Manual Autosampler or Instrument Syringes
If a syringe is being used by hand, a manual syringe should be selected. If a syringe is installed in an AOC autosampler then choose the appropriate syringe and volume to suit your instrument and application. Shimadzu autosampler syringes are speci cally designed to meet instrument dimensional speci cations, have an accuracy of better than ± 1 % and are designed for precise, worry-free overnight sampling.
Needle Tip Styles
Cone: GC Autosampler
LC: HPLC
The cone shaped needle tip is specially developed to withstand multi injection demands and improve septum lifetime when used with the AOC autosampler. The cone design effectively “parts” the septum during piercing instead of cutting it, as would a bevel needle.
These needles are used for LC and HPLC valve injection and have a 90 ° square tip with rounded and polished edges. This eliminates damage to the valve's rotor seal and stator face. This needle tip style is a good choice for general liquid dispensing.
Bevel: Manual GC
Side Hole Dome:
The standard general purpose needle tip style supplied with many Shimadzu syringes is a 20 ° bevel tip. It is the preferred option for manual injection where piercing the septum in exactly the same place is dif cult. The bevel tip is designed for optimum septum penetration and prevention of septum coring.
Samples are lled and dispensed through the side hole eliminating septum plugging of the needle. Ideal for large volume gas injec- tion. The solid domed tip minimizes septum damage.
Dome:
This style needle is recommended for use with predrilled septa. The tip is rounded and polished to help septum penetration.
