How Pipette Filter Tips Work?
Preventing Contamination
Blocking Aerosols and Liquid Splashes
Pipette tip filters play a critical role in preventing contamination during pipetting. These filters act as a physical barrier between the liquid sample and the pipette, reducing the risk of cross-contamination. Aerosol barrier pipette tips are particularly effective in blocking aerosols and liquid splashes.
- The filter inside the tip prevents aerosols from forming during aspiration and dispensing.
- It also stops viscous or volatile solutions from entering the pipette barrel.
- By creating a barrier, pipette tip filters protect both the sample and the pipette from aerosol contamination.
Using pipettes without these filters increases the risk of cross-contamination. Aerosols from the sample liquid can contaminate subsequent samples, leading to inaccurate results. Pipette tip filters ensure that biological contaminants do not compromise sensitive experiments.
Reducing Cross-Contamination
Cross-contamination poses a significant challenge in laboratory workflows. Pipette tip filters mitigate this risk by trapping residual liquid and aerosols.

Pipette Filter Tips vs. Standard Tips
Differences in Design and Functionality
Pipette filter tips and standard tips differ significantly in their design and intended use. Filter tips include a built-in hydrophobic barrier that prevents aerosols and liquid splashes from entering the pipette. This feature ensures contamination-free pipetting, especially in sensitive applications. In contrast, standard pipette tips lack this barrier, making them less effective at preventing contamination.
