Assessing the injectability of a viscous compositions, a standard 10 ml duoNEX (Zarys, Zabrze, Poland) syringe and Sterican ® (14 and 18G) needles assembly are employed in a controlled test procedure. The viscous liquid samples maintained undergo an injection process using a specified syringe and needle configuration at 23 °C. The force required to inject the liquid through the needle is measured using a force measurement device which is an Instron 3366 (United Kingdom) with a 500 N load cell, at crosshead speed of 10 mm/min.
