Description

The biological safety cabinet, models YR06543 // YR06547, is a state-of-the-art solution designed to protect personnel, products, and the environment thanks to its negative pressure system that prevents leaks. It operates on a principle of 70% internal circulation and 30% external discharge. The structure is made of high-quality cold-rolled steel and the work surface is made of corrosion-resistant physicochemical plate. Precision CNC laser cutting and electrostatic epoxy resin spray surface treatment ensure durability. The system integrates intelligent control with an LCD touch screen that allows intuitive understanding of the operating status. The cabinets comply with the international standard ISO14644.1 Class 5 (equivalent to the US Federal Standard 209E, Class 100).

Motor: adopts the German EBM motor with high airflow and low energy consumption, optimized to reduce turbulence concentration and ensure airflow uniformity.

Filtration: equipped with high-efficiency external HEPA filters and very high-efficiency downward ULPA 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 accuracy of the downward airflow control?

The accuracy of the downward airflow control is 0.015 m/s, which ensures uniformity and stability of the flow to maintain sterility in 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 downward ULPA/HEPA filters, ensuring up to 99.999% efficiency.
Superior safety (negative pressure): the negative pressure design prevents leaks, thus protecting the operator and the environment.

Optimized design: reasonable air duct and optimized negative pressure box for flow uniformity.
High-performance German motor: uses a low-power, 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 and 30°C with relative humidity below 70%.
Shipping weight: the shipping weight is considerable, ranging from 138 kg to 198 kg (depending on size), which can complicate transport and installation.
Flow limitations: although it is a recirculation system (70% internal), the 30% external discharge requires an exhaust ventilation system.

Product use in the field

The Class II Type A2 biological safety 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, and biotechnology and pharmaceutical research centers, where protection of the product, personnel, and environment is essential. Its vibration control capability (half-wave: 3 μm) and stable airflow are essential for delicate experiments.

Recommendations

To ensure longevity and maximum safety:

Perform regular maintenance on the filters and check the calibration of the imported sensor.
Check that the working environment meets the temperature (10-30 °C) and humidity (below 70%) requirements.
Periodically check the inlet flow velocity (average of 0.53 m/s to 0.56 m/s) and downward airflow velocity (average of 0.35 m/s) to ensure the effectiveness of negative pressure protection.
Use heavy-duty casters (heavy-duty mobile wheels) for initial positioning and ensure that it is stable before use.
