FAQ of Pipette Tips

What are filter tips?

Filter tips are used to prevent cross contamination or “carry over” from one sample to another. When samples are aspirated into a pipette tip, a fine mist or “aerosol” is created, which can get into the pipette. Even after changing the tip, the aerosol can contaminate the next sample.

Are filter tips sterile?

Tips you've autoclaved yourself are sterile, which means that they are free from living organisms, but not necessarily from RNase and DNase.

What size are filter tips?

As you'll have spotted there's lots of different sizes of filter tips. The standard is 8mm, which is what you'll see, incorporated in most packet pre-rolled cigarettes. However for rolling your own these can be a bit tricky so most people like to use a slimmer filter.
