Low Force Insertion of Lancets and Needles Allows greater control while minimizing discomfort and stress for subjects in pre-clinical studies. GentleSharp adds directed, low-frequency, oscillatory motion to the needle as it is inserted. The resulting micro-vibrations help the needle puncture and glide through tissue more smoothly with less resistance. Since less force is applied to the tissue during needle puncture, the subject experiences less stress from the blood sampling procedure. Key Advantages Lower and less variability of stress hormone level over repeat sampling. Less risk of vasoconstriction in subjects. Reduced number of subjects necessary for longitudinal research studies. More humane blood sampling procedure.
