The wetting of pipette tips when pipetting aqueous liquids containing detergents like SDS or Tween 80 plays a critical role in the life sciences. Based on photometric measurements, BRAND Ultra Low Retention tips were compared with low retention tips from various manufacturers. The results clearly show that the BRAND Ultra Low Retention tips exhibit up to 16 times less residues, although the pipetting steps were performed by a variety of different people with various levels of experience in pipetting.
