  • Patent number: 12623813
    Abstract: A method for providing a passivation layer or pH protective coating on a substrate surface by PECVD is provided, the method comprising generating a plasma from a gaseous reactant comprising polymerizing gases. The lubricity, passivation, pH protective, hydrophobicity, and/or barrier properties of the passivation layer or pH protective coating are set by setting the ratio of the O2 to the organosilicon precursor in the precursor feed, and/or by setting the electric power used for generating the plasma. In particular, a passivation layer or pH protective coating made by the method is provided. Pharmaceutical packages coated by the method and the use of such packages protecting composition contained in the vessel against mechanical and/or chemical effects of the surface of the package without a passivation layer or pH protective coating material are also provided.

  • Publication number: 20260014058
    Abstract: The present disclosure relates to methods and systems for coating pharmaceutical vessels. e.g. with a coating set that includes an oxygen barrier layer, that reduce the amount of particles present on the coated vessels. The present disclosure also relates to methods and systems for removing particles from vessels, e.g. after a coating is applied to an inner surface of the vessel. The present disclosure also relates to methods and systems for inspecting pharmaceutical vessels for particles prior to filling using machine-based visual analysis. Each of the above may be controlled and performed by one or more processors, thereby enabling a fully automated coating, cleaning, and/or inspecting operation for pharmaceutical vessels.

  • Publication number: 20250332351
    Abstract: A primary drug container is described having an injection-molded thermoplastic wall having an internal surface defining a lumen, a PECVD (plasma-enhanced chemical vapor deposition) drug-contact coating, and a polypeptide composition contained in the lumen. The drug-contact coating is on or adjacent to the internal surface, positioned to contact a fluid in the lumen, and consists essentially of SiOxCyHz. The primary drug container contains between a lower limit of 1,000 and an upper limit of 100,000 particles having effective spherical diameters greater than 2 and no more than 10 micrometers (?m) per mL of solution.

  • Publication number: 20250312537
    Abstract: A process for producing improved gaskets for use in matched syringe and plunger systems, preferably pre-filled plastic syringe systems. In particular, a process for making and inspecting non-continuous channels in or through a gasket film by laser treatment. The gaskets are useful in matched syringe and plunger systems providing high and consistent container closure integrity (CCI), and consistent break loose and glide forces over time, and sealability.

  • Publication number: 20250242092
    Abstract: A vessel including a thermoplastic wall enclosing a lumen is disclosed. The wall supports an SiOx composite barrier coating or layer, for which x is from 1.8 to 2.4, between the wall and the lumen. High Resolution X-ray Photoelectron Spectroscopy (XPS) shows the presence of an interface between the composite barrier coating or layer and the wall or substrate. In one aspect, the interface has at least 1 mol. % O3—Si—C covalent bonding, as a proportion of the O3—Si—C covalent bonding plus SiO4 bonding. In another aspect, the interface has an Si 2p chemical shift to lower binding energy (eV), compared to the binding energy of SiO4 bonding. The result is a tightly adherent composite barrier coating or layer having a high degree of adhesion to the substrate under practical use conditions. Methods of applying the composite barrier coating or layer are also disclosed.

  • Publication number: 20240375106
    Abstract: Blood sample collection tubes are described including a tube surface and a coating set comprising a tie coating or layer N of SiOxCy or SiNyCy applied to the tube surface, a barrier coating or layer of SiOx, and a pH protective layer of SiOxCy or SiNyCy. The C tubes optionally contain a fluid with a pH of 4 to 8, alternatively 5 to 9. The barrier coating or layer prevents oxygen from penetrating into the thermoplastic tube, and the tie coating or layer and pH protective coating or layer together protect the barrier layer from the contents of the tube. Processes of collecting high volumes of blood into the tube, and methods of isolating the various types of nucleic N acids from the collected blood sample are described.

  • Publication number: 20240269039
    Abstract: The present disclosure is directed to pharmaceutical packages, such as syringes, vials, etc., containing wave-shifting crystals that, when excited, emit light having one or more characteristics by which information about the package, such as a unique package identifier, may be obtained. The wave-shifting crystals may be rare earth doped crystals. In some embodiments, the wave-shifting crystals may be incorporated into or onto a wall of a vessel, e.g. a syringe barrel or vial, in a way that maintains transparency of the vessel wall. In other embodiments, the wave-shifting crystals may be incorporated into or onto a portion of the package that need not be transparent, such as a needle shield, tip cap, or vial closure. The wave-shifting crystals may be used to track and/or authenticate a pharmaceutical package.

    Abstract: Disclosed are plunger assemblies including various convertible plungers and methods of making the same. Each plunger assembly is configured for disposition within a barrel of a medical container, e.g., a syringe, and displaced within the barrel from an engagement position to a release position. The engagement position is configured to provide a compression seal between a storage sealing section of the plunger and an inner wall of the syringe barrel. In the release position, the compression seal is reduced or eliminated. Also disclosed are methods for making convertible plungers and assembling them into syringes, e.g., pre-filled syringes.
