Manual Syringe Stopper Press

Effortless manual syringe stoppering for small-batch aseptic production, delivering precise air removal, pharmaceutical-grade construction and a compact benchtop design.

Product details

  • Manual Stoppering for Pre-Filled Syringes
    The Manual Syringe Stopper Press is designed for controlled stoppering of pre-filled syringes in laboratory and small-batch pharmaceutical environments. Its lever-operated mechanism provides consistent, repeatable stopper insertion while maintaining operator control.
  • Wide Syringe Compatibility
    Suitable for glass flanged syringes, glass cartridges and plastic flanged syringes. Interchangeable change parts allow processing of syringe bores from 6.35 mm and above, supporting a wide range of dosing formats.

  • Standard Syringe Formats Supported
    Short lead-time change parts are available for the small Syringe Stopper Press to suit:

    • Flanged glass syringe 6.35 mm bore
    • Flanged glass syringe 8.6 mm bore
    • Flanged glass syringe 11.8 mm bore
    • 3 ml glass cartridge, 9.7 mm bore

    Additional syringe formats can be accommodated subject to assessment of samples. For larger formats, a large Syringe Stopper Press variant is available to process syringes with bores from 14 mm to 28 mm (up to 50 ml).

  • Controlled Air Removal for Fill Integrity
    The lever-controlled pressing system seats stoppers to a precise position while allowing trapped air to escape past a polished air-bleed strip. Interchangeable bleed strips of different lengths are available to suit varying liquid fill depths, ensuring consistent air removal and stopper placement.
  • Pharmaceutical-Grade Contact Materials
    All product contact parts are manufactured from 316L stainless steel, with material certification provided. This supports hygienic operation and use in regulated pharmaceutical and aseptic environments.
  • Adjustable, Repeatable Stopper Positioning
    Fine adjustable stops allow precise control of stopper depth within the syringe. Adjustments can be made using a single tool, ensuring repeatability across production runs.
  • Simple Manual Lever Operation
    The intuitive lever action provides controlled stopper insertion with minimal training required, making the system ideal for laboratories, pilot plants and short-run production.
  • Compact Benchtop System
    The small footprint design fits easily into restricted workspaces while maintaining stable, ergonomic operation.
