The Hamilton Medical 81243 syringe: a precision tool for demanding applications
The Hamilton Medical 81243 syringe is part of the 1700 series, a range specifically developed to offer exceptional performance in gas handling. This series is renowned for its ability to maintain a perfect seal, even under relatively high pressure conditions. With a net volume of 500 µL, it meets the needs of laboratories performing precise dosing of small quantities of fluids, while ensuring excellent reproducibility.
The 81243 model stands out in particular for its Luer Tip connection with a cemented needle, ensuring a solid and reliable connection and minimising the risk of leakage or fluid loss. This 22-gauge needle is designed with a style 5 tip, i.e. a conical side opening that allows for more controlled dispensing, which is particularly useful for certain analytical or automated dosing techniques. Its length of 51 mm makes it compatible with many automated injection or sampling systems.
The internal construction of this syringe is another key factor in its reliability. The materials used for the fluid path – stainless steel (SST), borosilicate glass and PTFE – guarantee maximum chemical inertness, reducing the risk of cross-contamination or reaction with the substances being handled. Although not autoclavable, this syringe can be sterilised by gas, making it suitable for environments requiring a high level of sterility.
In addition, the syringe body is designed with an internal diameter of 3.26 mm and an external diameter of 7.75 mm, ensuring a good grip and precise control of the piston. The maximum pressure supported by the device is 700 psig (48.3 bar), making it suitable for use in more demanding pressure conditions than standard syringes. Its operating temperature range is 10°C to 50°C, allowing for stable use in most laboratory environments.
The Hamilton Medical 81243 syringe is the preferred choice for laboratories seeking precision, reliability and compatibility with automated or manual dosing systems. Its careful design and high-quality materials make it an indispensable tool in fields such as gas chromatography, environmental analysis, pharmaceutical research and industrial quality control.
