A range of standard and custom CTC autosampler syringes manufactured to achieve the highest level of accuracy and precision possible. These C-Line syringes also feature a new sealing system based on a novel metal spring for working with enhanced tightness, excellent performance over a large temperature range and temperature gradients, increased lifetime compared to traditional headspace syringes and increased accuracy and reproducibility of headspace GC analysis. Syringes in this category are either 700 and 7000 series Microliter or 1700 and 1000 series Gastight syringes. Microliter syringes have a stainless-steel plunger that is hand fitted to the glass barrel and are designed for liquid sampling. Gastight syringes have a PTFE plunger tip that creates a tight connection between the syringe barrel and plunger, allowing for liquid or gas sampling.
Made of PTFE/polymer for better temperature stability
Features flange for easy installation
Adjustable plunger button for plunger tip clearance
Hub and needle design for zero carryover
C-Line Syringe Terminations
Fixed Needle (FN) features a direct attachment of the needle to the barrel and eliminates contact between the sample solvent and the adhesive reducing carryover
Special Cemented Needle (SN) shares the same characteristics as a standard cemented needle syringe but comes in a special length
Knurled Hub (KH) with removable plunger/needle assembly, knurled hub is used exclusively on the 7000 series syringes
Headspace Syringe Terminations
Luer Tip Cemented Needle (LTN) for mid volume syringes
Needles cemented into the glass syringe barrel at a point corresponding to the zero graduation mark, hence dead volume is limited to the internal volume of the needle
Needle gauge determined by the syringe volume and are not user-selectable
Needle Point Styles
Point Style 2: Sharp, beveled, curved, non-coring needle point recommended for septum penetration
Point Style 5: Conical needle with side port for penetration of septa, thin-gauged vinyls and plastics without coring
Point Style AS: Special conical style needle point used on autosampler syringes the non-coring needle point is recommended for septum penetration
