2021/07/10 · Introduction Community-acquired pneumonia (CAP) is one of the most common serious infective diseases, accounting for nearly 1% of all medical admissions. 1 The incidence of CAP in the UK increased by 34% between 1997 and 2005, 1 and the rates of serious complications of CAP, such as admissions to intensive care and complicated parapneumonic effusions (CPE), are also on the
Cap both vials and shake vigorously (more than 30 seconds). Place the vials in the COD Reactor. Heat for 30 minutes. Note: The persulfate reagent may not dissolve completely after mixing. Note
COD digestion reagent vials, multiply the result by 10. For the most accurate results with samples near 1500 or 15,000 mg/L COD, repeat the analysis with a diluted sample. Blanks for colorimetric determination The blank vial can
Vials labeled by the manufacturer as “single dose” or “single use” should only be used for a single patient. These medications typically lack antimicrobial preservatives and can become contaminated and serve as a source of infection

The DR2000 should be pre-programmed with the COD method. To use the COD vials with this instrument, you will need to use the COD Vial Adapter. Based off page 23 of the manual, it looks like the pre-programmed COD methods are Method # 430 (COD limit 200 ppm) and Method # 435 (COD limit 2000 ppm). For the B1015 COD vials
2013/05/01 · Despite these limitations, this study offered evidence that the flip-top cap of medication vials does serve as adequate barrier protection to aerosolized microbial contamination. The study also demonstrated the access diaphragm’s ability to support microbial contaminants during routine handling.
