A technique for sealing glass syringes

P J Morris

    Anaesthesia
    |June 1, 1977
    PubMed
    Summary

    A novel device enables multiple sample removals from glass syringes without affecting oxygen levels. Storing the syringe in ice-water maintained sample integrity for up to one hour after aliquot withdrawal.

    Area of Science:

    • Biomedical Engineering
    • Analytical Chemistry

    Background:

    • Accurate sample collection and storage are critical for reliable laboratory analysis.
    • Maintaining sample integrity, particularly oxygen levels, is essential for certain diagnostic tests.

    Purpose of the Study:

    • To introduce and evaluate a new device for sealing glass syringes.
    • To assess the impact of multiple aliquot removals on sample oxygen content.

    Main Methods:

    • Development of a specialized sealing device for glass syringes.
    • Procedure involving multiple aliquot withdrawals from sealed syringes.
    • Storage of syringes in an ice-water mixture.
    • Measurement of oxygen content in samples post-aliquot removal.

    Main Results:

    • The described device effectively seals glass syringes, permitting multiple sample aliquot removals.
    • No significant deterioration in sample oxygen content was observed one hour after multiple aliquot removals.
    • Sample integrity was maintained when the syringe was stored in an ice-water mixture.

    Conclusions:

    • The developed syringe sealing device is suitable for applications requiring multiple sample aliquot removals.
    • The device ensures sample oxygen stability for at least one hour when stored appropriately, vital for oxygen-sensitive analyses.
