Glenco® Double-Action Syringes

The Double-Action Micro syringes are most widely recognized for their superior balance and the reduced heat transfer from your hand to your sample. They represent the ultimate sample injection syringe for both GC and HPLC use.

These syringes feature:

Superior Balance Reduced Heat Transfer Reinforced Plunger Assembly Precision Upper Guide Chamber Fixed or Removable Needles

Many syringes not specifically designed for chromatographic applications are delicate instruments, easily damaged when used with valves and fittings. We have overcome this problem with the double-action plunger guide. An enlarged upper guide chamber, a large plunger upper shaft and Teflon® guides combined with a precision syringe lower body produce the ultimate chromatography syringe.

The upper body improves the balance of the syringe by moving weight away from the needle. This same shift in the center of gravity allows you to hold the syringe by the upper body to prevent your hand from warming the sample contained in the precision syringe. The Teflon guides provide for smooth, positive injections, reducing any injection errors.

The needles supplied with these syringes are sharp with a deflected point; this prevents the hollow bore of the needle from contacting the septum as the need is inserted. Since the needle bore does not contact the septum, it cannot cut a "core" from the septum which could either become lodged in the needle and plug it or fall into your solvent container or injector. Regular non-deflected needles also cut larger holes in septa; this reduced the lifetime of the septa (when compared to the deflected point needles) and keeps them from sealing as well when the needle is removed.

Point deflection is not an issue for hypodermic needles since skin is a more stringy material than silicone and skin is also self-regenerating.

Replacement needles are available for the removable needle syringes. These may be used to change the style of needle on the syringe or to replace a bent or clogged needle. A list of the available needles is available here. All of these syringes are stocked with sharp, non-coring needles, generally any of the replacement needles at no extra charge if the request is made at the time of the order.

Because the lower precision syringe body uses a lapped plunger to provide a 100 psi seal, the plungers and glass bodies are not individually replaceable.

These syringes are sold for laboratory use only. They are not sold for medical, veterinary, or other uses.
