GC Manual Syringes

If you want reproducible injections at an economical price: Choose a fixed needle syringe (N or LTN suffix). N denotes an epoxy cemented 304 stainless steel needle inserted in the syringe barrel to a depth corresponding exactly to the zero graduation. LTN denotes a cemented Luer tip needle. Fixed needle syringes should not be heated above 50 °C.
If you like the simplicity of a fixed-needle syringe, but want to replace damaged needles, or change gauges to suit your applications: Select a syringe with a removable needle (RN). RN syringes allow easy replacement of damaged needles in the field. The needle seats to the zero graduation mark, providing the same characteristics as cemented needles. RN syringes should not be heated above 115 °C.
If you need a knurled hub: A knurled hub (KH) syringe creates a leak-tight seal between barrel and needle and may be retightened to compensate for wear. The male Luer accommodates a spacer for defined depth insertions. Exclusive to 7000 Series syringes.
If you want an autoclavable syringe with easy, fast needle replacement: Choose a syringe with a Luer Tip (LT). LT denotes a ground glass Luer tip suitable for mounting chromatographic needles. Order needles separately. Metal hubbed needles are not recommended. LT syringes can be autoclaved at 121 °C. Remove the plunger during sterilization.
If you like the Luer needle attachment, but need the security of a locked needle attachment: It is available with PTFE Luer Lock syringes (TLL). PTFE Luer Lock has a screwable PTFE center male Luer to hold your needle tightly in place. TLL used with 1000 Series provides an essentially inert syringe. Order needles separately. Metal or PCTFE hubbed needles can be used. Syringes with TLL connectiions shoyuld not be heated above 50 °C.
If you have problems with bent plungers: Plunger guides (WG suffix) reduce the expense of replacing or repairing syringes with bent plungers. Especially useful on syringes with small diameter plungers.
If you require precise control of sample size: Chaney adapters (CH suffix) ensure consistent sample delivery. You will know the sample size is right every time.

Note: Hamilton uses the most chemically resistant adhesive available to cement the needles into these syringes. Prolonged contact with some solvents, however, can cause the adhesive to deteriorate. After making your injections, thoroughly rinse the syringe with distilled water and allow it to air dry. Do not soak your syringe with any solvent for more than three minutes. In cases where prolonged use of strong solvents is necessary, you may wish to use an RN syringe.
