Specifications

PTFE-Tipped Syringes have a precision-machined plunger tip that forms a tight seal and enables the tip to wipe the barrel’s interior free of sample during operation. This feature is particularly useful for viscous or heterogeneous samples, because it reduces deposits that can cause the plunger to freeze.

Fitted Plunger Syringes feature a stainless steel plunger that is meticulously hand-fitted to its matching glass barrel, creating a liquid-tight seal. These syringes are ideal for homogenous samples that are not prone to precipitation or bonding with glass. Note: plungers cannot be interchanged or replaced if damaged.

Needle Gauge is the thickness of the needle. The gauge depends on the injector. When selecting a needle gauge, it is important to keep in mind the volume of the syringe and the dead volume of the needle.

  • Tapered Dual Gauge 23-26 or23s-26s (0.64 - 0.47 mm) - Durability of a 23 gauge and versatility of a 26 gauge for split/splitless and on-column injection
  • Single Guage 23 or 23s (0.64 mm) - Suitable for Merlin Microseal septa, packed column injector ports and split/splitless injector ports
  • Single Guage 26 or 26s (0.47 mm) - Suitable for packed column injector ports and split/splitless injector port

Needles with an 's' following the gauge are more durable, with a thicker needle wall and smaller id bore.

Needle Terminations are available in fixed or removable, with various tip styles:

  • Fixed (cemented) – Economical, reproducible injections for autosamplers
  • Removable needle – One syringe fixed – many methods, simplicity of fixed needle, but needle can be replaced if damaged or clogged

Needle Tip Design

  • Cone Tip (HP Tip, Point Style AS) - Proprietary design required for Agilent autosamplers for optimal performance and reliability by reducing septum coring
  • Bevel Tip (Point Style 2) - General purpose; excellent choice for transferring liquids from ampoules or vials. For manual GC injections, a beveled tip is preferred for optimum septum penetration and to prevent septum coring.
  • Side Hole (Point Style 5) - Recommended for thin gauged septa or large volume injections
