Dual Needle Design - Air Needle pierces first
Dual Needle Design – Air Needle pierces first

The S 5250 Sample Injector with a sample capacity of 60 standard (12 x 32 mm) vials or 96 with a microtiter plate, is the smallest of the three autosamplers of the Sykam HPLC range. The small footprint of only 310 x 210 x 478 mm (HxWxD) in combination with excellent specifications and almost maintenance free mechanics makes this autosampler an ideal partner for automating not only Sykam HPLC systems but virtually any HPLC system that needs to be upgraded with an autosampler.

A speciality of the S 5250 autosampler is the double needle injection technique by which the outer needle or “air needle” pierces the vial septum before the sample needle enters the vial. This is a unique approach avoiding blocked injection needles and/or blocked injection valves. This allows the use of any type of vial septums and by which it adds to improved reliability of the chromatography system as a whole.
