No one chemical disinfectant is effective for all disinfection purposes. Choice of a chemical disinfectant depends on a number of factors such as the number and types of microbes to be destroyed (ex. bacteria, viruses, spores), toxicity, contact time required for disinfection, pH, temperature and presence of organic matter.

Surfactant 0.1 - 10 mmol/dm³, Polymer 8.3ppm, Temp. 25℃ ① Addition of PN-100 to surfactant solution results in a reduction of critical micelle concentration (CMC). It means that PN-100 has the potential for usage reduction of surfactant, because most performance (cleaning, penetration) of surfactant critically changes around CMC.

Which laundry enzymes work best? – Science in School

Mar 25, 2019·Each detergent should be tested at room temperature (around 20°C), and at 40°C and 70°C. In addition, carry out two more tests to act as controls: one using only water, and one using a solution of water mixed with non-biological detergent (i.e. no enzymes). In total, this part of the activity takes approximately 1 hour. Materials

Feb 01, 2006·(A) PIPLC assay. FRT cells were grown on 60 mm dishes and lysed in Triton X-114 buffer. Aqueous phases were accurately recuperated and TCA precipitated, while detergent phases were incubated for 1 hour at 37°C in the presence (+) or absence (–) of PIPLC (5U/sample). 2% Triton X-114 was added and the samples were incubated for 10 minutes on ice.

ADULTERATION AND DILUTION CHECKS

pH pH is a measure of the alkalinity of a specimen. Normal urine is fairly neutral and, depending on the person‟s diet, has a pH of around 7.0. The normal accepted range of testing is a pH between 4.5 and 8.0. A pH below this range is usually “flagged by” the analyzer as adulterated as it affects the absorption values generated in the ...
