200ul Ultra Long or 300ul Low Retention Pipette Tips

Low Retention pipet tips are specifically designed for applications requiring high accuracy and reproducibility especially pipetting viscous liquides in complex reactions such as PCR, RT PCR, and DNA sequencing. Pipetting viscous liquids also creates pipetting problems due to the inability to expel fluid because of surface adhesion between the liquid and the inside of the pipet tip. This fluid retention can be quite a problem because of residual liquid typically remain in the pipette tip after the operation.
