250 µL, Gastight Syringe, Cemented Needle (N), PN: 84887 Details

Hamilton's 1800 series, Gastight # 1825 Cemented Needle (N) Syringe is a reinforced plunger version of the 1700 Gastight syringe. This syringe also features a blue Syringe Holder attached to the flange. This unique component safeguards against any heat transfer from the barrel, ensuring accurate dispensing. The reinforced plunger provides crucial support to delicate small-volume plungers, preventing bending and maintaining injection integrity.

Common applications Analytical Chemistry, Gas Chromatography Mass Spectrometry (GC-MS)

Gastight Syringe with a Syringe Holder Design

  • Integrated blue holder on the flange prevents heat transfer to the syringe barrel.
  • Prevents dispense inaccuracies from sample heating.

Reinforced Plunger Style

  • Engineered to safeguard delicate plungers in small volume syringes, preventing bending of their fine plunger wires.
  • Increases the overall durability of the syringe, providing a reliable instrument for repeated use.
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.
