Pipette tips are disposable attachments placed on the end of the pipette. They are primarily used to transfer liquids precisely in a laboratory setting. They come in a variety of sizes and shapes. Since most pipette tips are single-use and disposable, they prevent cross-contamination. 

Their classification is based on design, sterility, and functionality. Let's examine the distinctive tips and their applications.

Standard Pipette Tips

It is most commonly used for general liquid transfer. These tips are made from durable polypropylene and come in various sizes, such as 10µL 200µL and 200L. They suit routine laboratory work and chemical and biological experiments. 

These tips stand out because of their wide availability and their cost-effective nature.

Filter (Barrier) Pipette Tips

These tips contain a hydrophobic filter that prevents contaminants or impurities from entering the pipette. They are primarily used in more complex and sensitive experiments where contamination can affect the results. Filter tips are commonly used for PCR, DNA, and RNA research.

These tips stand out because of how efficiently they can work with volatile or hazardous liquids.

Low-Retention Pipette Tips

The coating with the hydrophobic surface minimizes the liquid adhesion and ensures the sample transfer is done safely. These tips are usually used to transfer valuable or precious samples. They are best known for reducing the overall sample loss and are suited for proteins and other viscous liquids.

The nature of these tips elevates sample recovery and reproducibility, protecting against the loss of critical elements in the transfer procedure.

Extended-Length Pipette Tips

They are longer than the standard pipette tips and allow for a deeper sample aspiration. These tips make handling hazardous or sensitive samples easy since they avoid contamination from pipette barrel contact.

It is Ideal for microbiology and cell culture applications.

In conclusion, choosing the right type is essential for achieving the desired accuracy, preventing contamination, and optimizing laboratory workflow. If you are looking for pipette tips, a pipette tips supplier can assist you in the same.
