注射器柱塞可能或多或少难以操作，以控制方式输送或注射液体或凝胶制剂。注射器用于使用柱塞以受控方式输送或注射液体或凝胶制剂。激活柱塞所需的力（表达式或抽吸）取决于各种因素，如注射器形状、尺寸、配方粘度和速度。机械测试仪可用于激活柱塞，同时记录所需的力水平，以根据内部液体或凝胶的特性激活柱塞。有关注射器结构本身的信息可以从这类测试中获得。

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.
