Polymer Plunger Tip

  • A white polymer plunger tip effectively wipes the glass barrel, creating a leak-free seal.
  • Ensures a Gastight performance, suitable for liquids and gases.

S-Line Design

  • The Fixed Needle termination features an improved needle design for zero carryover and enhanced solvent compatibility.
  • Minimal drag force and optimal wear characteristics of the fitted plunger result in superior autosampler uptime.
Scientific Citations

  • Gastight Syringes Ensures Integrity of Environment Sensitive Catalysts (or Samples)

    For such, we utilize highly reactive catalysts that are in many cases air and moisture-sensitive. Gastight Hamilton syringes are essential to maintaining the catalyst integrity and, therefore, ensuring reproducible and trustable results.

FAQ

Can I order a replacement plunger for my syringe?

Most Gastight syringes have replacement plungers available under 'Accessories' on the product page, while Microliter syringes do not. 7000 series modified Microliter syringes have zero dead volume and a small plunger wire, but it's best not to remove the needle or plunger to avoid damaging the wire.
