Ultra Low Retention-Pipette tips and Filter tips (ULR)The surfaces of the Ultra Low Retention tips are produced through a special, patented physicochemical process. The homogeneous, defect-free surface thus produced has extremely low surface tension - over 50% less than PTFE (see table). This significantly reduces sample loss and provides substantially higher reproducibility when working with critical media.

• Ideal for biological samples that contain detergents such as Triton^™ X-100, SDS, Tween etc
• No additives that can be leached out! No siliconization of the surface!
• High chemical resistance. Ideal for working with solvents
• The tips can be autoclaved at 121°C (2 bar) without damaging the material properties
