Automatic suction filter Purpose: it is used for microbial limit test, sterility test or detection of pathogenic bacteria in sewage by membrane filtration method of aqueous solution samples (in accordance with Chinese Pharmacopoeia, GB 159822012 and WS 507-2016) Applicable samples: (1) Surface, neutralization eluent of two hand sampling swab (2) After disinfection and washing of endoscope, neutralize eluent recovered after injection (3) Disinfectant in use Compound neutralization eluent for membrane filtration 50ml compound neutralization eluent - endoscopic microbial limit test after disinfection with disinfectant 10ml compound neutralization eluent + rinsing solution (residual sample in rinsing cup, filtered) - microbial limit test of sterilized object surface and hands sampling 9ml compound neutralization eluent + rinsing solution (residual sample in rinsing cup, filtration) - microbial limit test of disinfectant in use

Purpose: It is used for the cultivation of anaerobic bacteria and provides anaerobic gas environment. Purpose: anaerobag ™ Anaerobic air bag (500ml) is mainly used for the culture of clinical anaerobic bacteria. This is a complete anaerobic bacteria isolation and culture scheme: 1. Anaerobic gas production bag (bag): reduce the oxygen in the closed environment of cul culture bag or anaerobic culture tank / box to < 0.1% within 1.5 hours to facilitate the growth of anaerobic bacteria. Anaerobic gas environment: O2 < 0.1% (within 1.5 hours), 7-15% CO2 (within 2 hours); Rapid oxygen consumption is conducive to the survival of anaerobic bacteria. 2. Anaerobic indicator: indicates whether the anaerobic conditions in the closed environment meet the standard; 3. Matched special plastic culture bag (cul culture bag) and sealing clip; 4. Supporting anaerobic culture tank / box; 5. Supporting various anaerobic culture media, such as Brucella blood agar, CCFA, lkv agar, BBE agar, can agar, etc. advantage: High quality and low price The operation is simple, and the specimens are cultured as they arrive No space, no need for ventilation Anaerobic culture preparation: Materials: take culture medium, anaerobic gas production bag (bag), anaerobic indicator, cul culture bag or anaerobic culture tank / box. Operation steps: 1. Inoculate specimens and strains in the culture medium in advance and put them into cul culture bag in time;

Put two inoculated 90mm agar media into the culture bag. If only one 90mm agar medium is inoculated, put another 90mm empty culture dish, because it is necessary to maintain the capacity of oxygen, carbon dioxide and hydrogen to avoid further reaction; There should be a gap between the plates to facilitate ventilation
