Ultra-Clean Bench

The clean bench draws in air through a fan, which is filtered by a high-efficiency filter to create a vertical or horizontal laminar flow of clean air, blowing away particles in the work area. It is used to provide a local dust-free environment, prevent sample contamination, and is applied in operations such as microbial inoculation and cell culture.
Selection
When selecting a biosafety cabinet, consider the cleanliness level, airflow pattern, and compatibility with experiments. Ensure the biosafety level corresponds to the type of operations, the materials are corrosion-resistant and easy to clean, and the dimensions fit the available space and operational needs. Additionally, prioritize stable airflow with low noise levels, along with accessible filter replacement at a reasonable cost.

Their core components include force sensors, sample stages, and data processing systems.
What are the differences between horizontal airflow and vertical airflow in a clean bench?
Purification workbenches primarily employ two types of air supply methods: horizontal and vertical. In horizontal air supply, the airflow is parallel to the work surface, while in vertical air supply, the airflow moves from top to bottom, forming a laminar barrier. The selection should be based on a comprehensive consideration of experimental needs, sample characteristics, and safety requirements.
For electromagnetic vibration tables, whether to choose sweep frequency or fixed frequency testing standards for simulating transportation is crucial; do not make a random selection if you are unsure.
The electromagnetic vibration table is used to simulate transportation vibrations and test the durability of products and packaging. There are two types of tests: fixed-frequency and sweep-frequency. The selection should be based on the test objectives and relevant standards to avoid arbitrary choices. For new products, it is recommended to first conduct a sweep-frequency test to identify resonance points, followed by fixed-frequency tests as needed.
