Unistik 3 Extra Single Use Safety Lancets Unistik 3 Extra Single Use Safety Lancets are 21 gauge lancets with a 2mm depth penetration that are ideal for blood banks and laboratories. Unistik 3 Extra Single Use Safety Lancets are easy to use with a simple one-click action to activate the lancet. They use the unique Comfort Zone Technology (CZT) which has been shown in independent clinical testing to reduce pain for a more comfortable testing experience. CZT is comprised of eight raised pressure points on the patient end of the safety lancet which stimulate the nerve endings to produce a comfortable sensation which masks the pain sensation from the lancet. Unistik 3 Extra Single Use Safety Lancets feature an ergonomic design that gives healthcare providers complete confidence and control during the sampling procedure and a needle that retracts immediately after use to reduce the risk of needlestick injuries and cross infection. A lockout indicator shows when the device has been used to prevent accidental re-use of lancet. It also has an indicator to enable accurate positioning and a side-fire mechanism that allows the user to decide exactly when to activate the device and how much pressure to apply. Directions - Twist off and discard lancet cap - Press Unistik 3 against finger and press the release button - Dispose of the used Unistik 3 in a suitable sharps container
