使用蠕动泵处理细胞敏感泵送 用 Ismatec Pro-280 泵头泵送活细胞 连接 Pro-280 泵头与 BVP 或 MCP 蠕动泵 驱动器后，所形成的系统 可用于持续泵送活细胞，同时能最大限度减少细胞损伤。该系统设计独特， 适用于生物技术应用。该系统已在实验室以及高达 30 升的小型生产反应器中经过测试。 它是如何工作的？ 泵头 Pro-280 带有 2 个球面滚轴，管床呈凹形。在滚轴完全挤压并闭合泵管之前，细胞可以逃入管壁间隙，这样既不会被“压扁”也不会被损坏。 动物细胞培养应用中...

流体泵—粘性流体处理特性 粘性流体的泵送有一定难度。选择泵时，流体粘度应是必要考虑因素。通过观察粘性流体在受力时的行为，可以更好理解粘度的影响。 牛顿流体—无论剪切速率多少或如何搅拌，粘度都保持不变。随着泵速增加，流速按比例增加。具有牛顿行为的流体包括水、矿物油、糖浆、碳氢化合物和树脂。 假塑性流体—粘度随着剪切速率的增加而降低，但在典型泵送系统中其初始粘度足以阻止流动。典型的假塑性流体包括凝胶、乳胶漆和乳液。 膨胀性流体—粘度随着剪切速率的增加而增加。泵送膨胀性流体的初始阶段，泵可能会停...
