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.
- Single Gauge 22/22s (0.71 mm) - Suitable for HPLC valves and pipetting liquids
Needles with an 's' following the gauge are more durable, with a thicker needle wall and smaller id bore.
Needle Terminations are available fixed, with various tip styles:
- Fixed (cemented) – Economical, reproducible injections for autosamplers
Needle Tip Design
- LC Tip (Point Style 3) - For HPLC injections and sample pipetting, the blunt tip style 3 is preferred. The blunt tip has chamfered and polished edges that eliminate damage to the valve's rotor seal and stator face. This style can also be used for pipetting liquids.
