Description General description S-Line syringes deliver exceptional performance for everyday use in HPLC autosampler injections at a great value. The C-Line syringe minimizes the potential for bent needles with a keyed flange design. X-Type syringes are designed for sensitive LC samples (i.e. proteins, peptides, phospholipids, smaller amines, etc.) with a specially coated needle and inner syringe barrel to minimize sample adsorption.
