S-Line syringes are the cost-effective choice for CTC PAL autosampler applications. S-Line syringes deliver great performance in everyday use for HPLC injections at an exceptional value. The Gastight version of the S-Line syringe is an ideal choice for HPLC sample injections. It incorporates a precision-machined PTFE plunger tip which creates a leak-free seal. With the tight fit in the glass barrel, the tip wipes the interior of the syringe barrel free of sample, minimizing sample carryover. This feature is particularly useful with heterogeneous samples as it reduces the chance that a deposit will occur and cause the plunger to freeze.
