Precision and robustness: the Hamilton 80357 syringe
The Hamilton 80357 syringe stands out as a benchmark tool in laboratories where precision and reliability are essential. Designed for chromatography or automated sampling applications, this syringe from the Microliter 700 series is optimised to deliver a nominal volume of 10 µL with a high level of repeatability. Its robust design and compatibility with Agilent autosamplers make it a trusted choice for analysis professionals.
The 80357 model features a removable needle (RN) with an AS conical tip style, specially designed for automatic injectors. This tip shape ensures precise positioning and unobstructed penetration into septa or sampling systems. The 23s gauge needle is 43.4 mm long, an ideal size for a variety of analytical applications.
The syringe is made of high-quality materials: a borosilicate glass body and a stainless steel (SST) fluid path. This combination guarantees chemical inertness, mechanical strength and ease of cleaning, while allowing use in sterile environments. It is designed to withstand temperatures ranging from 10°C to 80°C and high pressures up to 2000 psig (137.9 bar), making it suitable for demanding protocols.
Another important advantage is that the syringe is autoclavable and gas sterilisable, allowing it to be used in working environments that require perfectly aseptic devices. The standard dead volume of the needle is reduced to 0.46 µL, which limits sample loss and helps improve dosing accuracy, a fundamental criterion in very small volume analyses.
The dimensions of the cylinder are also optimised for accuracy: an internal diameter of 0.485 mm and an external diameter of 6.60 mm, ensuring good handling while maintaining excellent measurement accuracy. The needle has an internal diameter of 0.34 mm and an external diameter of 0.64 mm, offering a good compromise between fineness and robustness.
The product can be easily integrated into existing systems without the need for a specific adapter, making it practical and economical. Whether for research laboratories, environmental testing facilities or clinical applications, the Hamilton 80357 syringe is a reliable, accurate and durable solution for microinjection needs.
