ILS needle tip styles for microsyringes

Needle Tip a Needle Tip “a”

This tip is designed for optimum penetration of the septa and prevents septa coring.
The 17° bevel is proven standard. In addition our electro tapered tip minimizes
the necessary piercing force and diameter of the injection channel.


Needle Tip b Needle Tip “b”

This tip has a 90° bevel for precise pipetting. This design releases drops completely,
for maximum reproducibility. It is widely used for HPLC sample injection.


Needle Tip c Needle Tip “c”

This tip has been specially designed for autosamplers in routine applications.
The electro tapered tip and the polished 90° square end eliminate burrs.
It is ideal for PTFE laminated seals and regular septas.


Needle Tip d Needle Tip “d”

Tip “d” is equipped with a side opening for dispensing and filling.
This design avoids plugging and minimizes septum damage.
It is ideal for thicker septa and recommended for headspace analysis.
