EC Series Class II B2 Biological Safety Cabinet EB2-4F (CAT#: STEM-OEM-0038-ZJF)

A biosafety cabinet is a box-type negative pressure air purification unit designed to effectively contain biological aerosols during laboratory operations. As a primary safety measure in biosafety level 1 containment, it is widely used in microbiology, genetic engineering, biopharmaceutical manufacturing, education, and clinical research environments.

7-inch touch color display supports touch operation and provides real-time, clear, and dynamic display of cabinet values; includes appointment timing functionality.
Power-on password can be set to prevent unauthorized operation by unrelated personnel.
Wind speed automatically adjusts to maintain consistent airflow.
Power-off memory function restores the previous working state after power is resumed, with visual prompts and alarms.
Integrated operation area design allows easy disassembly and cleaning.
Wind speed sensor in the working area enables real-time detection of airflow conditions.
Supports simultaneous manual and electric operation; the front window can be closed manually by pulling down the glass door during a power outage.
Cabinet and base are separate; adjustable base height can be customized.
Interlocking function ensures safe coordination between UV lamp and front window, UV lamp and fan, LED lamp, and fan and front window.
Appointment timing function allows scheduled startup and shutdown of the cabinet and timed operation of UV lamp, fan, and sockets.
Front window closure activates a double-trigger signal, enabling proper activation of the UV sterilization and disinfection function.
Negative pressure air duct includes a filtering structure to prevent foreign matter such as paper scraps from entering the fan system.
Front window glass features a one-key lift function for convenient operation.
Cabinet features a 10° forward tilt design, improving ergonomics, expanding viewing angle, and enhancing user comfort and operability.
