Hamilton 701 SN syringe (ref. 200740): a precision solution for gas chromatography
The Hamilton syringe ref. 200740 embodies the brand's expertise in analytical microinjection, particularly in the demanding field of gas chromatography (GC). Designed for PAL GC and Combi PAL Headspace autosamplers, this syringe has been developed to offer optimal precision and reproducibility, meeting the most stringent standards of analytical laboratories.
This model is part of Hamilton's 700 series, renowned for its robustness, reliability and precision components. It offers an injection volume of 10 µL, ideal for analyses requiring small sample quantities with maximum accuracy. The 700 series uses a design optimised for compatibility with automated injectors, ensuring consistent performance and perfect alignment in autosampler systems.
The needle on the 701 SN syringe (ref. 200740) is cemented, meaning that it is permanently attached to the syringe, reducing the risk of leakage or accidental disconnection. It has a 32 gauge, giving the assembly a very fine diameter suitable for delicate injections, while minimising potential damage to the column. The tip style is 45°, an ideal choice for direct injections into chromatograph septa without causing damage or contamination.
The materials used in the manufacture of this syringe are carefully selected for their strength and chemical inertness. The fluid path is made of stainless steel (SST) and borosilicate glass, ensuring perfect compatibility with a wide range of solvents and samples. These materials are also chosen to minimise adsorption or interaction with sensitive compounds, thus guaranteeing accurate analysis results.
In terms of thermal resistance, the 701 SN syringe (ref. 200740) can withstand temperatures between 20°C and 50°C, making it suitable for most laboratory working conditions. Although it is not autoclavable, it can be sterilised by gas, allowing it to be used in environments requiring strict sterility without compromising the integrity of its components.
Precision is also ensured thanks to a standard dead volume of only 0.67 µL. This feature reduces sample loss and the risk of cross-contamination between two successive injections. The internal (0.11 mm) and external (0.24 mm) dimensions of the needle ensure controlled flow, suitable for automated systems and high-precision applications.
The syringe integrates easily into the workflows of analytical chemistry, quality control and pharmaceutical research laboratories, and is a trusted choice for all professionals seeking reliability and accuracy in their GC analyses.
