  • Stopper Closure Processing

    Clean, sterile and dry closures, particularly rubber stoppers and plungers, are vital components of parenteral packaging. As closures are in product contact for considerable periods – and are a functional part of drug administration systems – it is absolutely essential that they are clean and sterile, with due consideration given to their physical, mechanical and chemical properties.

  • The Impact of Sterilization on Primary Packaging

    The following aspects of extractable studies are particularly important: 1. Extraction should take place using a plurality of solvents of different polarities and using several different types of extraction methods. ... To demonstrate this impact, his team has conducted a study with commercially available stoppers made of bromobutyl rubber for ...

  • Impact of extractables from rubber closures on

    The extraction of the rubber stoppers by use of 2-propanol led to the release of various compounds from the stoppers tested. The extraction resulted in rubber stopper specific extraction profiles (Fig. 1, chromatogram A, C-I).Chlorobutyl rubber stopper CB-1 particularly demonstrated a significantly higher content on extractable compounds (Fig. 1, chromatogram A).

  • Toxic effects of lab‐grade butyl rubber stoppers on ...

    Typically, incubation vessels are sealed with butyl rubber because these elastomers are essentially impermeable for gases. We report on the potential toxicity of five different commercially available, lab‐grade butyl stoppers on MOx activity in samples from marine and lacustrine environments.

  • Naturally Occurring Rubber Is What Color? –

    Why are rubber stoppers, rubber feet on electronics, and rubber tires all charcoal black? While natural rubber is great for things like water resistance, it isn’t particularly durable. In fact, its default flexibility is actually a hindrance in applications, like tires, where durability is more important than extreme flexibility.
