SGE- Needle selection - Analytical Columns

	Cone Tip • minimizes septum coring for GC autosampler use
	Bevel Tip • standard general purpose needle tip style for dispensing liquids • ideal for GC analysis with manual injection
	Dual Gauge • narrow gauge at front end for on column injection • wide gauge to increase strength for autosampler use
	LC Tip • the square tip needle prevents damage to the valve’s rotor seal and stator face of the injector • suitable for the pipetting of liquids
	Dome Tip • rounded and polished tip to facilitate septum penetration
	Side Hole / Dome Tip • liquid sample is filled and dispensed through the side hole • recommended for large volume GC injection
	PTFE Coated Tip • ideal for dispensing aqueous samples without wetting the outside of the needle
	Sheathed / Bevel Tip • same as the bevel tip, except a 0.7mm OD reinforcing sheath is silver soldered over the needle to within 10mm of the tip • sheath provides exceptional strength to the needle
