips, pipette tips can also be microtips. These are used for smaller liquid volumes. Unlike standard tips, microtips have a low-volume sorbent bed, which reduces the volume that is dispensed. If you're using a standard tip, you may want to use a tip with a small sorbent bed. Those are the most popular types of microtips.
Apart from preventing cross-contamination, pipette tips are also essential for a laboratory experiment. They help scientists control fluid volumes accurately. They are often used for sensitive research. They are often expensive, but they are a good investment for labs. They're also easy to clean and can be used in clinical trials. If you need to perform a complex experiment, a sterile pipette tip is an essential part of a scientific kit.
There are several different sizes of pipette tips. A short tip is typically used for small wells and is suitable for 384 or 1,536-well plates. An extended-length tip is ideal for deep well blocks and is more ergonomic for the user. A long-tip will fit into a larger-sized well. This is the most popular type of tubete tip. It is the best for testing liquids in large volumes.
