Hamilton Company provides a series of tungsten wires with varying outer diameters for removing clogs that form inside of small gauge needles. Each package of wire comes with 10 seven inch wires. A biodegradable cleaning concentrate is also available to help remove tenacious residues. For 7000 series syringes a heated syringe cleaner is available. The syringe cleaner heats the plunger and needle to 370°C and vaporizes any trapped organic solvents.
