Function of the Clean Bench:
The clean bench has a specific function in providing a controlled and sterile working environment. Here are some key points about the function of a clean bench:

Contamination Control: The main function of the clean bench is to control and minimize contamination in the working area. It achieves this by using high-efficiency particulate air (HEPA) filters that remove airborne particles, including dust, microorganisms, and other contaminants. The filtered air is then directed in a laminar flow over the workspace, creating a clean and controlled environment.

Sterile Workspace: The clean bench creates a sterile workspace by eliminating and preventing the entry of contaminants. This is particularly important in fields such as microbiology, pharmaceuticals, or biotechnology, where maintaining a sterile environment is crucial for accurate results and the integrity of samples or experiments. The clean bench helps protect sensitive materials and samples from external contamination.

Sample Protection: A clean bench provides a barrier between the working area and the surrounding environment, safeguarding samples from contamination. The laminar flow of filtered air helps prevent particles or microorganisms from settling on the samples, ensuring their purity and reliability. This is vital for tasks that require aseptic conditions, such as cell culture, DNA analysis, or preparation of sterile solutions.

Operator Safety: In addition to protecting samples, the clean bench also offers a degree of safety for the operator. The laminar flow of filtered air helps create a physical barrier between the operator and potentially harmful substances, reducing the risk of exposure to hazardous materials or biohazards. This helps maintain a safe working environment, especially in laboratories or cleanroom settings.
