Dear friend Yun Sawa

Let's clarify the difference between non-filter and aerosol barrier pipette tips.

Non-filter Pipette Tips:

Non-filter pipette tips refer to tips that do not have any filtration mechanism. These tips are typically used for general liquid handling applications where the risk of contamination is low. They are suitable for transferring non-hazardous liquids, routine laboratory work, or when working with samples that do not require sterile conditions.

Aerosol Barrier Pipette Tips:

Aerosol barrier pipette tips, on the other hand, are designed with an additional feature to prevent the aerosolization of liquid samples. These tips contain a filter barrier within the tip that acts as a barrier against aerosols, preventing the transfer of contaminants or sample carryover. The filter allows air to pass through while blocking liquid, providing an added layer of protection during pipetting.

Regarding the Fisher brand pipette tips you mentioned, it appears that the "SureOne Aerosol Barrier Pipette Tips" offer the aerosol barrier feature, as indicated in the product description on the Fisher Scientific website. The confusion may have arisen from the packaging box label stating "Comprehensive line of non-filter and aerosol barrier pipet tip," which seems to suggest that Fisher offers both non-filter and aerosol barrier tips as part of their product range.

To ensure complete clarity and accurate information, I recommend reaching out to Fisher Scientific directly or referring to their product documentation for detailed specifications and clarification on the specific features of the pipette tips you have purchased.
