Biological Safety Cabinet ClassII Type B2

Product Description

YAKOS 40 Years of Manufacturing Experience
SAFZONE The Class II B2 biosafety cabinet is a high-performance biological safety device designed to protect operators, the environment, and samples, particularly when handling high-risk biological materials. This type of biosafety cabinet operates with 100% exhaust air, meaning no air is recirculated within the cabinet, ensuring that contaminated air is safely expelled from the laboratory.

Product Details

Specification

All air is filtered through HEPA filters and completely vented outside the laboratory, preventing recirculation. Vertical laminar airflow: Ensures a stable, unidirectional airflow to minimize cross-contamination.

Negative pressure design: Prevents hazardous air from escaping into the laboratory environment.

Suitable for handling toxic chemicals and volatile substances: Since there is no recirculated air, it is safe for operations involving both biological agents and chemical vapors.

The Class II B2 biosafety cabinet is essential in high-risk biological research and medical laboratories, with key applications including:

Microbiology and biomedical research:Used for handling Biosafety Level 2 (BSL-2) or Level 3 (BSL-3) pathogens, such as Mycobacterium tuberculosis or HIV.
Pharmaceutical development and cell culture:Ensures sterile conditions for cell culture processes while protecting operators from exposure to hazardous drugs.
Forensic and clinical diagnostic laboratories:Enables the safe handling of patient samples to prevent potential pathogen exposure.
Genetic engineering and biotechnology:Suitable for gene-editing technologies (e.g., CRISPR-Cas9) and virus vector research, ensuring biosafety and environmental protection.Because the Class II B2 biosafety cabinet offers the highest level of protection, it is particularly recommended for laboratories handling hazardous chemicals and high-risk pathogens. Proper installation, maintenance, and operation of these cabinets are crucial for ensuring laboratory safety and research integrity.

CONTROL SYSTEM SELECTION
Modular electronic components and neat wiring layout applied on SAFZONE^® Biosafety Cabinets to simplify the maintenance work. Electronic parts are easily accessible and easy to reach for the operator from the drop down control panel. Control systems and pipelines completely isolated from contaminated areas for convenient and safe maintenance.
7 Inch HMI Touch Screen

Advanced Human Machine Interface (HMI) Touch Screen mounted on SAFZONE^® BSCs to

provide user with a better graphic view for easy operation and function settings and continuous displays the cabinet’s performance.
♦ High resolution LCD display visualizes operating, monitoring and efficient control in real time.
♦ The large 7 inch full color touch screen enables intuitive parameter entry and displays variable data,
including trend graphs and alarm elements.
♦ User-friendly visual icons quickly creates users an “easy-to-navigate” to make operation more efficient.
♦ Display real time clock and date, inflow, downflow, negative plenum pressure, HEPA filter running hrs,
UV lamp running hrs at the front page.
♦ Main functions include:

– Automatic Pre-purge / Post-purge
– Built-in timer for counting up and down, UV light
– Safety interlock for window and UV light to protect the operator from UV irradiation
– Audible and visual text alarms for the following abnormal situations:
■ High / Low inflow velocity
■ High / Low downflow velocity
■ Wrong window operation height
■ High negative plenum pressure
■ Usage time of HEPA filter exceeds the setting hour HEPA
■ Usage time of UV lamp exceeds the setting hour UV
– Operation records including Inflow, Downflow and Pressure
– Multi-language display settings
– Two kind of unit display settings for air velocity and pressure

Membrane Switch Control Panel with Pressure Gauge

Membrane Switches are easy to use. Built-in UV light timer for 0~99 minutes / hours and negative plenum pressure gauge.
Safety interlock device controls blower, fluorescent light and UV light on/off by window sash open and closed.

WINDOW ALARM	When the window is not at the operation height, it will release an audible and visual alarm automatically.
MUTE SWITCH	When the alarm is activated, it can be muted temporarily while the alarm light continues to flash. If the abnormal situation has not been settled, the cabinet alarm will be activated again within a set time (5 minutes) to alert the operator.
SAFETY INTERLOCK	When the window is opened, the blower and fluorescent light will be activated automatically and the UV light will be switched off. When the window is fully closed, the UV light will be re-activated automatically. The blower and fluorescent light will be switched off.
UV LIGHT TIMER	Built-in UV light timer for 0~99 minutes / hrs.
PRESSURE GAUGE	Displays the negative plenum pressure of the cabinet in the unit of mm Aq.
