Question

Which of the following would you use to disinfect the surface of your laboratory bench when you complete an experiment?

a.)Lysol

b.)An autoclave

c.)A phosphate-containing detergent

d.)Iodine

Answer 1

Lysol (Option A) is the most suitable choice for disinfecting a laboratory bench since it contains effective microbial growth controlling compounds and is meant for surface disinfection.

Step-by-step explanation:

To disinfect the surface of a laboratory bench after completing an experiment, the most suitable choice from the options provided would be Lysol (a). Lysol contains phenolic compounds which are effective in controlling microbial growth. Such phenolics have been used since Lister's time and have remained a common components in disinfectants. It's important to recognize that disinfection doesn't lead to sterilization, as disinfectants inactivate most microbes but may not eliminate tough endospores. Autoclaves (b) are used for sterilizing materials with heat and pressure, not for disinfecting surfaces. Phosphate-containing detergents (c) are cleaners but are not necessarily disinfectants. Iodine (d) can be used as an antiseptic for skin but is less commonly used for disinfecting surfaces due to potential staining and irritation.

Answer 2

The choice of disinfectant to use on the surface of a laboratory bench after completing an experiment depends on the specific requirements and protocols of the laboratory. However, out of the options provided, the most commonly used disinfectant for laboratory surfaces is typically a phosphate-containing detergent.

Option c.) A phosphate-containing detergent is often used for routine cleaning and disinfection of laboratory surfaces. These detergents have the ability to remove dirt, grime, and organic matter from the surface, while also providing a certain level of disinfection. They are effective against a wide range of microorganisms and can help maintain a clean and safe laboratory environment.

Lysol (option a.) is a brand of disinfectant that is commonly used in households, but it may not be the most suitable choice for laboratory bench disinfection, as it may not meet the specific requirements and standards of laboratory settings.

An autoclave (option b.) is a device used for sterilization rather than disinfection. It utilizes high-pressure steam and heat to kill microorganisms and is typically used for sterilizing laboratory equipment rather than surfaces.

Iodine (option d.) is an antiseptic that can be used for disinfection purposes, but it is not commonly used to disinfect laboratory surfaces due to potential staining and other limitations..
