Verified step by step guidance

1. Understand the purpose of a three compartment sink in microbiological cleaning: it is designed to ensure thorough washing, rinsing, and sanitizing of lab equipment or utensils to prevent contamination.
2. Identify the sequence of steps in the cleaning process: first, washing to remove visible dirt and organic material; second, rinsing to remove soap and residues; third, sanitizing to kill microorganisms.
3. Recognize that the first compartment is used for washing, which requires filling it with hot soapy water to effectively break down and remove contaminants.
4. The second compartment is then filled with clean water for rinsing the items after washing, ensuring no soap remains.
5. Finally, the third compartment is filled with a sanitizer solution to disinfect the items before drying them with a clean towel.
