SUS304 Laminar Flow Hood with high-efficiency 0.3um particulate air (HEPA) filter

Clean Bench (Laminar Flow Hood)‌

A clean bench is a device designed to provide a local dust-free and sterile operating environment, primarily used to protect experimental samples or products from external contamination. It works by drawing air in through a pre-filter with a fan, then expelling it after passing through a high-efficiency particulate air (HEPA) filter, creating a vertical or horizontal laminar airflow that achieves a Class 100 cleanliness level in the operating area.

‌Key Features‌

• ‌Purpose‌: Protects samples or products from dust or bacterial contamination in the surrounding environment.
• ‌Safety‌: Operates under positive pressure; the laminar airflow may direct air containing microbial materials toward the operator, posing safety risks.
• ‌Applications‌: Suitable for experiments requiring high cleanliness but no biological hazards, such as cell culture or precision instrument operation.

‌Difference from Biosafety Cabinets‌
Biosafety cabinets are negative-pressure devices that protect the operator, the experimental environment, and the sample, making them suitable for handling infectious materials. In contrast, clean benches only protect the sample and should not be confused with biosafety cabinets.

‌Usage Precautions‌

1. ‌Before Use‌: Wipe the work surface with 75% alcohol and sterilize with UV light for 30 minutes.
2. ‌During Use‌: Avoid rapid hand movements or placing vibrating equipment (e.g., centrifuges) to prevent airflow disruption.
3. ‌Prohibited Actions‌: Do not use for microbiological experiments or turn on UV lights during operation.
