  • Patent number: 10328460
    Abstract: A method of applying a coating to a device which has one or more components housed in a housing. A liquid coating precursor is applied to at least part of the internal surface of the housing and/or at least part of the one or more components within the housing. Low pressure conditions are applied to the closed housing, sufficient to cause the liquid coating precursor to evaporate and initiation of the liquid coating precursor to thereby cause the coating to form on at least some of the internal surfaces of the device.

  • Patent number: 8163356
    Abstract: A laboratory consumable having a polymeric coating, coating formed by exposing said consumable to pulsed plasma for a sufficient period of time to allow a polymeric layer to form on the surface of the laboratory consumable, said plasma comprising a compound of formula (I) where R1, R2, R3 and R4 are as defined in the specification. Consumables of this type show significantly reduced liquid sample retention, maximum sample recovery and ultra non-binding properties, as well as oil and water-repellency.
