Agilent, 5181-8810, ALS Syringe, 5 µL, fixed needle, 23-26s/42/cone, 6/pk

Agilent 5 µL GC autosampler syringes deliver microliter-scale liquid samples into compatible gas chromatograph inlets. The fixed, tapered 23–26s gauge needle has a 42 mm length and a conical point, supporting repeatable penetration through appropriate injector septa. A stainless-steel plunger tip is used with the syringe barrel. The recommended injection volume is 0.5–4 µL, providing a working range below the nominal 5 µL capacity. The six-syringe package supports routine replacement when injection precision, needle condition, or plunger movement deteriorates. Before use, confirm autosampler syringe geometry and inlet compatibility, then select a sample solvent and injection volume appropriate for the analytical method. Avoid bending the needle or forcing a sticky plunger; inspect for deposits and leaks during maintenance. Consistent syringe conditioning, needle handling, and sample preparation help limit carryover and variation in GC peak areas.
