微量移液器在抗生素效价测定中的应用

Application of Micropipettor in the Measurement of Antibiotic Titer

目的:提高抗生素效价测定中加液的准确性,降低由于视觉误差造成测定结果可信限率的偏大.方法:使用微量移液器定量加液代替毛细管滴加药液。结果:微量移液器加液法测得结果的可信限率明显低于毛细滴管加液法。结论:微量移液器加液法可用于抗生素效价的测定。

Objective： Improving the accuracy of adding solution in the t of antibiotic titer , lowering the visual error which can lead a high result in confidence limit rate, Methods： Using micropipettor instead of capillary in adding liquid. Results ： The confidence - limit rate in micropipettor is obviously lower than that of capillary, Conclusion ： Micmpipettor can be used in the determination of antibiotic titer.
