生物安全柜前窗口操作高度测量结果不确定度评定

Evaluation of Uncertainty in Measurement Results of Height of Front Window of Biosafety Cabinet

生物安全柜是微生物实验室的必需品,广泛应用于医疗卫生、制药、科研等行业,其不仅能对操作者提供保护措施,还能在进行细菌培养时提供无菌无尘的工作环境。为保证操作人员在操作生物安全柜时不受细菌的侵害,生物安全柜的各项指标需要定期进行校准。本文对生物安全柜前窗口操作高度测量结果进行不确定评定,给出测量结果的不确定度。

The biosafety cabinet is a necessity of microbiological laboratory,which is widely used in medical and health,pharmaceutical,scientific research etc.It can not only provide protection measures for operators,but also provide a sterile and dust-free working environment for bacterial culture.In order to protect operators from bacteria when operating biosafety cabinet,the indicators of biocabinet need to be calibrated regularly.This article evaluated the uncertainty of height of front window of biosafety cabinet,provided the uncertainty of measurement results.
