| 摘要 |
A laboratory consumable having a polymeric coating, formed by exposing said consumable to pulsed plasma comprising a compound of formula (I), wherein the variables are as defined in the specification, for a sufficient period of time to allow a polymeric layer to form on the surface of the laboratory consumable; wherein the laboratory consumable is selected from pipette tips, filtration membranes, microplates immunoassay products, centrifuge tubes, microtubes, specimen tubes, test tubes, blood collection tubes, flat based tubes, aseptically produced containers, burettes, curvettes, needles, hypodermic syringes, sample vials/bottles, screw cap containers, or weighing bottles. Particularly preferred compound of formula (I) is 1H, 1H, 2H, 2H-heptadecafluorodecyl acrylate. Laboratory consumable of this type show significantly reduced liquid sample retention, maximum sample recovery and ultra non-binding properties, as well as oil and water-repellency.
