The benefit of the Luer cap is its ability to dispense a precise amount of liquid in a controlled manner. This feature makes them especially suited to applications such as laboratory, analytical and pharmaceutical and educational and museum archiving. The precision dispensing of liquids is critical in labs for sample preparation and general analysis and testing. Luer caps are also useful for a range of hazardous materials including conservation adhesives, metal de-corroder and varnish remover. The materials used to make the Luer caps at Measom Freer are tested to ensure they can withstand usage within these circumstances and will continue to work reliably throughout their lifetime.
