Pipette tips are usually made of clear plastic materials such as polypropylene or polyethylene. There are two types of pipette tips: disposable and reusable.
Disposable pipette tips are usually made of plastics such as polyethylene or polypropylene and are relatively inexpensive. It can be discarded directly after use, avoiding the process of cleaning and disinfection, which is convenient and quick. Furthermore, it is less likely to contaminate samples or reagents, reducing the risk of cross-contamination.
The reusable pipette tips are usually made of high-quality polycarbonate or silica gel, which are more durable and corrosion-resistant, so they can be used multiple times, reducing costs and being environmentally friendly. In addition, it can be cleaned and sterilized as needed for repeated use.
Which pipette tip to choose should be considered according to actual needs and budget. Disposable pipette tips are recommended if some experiments or operations that require strict avoidance of contamination are required. If you need to use the pipette frequently, you can choose reusable pipette tips, but you need to do a good job of cleaning and disinfection.
