关键因素：接头杀菌 在为应用选择接头时需考虑几个重要因素：尺寸、连接方式、化学相容性以及认证/审批要求。每个因素都具有挑战性。然而，在许多应用中，还需要额外考虑灭菌适应性，这同等重要。 要去除污染材料和设备表面的微生物（包括产芽孢和非产孢细菌、病毒、真菌和原生动物），使用前灭菌是必要的过程。如果未成功消灭这些微生物，可能会导致潜在的健康危害、研究污染和实验变数。灭菌常用于制药、研究和食品应用领域。这些领域中的大多数设施都制定了灭菌指南，以规定任何特定工艺中的各种材料处理方式，从而防止产生有...

泵送粘性流体 粘性流体的流动速度比类水流体慢得多，原因包括： 流体比水更具抗流动性。 粘性流体与管壁之间的摩擦力比水大。 蠕动（泵管）泵是泵送粘性流体的理想选择。请按照以下步骤操作以确保蠕动泵系统达到最佳效率。 减慢泵的速度， 流体只会以特定流速进入泵头。一旦达到这个流速，不会再因电机速度的增加而加快。随着粘度增加以及泵管尺寸减小，系统的最大有效泵送速度将降低。 选择的泵管尺寸应大于 泵水所需的尺寸。选择 100 rpm 时各种粘性流体的近似流速，这适用于不同尺寸的 Masterflex®...
