操作方法
3)吸取1ml制备好的菌悬液,置于支含有9ml无菌水的试管内,这样就稀释了10倍,也就是10-2。
(4)从支试管内(10-2)吸取1ml注入第二支含有无菌水的试管内,这样就稀释了100倍,也就是10-2。
(5)用同样方法操作,直至稀释至10-5-10-6。
(6)分别精确吸取10-5-10-6各稀释度菌液0.2ml加入编好号的空无菌平皿中,同稀释度重复做三个平皿。
(7)将已溶化并冷却至45℃的琼脂培养基倒入上述各平皿内,轻轻旋转使培养基与菌悬液充分混匀,凝固后倒置于37℃或38℃度恒温箱中培养24-48小时,观察平板上菌落生长和分布情况
产品简介
微生物限度检测仪厂家,微生物限度过滤系统:QYW-300B微生物限度检测仪(微生物薄膜过滤器)采用不锈钢金属材料制成,配有内置隔膜液泵,不需外接抽滤瓶,液体直接通过隔膜液泵排除,减少了抽滤瓶使用上的繁琐,避免了连接不好造成抽滤速度慢等缺点。
微生物限度检测仪厂家,微生物限度过滤系统:将供试品注入微生物限度培养器内,通过检验仪自带内置隔膜液泵负压抽滤,将供试品中微生物截留在滤膜上,用取膜器取出滤膜,转移至配置好的固体培养基上,菌面朝上,平贴。盖上盖子形成封闭的培养盒,置于相应的恒温培养箱内培养并计数。
制药:纯化水、注射用水、眼用制剂、原料药、胶囊、生物制品、片剂、口服制剂;
食品:纯净水、矿泉水、饮料;
化工:各种需测试微生物水样;
化妆品:各种用水及产品;

公司介绍
Traditional Chinese medicine yinpian is a special type of medicine, which can be taken orally directly or used as a preparation after formulation. Microbial contamination, as one of the main sources of exogenous contamination, is an important factor affecting the quality and safety of prepared slices of Traditional Chinese medicine, and has attracted much attention at home and abroad. At present, the study on microbial control of traditional Chinese medicine or plant medicine mainly includes two aspects: first, the total number of aerobic bacteria and yeast fungi in the sample are used as indicators to detect and evaluate the overall contamination degree of the sample microorganisms; The second is to test the specified control bacteria in the samples, such as bilisal-resistant gram-negative bacteria, Salmonella, Escherichia coli, pseudomonas aeruginosa and Candida albicans, so as to control the introduction of exogenous pathogenic factors
