When purchasing pipette tips, the first thing to consider is the type of polypropylene the tip is made from. Virgin polypropylene is free from plastic and metal additives and therefore, is a safe material to use for your samples. Ensure that the tip you purchase contains no metal additives, particularly if the tip is colored. These additives may harm the sample and may also cause contamination.
If you have a newbie in your lab, the filter tips on pipettes can help you learn proper technique and avoid contamination. This can help prevent PCR contamination and sample carryover. A good set of filter tips can also act as training wheels for a newbie. When a new lab member accidentally aspirates a liquid, it's easier to discard the tip than to send the entire pipette to a technician.
If you're using a pipette for research purposes, the brand of tips you use is not the only important factor in choosing the right one. Other factors to consider when choosing the right tip include the quality of the injection molding machine. Even minor variations can significantly affect the results of a study. If you use cheap pipette tips, you run the risk of ruining your study. If you need to purchase a new pipette, make sure you purchase an affordable brand instead of a low-quality one.
The quality of the pipette tip is an important factor in accuracy. If you're using an old pipette, it's likely that the tip is not the same as the one that came with the machine. This is because the quality of the tips depends on the injection molding machine. However, these minor differences are hard to spot, but the results of the study will suffer if you choose a cheap pipette tip.
Pipette tips are an essential tool for a scientific laboratory. Regardless of the size of the pipete, tips are necessary for every procedure. While the tip's appearance is plain, it's crucial to choose one that meets your research needs. While there's no single tip that will work best for all applications, it's best to get the right fit. You'll be able to save time and money when you purchase a universal pipette.
The most important consideration when buying pipettes is the type of tip. The correct fit is essential when using a universal tip, and the same holds true for standard-size pipettes. It's better to use a universal tip for every application and avoid the hassle of comparing two different brands. The most important thing to remember is that the fit is not as important as the accuracy of the tip. The tips are not sterile.
There are many reasons to choose a brand-specific tip. Some manufacturers have a policy that allows users to try out different brands of pipettes without actually purchasing them. It's a good idea to buy a variety of sizes and types to reduce the risk of a product malfunction. Some companies have also incorporated ergonomics into their designs. In addition to ergonomics, a well-made tip is more comfortable for you.
Apart from quality, pipette tips are brand specific. The quality of a tip will depend on how well it fits the pipette and the manufacturer's equipment. A poorly-fitting tip will cause air to escape from the pipette barrel and will negatively impact the study. If you are buying a universal tip, it will be more suitable for your experiments. You should make sure to purchase the tip only if you are confident with its quality.
Moreover, pipette tips that are made from hydrophobic and low-retention materials are more likely to withstand chemicals and solvents. The quality of a pipette tip is important for the accuracy of the experiment. If you don't choose a high-quality one, you risk contaminating the sample. But a high-quality one is the best investment. And it's not just the quality of the material, it also helps to prevent bacterial contamination.
