注射器 SYRINGE

注射器柱塞可能或多或少難以操作，以控制方式輸送或注射液體或凝膠制劑。注射器用于使用柱塞以受控方式輸送或注射液體或凝膠制劑。激活柱塞所需的力（表達式或抽吸）取決于各種因素，如注射器形狀、尺寸、配方粘度和速度。機械測試儀可用于激活柱塞，同時記錄所需的力水平，以根據內部液體或凝膠的特性激活柱塞。有關注射器結構本身的信息可以從這類測試中獲得。

Syringe plunger can be more or less difficult to operate to deliver or aspire liquid or gel formulation in a controlled manner. A syringe is used to deliver or aspire liquid or gel formulation in a controlled manner using a plunger. The force (expression or aspiration) required to activate the plunger depends on various factors such as the syringe shape, dimensions, the viscosity of the formulation and the speed. A mechanical tester can be used to activate the plunger while recording the required level of force to activate it in function of the properties of the liquid or gel inside. Information on the syringe construction itself can be gained from this type of test.
