Laboratory purification needs to be good at use and management, so as to better play its due role. So how to use and manage laboratory purification? Let's take a look with Xiaobian. I hope the following information will be helpful for you to understand laboratory purification.
Laboratory Purification
(1) Laboratories should be kept clean and tidy, and only necessary testing equipment such as alcohol lamp, alcohol cotton, matches, tweezers, inoculation needles, inoculation rings, glass pencils, etc. should be stored in the laboratory. Don't put anything unrelated to the test.
(2) The indoor inspection equipment and benches and tables should be kept in a fixed position and not be moved freely.
(3) wipe the workbench, doors, windows, tables, chairs and ground with 2% carbonic acid solution every 2 to 3 weeks, then disinfect the air with 3% carbolic acid aqueous solution, and then the ultraviolet lamp is killed for half an hour.
(4) Regular inspection of indoor air sterility, the number of bacteria should be controlled below 10, found that does not meet the requirements, should be immediately thoroughly disinfected and sterilized.
Aseptic chamber aseptic degree determination method: Take common agar plate, improved Martin medium plate 3 (plate diameter is 9 cm), placed in the laboratory working position, open cover exposure for half an hour, and then inverted for culture, the total number of bacteria measured should be placed 37 C incubator culture for 48 hours. The number of fungi measured should be incubated in a temperature box of 27 for 5 days. The total number of bacteria and moulds should not exceed 10.
(5) Before sterilization, all articles should be placed in the place where they are operated (except for those to be examined). Then the ultraviolet lamp should be turned on for sterilization for 30 minutes. When the time is up, the ultraviolet lamp should be turned off for use.
(6) Before entering the laboratory, sterilized overalls, hats and shoes must be replaced in the buffer room.
(7) The operation should be carried out in strict accordance with the laboratory purification operation regulations, with less speech and no noise in order to keep the environment sterile.
