BRAND Ultra Low Retention tips feature a patented surface treatment to make the polypropylene of the pipette tips extremely liquid repellent thus reducing costly sample loss during pipetting.

  • Ultra-hydrophobic tips are ideal for biological samples that contain detergents such as Triton X-100, SDS, Tween etc.
  • Special patented process does not use coatings that might lead to sample contamination.
  • Highly homogeneous surface is free of defect sites, preventing non-specific binding.
  • High chemical resistance is ideal for working with solvents.
  • Autoclavable.

A Persistent Problem.

  • Limited volume samples, costly enzymes and reagents, and foaming liquids all need to be pipetted with high precision.
  • However, close inspection of conventional pipette tips reveal that fluid droplets or a thin film of liquid remains in the pipette tip after dispensing.
  • Significant factors leading to these residues are the different surface energy components and molecular composition of the pipette tips and the sample being pipetted.

A Slick Solution.

  • The new, ultra-hydrophobic BRAND pipette tips and filtered pipette tips solve the problem.
  • The surfaces of the Ultra Low Retention tips are produced through a special, patented physiochemical process.
  • The homogeneous, defect-free surface produced has extremely low surface tension.
  • This significantly reduces sample loss and provides substantially higher reproducibility when working with critical media.

The Dirty Secret of Detergents.

  • In biological applications, such as PCR, PAGE or many other areas of protein chemistry, the samplemust often be treated with detergent.
  • An exact appraisal of the behavior of polypropylene surfacesin these applications is complicated.
  • Detergents significantly decrease the surface tension ofliquids, which hinders the optimal dispensing of the liquid from the pipette tip and diminishes pipetteperformance.
