OSMT (Ontario Society of Medical Technologists) Practice Exam

When dissolving a Nucleopore filter, a common dissolving agent is:

1. a. saline

2. b. alcohol

3. c. Isotones

4. d. none of the above

The correct answer is: d. none of the above

The appropriate dissolving agent for a Nucleopore filter is often a specific solvent designed to break down the materials used in the filter's construction. In practice, common solvents include various types of alcohol, such as ethanol or isopropanol, because these can effectively dissolve the materials without introducing contamination. In this context, while saline and isotones may be useful in various laboratory applications, they do not serve as dissolving agents for a Nucleopore filter. Saline is typically used for washing or suspending cells, and isotonic solutions are used to maintain cellular integrity. None of these substances would effectively dissolve the filter material itself. Therefore, the choice of a common dissolving agent for a Nucleopore filter aligns with the use of alcohol. Thus, that would be the correct answer in this scenario.
