What is a pipette tip? It is a small, cheap and indispensable part of a scientific apparatus. It powers the research that goes into developing new drugs, such as Covid-19 diagnostics, and every blood test that is performed. A bench scientist may use dozens of these tips a day. Yet, the supply chain of pipette tips is severely hampered by pandemics and blackouts.
A pipette tip is an important tool in scientific experiments, such as those used in Covid-19 tests. Unfortunately, natural disasters and freak accidents can disrupt this supply chain. A recent statewide blackout in Texas killed more than 100 people, and several pipette manufacturing facilities were forced to close. These incidents have made it difficult for researchers to continue their work, especially since polypropylene is the main raw material for pipette tips.
While pipette tips are relatively simple in design, they must be accurate and precise. As with most other laboratory equipment, there are many factors to consider when choosing the right one. The first is the material that the tip is made of. It must be made of virgin polypropylene, which is free of plastic and metal additives. This type of polypropylene ensures that the tips are safe for samples and for sensitive applications.
The next factor to consider is the color. The color should not contain metals or dyes, as these can lead to contamination. For colored tips, you need to look for tips that do not contain metal or plastic additives. In addition, plastic-based tips do not have metal fibers, but polypropylene tips are not recommended for biological work.
Another important characteristic to look for in a pipette tip is the polypropylene blend. A quality tip is made of virgin polypropylene without any additives, including metal. A pre-sterilized pipette tip is safer to use in biological studies because it is free of DNA, RNase, ATP, and pyrogens. This feature is especially important if the pipette is used to analyze samples.
A high-quality tip is made from virgin polypropylene and has no plastic or metal additives. Only virgin polypropylene tips are safe for samples, while non-virgin polypropylene tips are not. As such, you should only buy virgin polypropylene tips if you can afford them. If you don't have a lot of money, you can opt for a cheaper alternative.
Also, filtered tips can be used for sensitive experiments. It is also important to choose a polypropylene filtration device.
The design of a pipette tip is important. It is important to choose the right one based on the conditions of its use. Different types of chemicals may require different types of tips. A non-sterile pipette tip, for example, will not be suitable for chemically-based liquids. A sterile tip should be resistant to the presence of a variety of solvents.
So, when choosing a pipette tip, it is essential to look for its polypropylene blend. The pipette tip is the basic part of a pipette. It is used to apply suction to liquids. Chemists used the pipette tip much like a straw. They put their mouth on the open upper end of the pipette and used their lung power to suck up the solution. While it is not necessary to use sterile pipes, it is important to be seated properly to avoid any discomfort or injury.
