Caps, Push Top, with thinned penetration point, inserted in smooth, polyethylene, Blue Caps. For use with 11mm Crimp or Snap Top, 12x32mm autosampler vials. MICROSOLV Brand. 100/PK.
Push caps are press‑fit vial closures designed for applications where convenience, speed, and short‑term sealing performance are required. This subcategory includes polyethylene push caps, colored push caps, shell‑vial caps, and 96‑well plate plugs used in chromatography and sample‑preparation workflows.
Push caps for shell vials are designed for quick installation and removal. These plastic caps rely on tight dimensional tolerances and friction fit to remain securely in place, making them suitable for workflows where repeated access or rapid sample handling is needed.
Blue push caps for 8 mm and 11 mm serum finish or snap‑top vials feature a thinned penetration area designed to reduce needle resistance and improve injection reliability. These caps are intended for single‑injection use only, as they do not reseal after puncture.
Clear push caps for 8 mm crimp‑top vials incorporate a fitted, resealable septum, offering improved sealing performance compared to non‑resealing push caps. For applications where evaporation control is critical, alternative closure options such as crimp caps may be more appropriate.
This subcategory also includes polyethylene plugs for 96‑well plate systems, designed for single‑use sealing of individual 700 µL glass inserts in plate‑based workflows. Each plug seals an insert independently, supporting sample containment during handling and analysis.
Selection of the appropriate push‑cap style depends on vial format, injector requirements, and whether resealing or evaporation control is needed for the application.
