Needle-free Lasette Produced with all-sided quality control system of the Cell Robotics Company of United states, the lasette pain-free lancing device has got the certificates of FDA, CE and CDRIH IEC with many patents. The Needle-free Lasette uses Erbium YAG laser light , with wavelength of 2.94mm, to create a small opening on the finger for drawing capillary blood. In 1/40000 second period, the temperature of the light get 1000°C to vaporize water molecules in the skin but ensure of risk of cauterization of the delicate capillary vessels. The Needle free lasette makes a breakthrough in clinical use for capillary blood collection and adopted popularly in the western countries. No Needle, No Risk 1, No cross-contamination issues. 2, No sharps disposal; Initially feels like a lancet or less. 3, Not a puncture wound ­ better flow for larger samples. 4, Blood flows longer before clotting. No lingering soreness or "Throbbing".
