What is the purpose of pre-rinsing equipment before use?

The purpose of pre-rinsing equipment before use is primarily to remove any urine precipitates that may have formed and resulted in opaque scale. This step is crucial in ensuring that any residues or contaminants are eliminated before the equipment comes into contact with the animals or materials being used in the laboratory. Pre-rinsing can help maintain a clean environment, which is essential for the health and well-being of laboratory animals as well as the integrity of experimental results.

Thorough cleaning and pre-rinsing reduce the risk of cross-contamination and help ensure that the equipment is free from chemical residues, organic materials, or other contaminants that might interfere with experimental procedures or impact animal welfare. By addressing these issues before utilizing the equipment, laboratory personnel can uphold best practices in hygiene and protocol adherence.
