• Air Intake: Ambient air is drawn into the cabinet through an intake grille.

• Filtration: The air passes through a HEPA filter, removing 99.97% of particles ≥0.3 microns.

• Laminar Airflow: Filtered air is directed vertically downward in a smooth, uninterrupted flow.

• Clean Workspace: The downward airflow creates a contamination-free zone, protecting the work area and materials.

• User Safety: The design minimizes exposure to airborne contaminants, enhancing operator safety.

• Maintained Pressure: The cabinet maintains a slight negative pressure to prevent external contaminants from entering.

• Consistent Environment: Provides a stable and sterile environment for sensitive applications.

• Stainless Steel Orifice Tabletop

• ULPA Ultra GX Filter

• UV Germicidal Lamps

• De-static equipment

• Support Stand with Caster Wheels
  

1. What is a medical clean bench?

A medical clean bench is a workstation designed to provide a sterile environment for various laboratory tasks. It utilizes HEPA-filtered air to create a contamination-free workspace, ensuring that sensitive procedures are performed in a clean environment.

2. How does a vertical laminar flow cabinet work?

A vertical laminar flow cabinet works by drawing air through a HEPA filter and then pushing it downwards in a vertical direction over the work surface. This creates a continuous flow of clean air, which helps to protect the work area from contaminants.

3. What are the benefits of a vertical laminar flow cabinet?

Vertical laminar flow cabinets offer several benefits:

• Enhanced protection from contaminants

• Suitable for a wide range of applications

• Ergonomic design

These cabinets provide a clean airflow pattern that reduces the risk of cross-contamination, making them ideal for sensitive laboratory tasks.

4. How to maintain a medical clean bench?

Maintaining a medical clean bench involves several key steps:

• Regularly clean the surfaces with appropriate disinfectants.

• Replace HEPA filters as per the manufacturer's guidelines.

• Perform routine airflow checks to ensure optimal performance.

Proper maintenance ensures the clean bench continues to provide a sterile environment for laboratory work.

5. What is the difference between a clean bench and a biosafety cabinet?

The primary difference between a clean bench and a biosafety cabinet lies in their function and airflow patterns. A clean bench provides a sterile work environment by directing HEPA-filtered air over the workspace. In contrast, a biosafety cabinet protects both the user and the environment from hazardous materials by containing and filtering contaminated air.

6. How often should HEPA filters be replaced in a vertical laminar flow cabinet?

HEPA filters in a vertical laminar flow cabinet should generally be replaced every 1-3 years, depending on the frequency of use and the level of contaminants in the work environment. Regular inspections and performance tests can help determine the appropriate replacement schedule.

7. Can a vertical laminar flow cabinet be used for tissue culture?

Yes, a vertical laminar flow cabinet can be used for tissue culture. The sterile environment provided by the HEPA-filtered airflow is ideal for preventing contamination during tissue culture procedures.

8. What is the airflow pattern in a vertical laminar flow cabinet?

In a vertical laminar flow cabinet, the airflow pattern is directed vertically from the top of the cabinet downwards over the work surface. This vertical flow helps to push contaminants away from the work area and towards the exhaust filters, maintaining a clean environment.

9. How to properly clean a medical clean bench?

To properly clean a medical clean bench:

• Turn off the airflow and unplug the unit.

• Use a lint-free cloth and a suitable disinfectant to wipe down all surfaces.

• Pay special attention to corners and hard-to-reach areas.

Allow the surfaces to dry completely before turning the unit back on to ensure a sterile environment.

10. What are the best brands for medical clean benches?

The best brands for medical clean benches include:

• Deiiang

• Esco

• Labconco

These brands are known for their high-quality construction, reliable performance, and adherence to industry standards.

11. How to install a vertical laminar flow cabinet?

Installing a vertical laminar flow cabinet involves several steps:

• Choose a suitable location with adequate space and proper ventilation.

• Assemble the cabinet according to the manufacturer’s instructions.

• Connect the unit to a power source and ensure it is level.

Perform initial performance tests to confirm proper airflow and filter integrity before use.

12. What is the purpose of a medical clean bench?

The purpose of a medical clean bench is to provide a sterile environment for various laboratory procedures. It helps to protect sensitive samples and processes from contamination by using HEPA-filtered air to maintain a clean workspace.

13. How to measure airflow in a vertical laminar flow cabinet?

Airflow in a vertical laminar flow cabinet can be measured using an anemometer. Place the anemometer at various points on the work surface to ensure consistent airflow. The readings should match the manufacturer’s specifications for optimal performance.

14. What is the difference between horizontal and vertical laminar flow cabinets?

The main difference between horizontal and vertical laminar flow cabinets is the direction of airflow. Horizontal laminar flow cabinets direct air horizontally across the work surface, while vertical laminar flow cabinets direct air downwards from above. Vertical cabinets are often preferred for tasks requiring sterility, as they reduce the risk of cross-contamination.

15. How much does a vertical laminar flow cabinet cost?

The cost of a vertical laminar flow cabinet can vary widely based on size, features, and brand. Generally, prices range from $2,000 to $10,000. High-end models with additional features may cost even more.

16. How to troubleshoot a medical clean bench?

To troubleshoot a medical clean bench, follow these steps:

• Check the power supply and ensure the unit is plugged in.

• Inspect the HEPA filters for clogs or damage.

• Verify the airflow with an anemometer.

If issues persist, consult the manufacturer’s manual or contact technical support for further assistance.
