There are many different standard/universal pipette tips on the market that can be used and interchanged across different manufacturer’s pipettes. However, lower price and universal fit is not always the best logic when selecting tips for your pipettes.
Manufacturer-Made Tip Used With That Manufacturer’s Pipette
This pair provides the best results. The tips are specifically designed to load, seal, and deliver the desired volume of liquid accurately and precisely.
Universal Tips Used With A Different Manufacturer’s Pipettes
If mixing manufacturers, users can expect up to a 10% margin of error in the volume of liquid aspirated/dispensed. This is due to various factors, such as:
- Tip sealing
- Pore size of filtered tips
- Tip thickness
- Tip opening
- Flash
- Tip autoclaving
Note: If filtered pipette tips are used, the pore size (micron size of the holes in the filter that allow air to pass/permeate through) can affect the volume of liquid dispensed due to different pore sizes and materials used by different tip manufacturers). Air flow can begin to be restricted when the pore size is smaller than ~20uM (microns).
