Biological safety cabinet YR06538 // YR06542

The biological safety cabinet, models YR06538 and YR06542, is a cutting-edge solution designed to protect personnel, products, and the environment, thanks to its negative pressure system that prevents leaks. It uses a principle of 70% internal circulation and 30% external discharge. The structure is constructed of high-quality cold-rolled steel and the work surface is made of corrosion-resistant physical-chemical plate. CNC laser precision cutting and electrostatic epoxy resin spray surface treatment ensure durability. The system incorporates intelligent control with an LCD touch panel that allows intuitive understanding of the operating status. The cabinets comply with the international standard ISO14644.1 Class 5 (equivalent to US Federal 209E, Class 100). Motor: Adopts the German EBM motor with high air volume and low energy consumption, optimized to reduce turbulence concentration and ensure airflow uniformity. Filtration: Equipped with external HEPA high-efficiency filters and downward ULPA ultra-high-efficiency filters.

Frequently Asked Questions

What is the difference between ULPA and HEPA filters? The G series uses ultra-high efficiency ULPA filters (99.999% efficiency), while the D series uses high efficiency HEPA filters (99.995% efficiency). Both are excellent, but ULPA offers a slightly higher level of purity. What is the precision of downward airflow control? The precision of downward airflow control is 0.015 m/s, which ensures flow uniformity and stability to maintain sterility within the work area. What sizes are available? What level of cleanliness does the cabinet guarantee? The cabinet guarantees Level 5 of the international standard ISO14644.1 (Class 100 US Federal 209E), a strict requirement for sensitive environments.

Advantages and Disadvantages

Advantages: Double Filtration: Uses external HEPA filters and ULPA/HEPA downflow filters, guaranteeing up to 99.999% efficiency. Superior Safety (Negative Pressure): The negative pressure design prevents leaks, protecting the operator and the environment. Optimized Design: Reasonable air duct and optimized negative pressure box for flow uniformity. High-Performance German Motor: Uses low-consumption, high-air-volume EBM motor. Durable Construction: Corrosion-resistant cold-rolled steel and epoxy resin surface treatment. Disadvantages: Environmental Requirements: The working environment must be maintained between 10-30°C and relative humidity below 70%. Shipping Weight: The shipping weight is considerable, ranging from 138 kg to 198 kg (depending on size), which can complicate transportation and installation. Flow Limitations: Although it is recirculating (70% internal), the 30% external discharge requires consideration of an exhaust ventilation system.

Product Use in the Field

The Class II Type A2 Biosafety Cabinet is indispensable for handling low to moderate risk biological agents, such as viruses, bacteria, and cell cultures, which require biosafety. It is the standard choice in microbiology laboratories, hospitals, biotechnology and pharmaceutical research centers where product, personnel, and environmental protection is critical. Its vibration control capability (half-peak: 3μm) and stable airflow are essential for sensitive experiments.

Recommendations

To ensure longevity and maximum safety: Perform regular maintenance on the filters and check the calibration of the imported sensor. Confirm that the working environment meets the temperature (10-30°C) and humidity (below 70%) requirements. Periodically check the inlet flow velocity (average 0.53m/s to 0.56m/s) and downward airflow velocity (average 0.35m/s) to ensure that negative pressure protection remains effective. Use heavy-duty mobile casters for initial positioning and ensure stability before operation.
