Ultrathin Tungsten Needle

Ultrathin tungsten needle has advantages of high hardness and strong ductility. Also, it is not easy to break with durability. The diameter of tip of tungsten needle can reach micron level, which can be used to dissect and separate individual human cells, such as inner ear labyrinth cells. Some experts use 0.32mm tungsten wire to prepare ultrathin tungsten needles. They pre-machined the tips of fine tungsten wire blanks into needle-shaped, sickle-shaped, or hook-shaped needles. The diameter of the tip of these tungsten needles is generally 3 to 10 μm, and the smallest diameter can reach 1.5 μm.
