ULR Pipette Tipssterile and non-sterileLiquid HandlingUltra Low Retention Pipette TipsThe surfaces of the Ultra Low Retentiontips are produced through a special, patentedphysicochemical process. The homogeneous,defect-free surface thus producedhas extremely low surface tension – over50% less than PTFE (see table). This significantlyreduces sample loss and providessubstantially higher reproducibility whenworking with critical media. Ideal for biological samples that containdetergents 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 workingwith solvents. The tips can be autoclaved at 121 °C(2 bar) without damaging the materialproperties.Standard pipette tipUltra Low Retention pipette tipSurfaceBRAND ® PP Ultra Low RetentionPTFESiliconeUntreated PPWaterSurface tension9 mN/m19 mN/m21.5 mN/m30 mN/m72 mN/m0.1 - 20 µlULR pipette tips, 0.1 - 20 µlQuantity Pack of non-sterileCat.
