FAQs

Q1: Why do I need a pointed tip needle for Gas Chromatography (GC)?

A1: Gas chromatography (GC) injection ports are sealed with thick, high-density rubber septa to maintain internal gas pressure. A flat or blunt needle will core (cut out a small chunk) the rubber, causing leaks and destroying the septum. A pointed tip slices cleanly through the rubber and lets it reseal perfectly after the needle is withdrawn.

Q2: What is the benefit of the PTFE (Teflon) plunger tip?

A2: In capacities from 10μL upwards, our plungers feature a precision PTFE tip. PTFE is highly chemically inert and self-lubricating. It creates a flawless “gas-tight” seal against the glass barrel, ensuring that high-pressure carrier gases from the GC machine do not blow the sample backward up the barrel.

Q3: How is the 1μL syringe different from the 100μL model?

A3: For ultra-micro volumes like 1μL or 5μL, standard plungers leave a tiny amount of liquid in the needle (dead volume). To achieve absolute accuracy, our ultra-micro models use a specialized plunger wire that travels all the way down to the very tip of the needle, ensuring 100% zero dead volume injection.

Q4: Can I use this syringe for High-Performance Liquid Chromatography (HPLC)?

A4: While pointed tips are specifically engineered for penetrating GC septa, they can be used for certain HPLC applications. However, for HPLC rheodyne valves, a flat-tip (blunt) needle is generally recommended to avoid scratching the internal stator of the injection valve.
