Bevel needle tip (Manual GC)

A 20° bevel tip is the standard general purpose needle tip style supplied with SGE syringes. This style is designed for optimum septum penetration and prevention of septum coring.

Plunger- in- Barrel

Volumes > 1µL

Sheathed/Bevel needle tip (Manual GC)

The same as the bevel tip, except a 0.7mm OD reinforcing sheath is silver soldered over the standard needle to within 10mm of the tip. The sheath provides exceptional strength to the needle.

Plunger- in- Needle

Volumes < 1µL (capillary column applications)

HPLC needle tip (HPLC)

HPLC valve injection syringes have 90° square tip needles with chamfered and polished edges to eliminate damage to the valve's rotor seal and stator face. This needle tip is also suitable for the pipetting of liquids.

Side hole domed needle tip (Large Volume Injection)

Liquid samples are filled and dispensed through the side hole. The solid domed tip minimizes septum damage.

PTFE coated needle tip (TLC/Gel Spot Plating)

The needle has a 90° square tip and a 20mm long film of PTFE coated over the tip. Ideal for dispensing aqueous samples without wetting the outside of the needle.
