How does the weighing cover prevent cross-contamination?

The weighing cover provides a vertical unidirectional airflow where part of the clean air circulates in the workspace and part is discharged to nearby areas. This creates a negative pressure in the working area, effectively preventing cross-contamination.

What standards does the filtration system meet?

It uses the latest tank-type high-efficiency filter which is more sealed and meets the latest GMP requirements. The cleanliness reaches ISO Level 5, which is better than grade 209E 100.

Introduction Detail

Weighing cover provides a vertical unidirectional airflow. Part of the clean air circulates in the workspace, while partial discharge occurs to nearby areas. This makes the working area negative pressure, which effectively prevents cross-contamination and ensures a high cleanliness environment in the work area.

Detailed FAQ

How is cross-contamination prevented during the weighing process?

The weighing cover maintains a negative pressure environment by discharging part of the air to nearby areas. This pressure gradient ensures that particles generated during weighing are contained and filtered, protecting the external environment.

What makes your filtration system different for GMP compliance?

We utilize the latest tank-type high-efficiency filters. Compared to traditional filters, these provide a superior seal, which is critical for meeting the strict requirements of the latest GMP pharmaceutical standards.

Is the air velocity consistent throughout the workspace?

Yes. Our system uses a wind speed detection automatic frequency conversion system combined with uniform flow film technology. This keeps the vertical airflow in an ideal constant state across the entire ISO Level 5 work area.
