The air flow enters Mars 1200 Class II biological safety cabinet (BSC) work chamber via the front aperture and continues under the worktop, and up the rear plenum where 70% is recirculated through the main HEPA filters, providing the down flow and 30% exits out through the HEPA filter to exhaust. This working principle achieves efficiency at 99.995 % against 0.3 μm particles, ensuring a clean sterile work chamber environment.

• 11cm H-14 class HEPA filter, effectively filters 99.999% of 0.3um particles.

• More uniform deceleration airflow design, air flow speed is 0.28 ± 0.01m/s.

• 3 fans system, more efficient and energy-saving.

• Unique air laminar flow technology ensures unidirectional, vortex-free airflow.

• Low-flow air provides a more balanced operating environment.

• Microprocessor-controlled fan system for precise control of air flow rate.

• The 9° tilted front window design and the two side view windows make the operation more comfortable.

• The larger front window opening angle (20cm, 30cm) allows the use of the microscope inside the safety cabinet without interference from the front window.

• Lower air flow rate and larger filtration area to minimize working noise and create a quieter experimental environment.

• Adjustable illumination intensity (0-2000lux), shadow-free illumination to ensure a good view of the operation.

• All operations and maintenance can be performed fromthe front without moving the cabinet.
