Cone (for Autosampler Injection)
The cone-shaped needle tip is specially developed to withstand multi injection demands and improve septum lifetime when used with an autosampler. The cone design effectively "parts" the septum during piercing instead of cutting it, as would a bevel needle.
26G: For sample preparation steps
23G: For injection into the GC/GCMS
85 mm length: For transferring liquid from ≥ 20 mL vials
Bevel (for Manual Injection)
The standard general-purpose needle tip style supplied with many syringes is a 20 ° bevel tip. It is the preferred option for manual injection when piercing the septum in exactly the same place is difficult. The bevel tip is designed for optimum septum penetration and prevention of septum coring.
Side Hole Dome
Samples are filled and dispensed through the side hole, eliminating septum plugging of the needle. Ideal for large-volume gas injections. The solid domed tip minimizes septum damage.
