In choosing pipette tips for a task, many factors must be considered. The application type and liquid properties are just a few factors that can guide the selection of pipette tips. There are various types of pipette tips available on the market. Some are sterile while others are non-sterile but can be later sterilized. Additionally, they offer options for length, low retention and wide apertures to correspond with different materials. With so many options to choose from, selecting the right one from a pipette tips supplier for a specific experiment, storage or solution can be daunting.
It is common to generate aerosols inside the pipette tip while aspirating liquids. This means that if you don't use a filter tip to fix the sample, the pipette will be contaminated. Not using filter tips or changing between tips can cause aerosol contamination as well as contaminating the next sample.
In most PCR applications, contamination can lead to false-positive results. This is because even the smallest amount of DNA from another sample may highlight during the detection process. Therefore, when conducting PCR applications or handling liquids that have potential damage, it's important to use laboratory pipette tips. Radioactive labels or corrosive samples may damage your pipette, leading to a shortened lifespan. Some liquids, such as RNA/DNA solutions and infectious samples, should always be pipetted using filter tips. Be cautious when handling acidic or alkaline, volatile or viscous samples to avoid cross-contamination and pipette damage.
Some tips are created with a long axis design for specific laboratory applications. They are designed with common laboratory errors that may cause cross-contamination in mind. Some technicians run the risk of contamination by inserting the rod of a pipette connected to a standard tip into a test tube trying to reach the bottom. This can be eliminated by using an elongated pipette tip. They are an ideal choice for laboratory instruments such as deep-well blocks and microcentrifuge tubes.
Never force cell samples through the narrow opening of a standard tip. These samples are very fragile and can easily be sheared. When handling fragile cell samples (including cell lines and violent materials), use a wide aperture pipette tip. It can prevent flow resistance and shearing of cell components when transferring samples through a wider opening.
