Syringe
Syringe Selection Guide
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.
Syringe Style
Fixed Needle Removable Needle
• Better option for experienced users or for applications requiring • Better option for inexperienced users
trace sample levels • Reduce cost if used in precipitation of salts or in situations in
• Recommended for use with an autosampler because the which it may bend easily (such as thick septum ) Available for
probability of needle bending is minimal many methods by changing needles
• Minimal sample carryover
Gas Tight
• For Luer Lock needles and fittings
• Specifically designed to install and secure Luer Lock needles easily
Needle Tip Style
Cone: Autosampler Bevel: Manual Injection
The cone-shaped needle tip is specially developed to withstand The standard general-purpose needle tip style supplied with many
multi- injection demands and improve septum lifetime when used syringes is a 20 ° bevel tip. It is the preferred option for manual
with an autosampler. The cone design effectively “parts” the sep- injection when piercing the septum in exactly the same place is
tum during piercing instead of cutting it, as would a bevel needle. difficult. The bevel tip is designe d for optimum septum penetra-
tion and prevention of septum coring.
Side Hole Dome
Samples are filled and dispensed through the side hole , eliminat-
ing septum plugging of the needle. Ideal for large-volume gas
injections. The solid domed tip minimizes septum damage.
Plunger Style
PTFE Tipped Plunger
• PTFE Tip enables gastight analysis
• Suitable for both liquid and gas samples
• Ideal for analysis of highly viscous liquid because it reduces the possibility
of the plunger sticking due to micro particles (samples should have no
effects with PTFE)
• Plunger is replaceable
