HOLLOW MICRONEEDLE HUB
Hollow Microneedle Hub is a 3×3 microneedle array with a luer-slip female hub connectible to typical syringe. This is a good first prototype for conducting intradermal trials. The height of the microneedles is 1,000um and the distance between the microneedles is 1,000um. The lumen of phentermine is 100um – 150um in diameter and the size of the microneedles is 200um x 200um or 300um x 300um.
