But this high price is beneficial for the non-contaminated transfer of materials between two areas with different levels of cleanliness.

But always consult your supplier to discover whether your requirements will be fulfilled by the Static or the Dynamic Pass Box.

What are the Transfer Protocols of a Static and Dynamic Pass Box?

The maintenance and management of the Static and Dynamic Pass Box are dependent on the management of the clean area where it is installed, according to the cleanliness level in it.

If a pass box is installed in the filling and code spraying room, manage your pass box according to the cleanliness level of the filing room.

When you are finished operating your equipment, always sterilize the internal surfaces, working area, and everything for 30 minutes using the UV sterilization lamp.

Always use specially designed and highly effective pass boxes for transporting sensitive materials to the contaminated areas. The same rule implies transporting the waste content.

It is strictly not allowed to simultaneously open both the doors of the pass box when entering the stainless steel pass box, as this can result in higher chances of contamination.

When you have put the material to be transferred from one door, close this door first and then open the door at the other end to take the material out of the pass box.

This way, there will be less access for the contaminants to enter this controlled space.

When you take out the materials from this space, place them into the temporary receiving station.

For taking them out, reverse the procedure given for putting them into the pass box. For transferring these materials to the external packaging room, use the logistics channel.

It is crucial to clean the windows and surfaces of the temporary storage room and the packaging room after materials are moved through these rooms when placed into or taken out from the pass box.

During the cleaning procedure, make sure that all the doors of the Static and Dynamic Pass Box are closed so that contaminants don’t enter this space.

What are the Quality Assurance Instructions of a Static and Dynamic Pass Box?

In the pharmaceutical industry, qualification of pass boxes is a quality control process that entails recorded verification of the equipment’s consistency in giving an efficient performance for the required task.

Although no standard exists to define the technique for certifying a pass box.

The rules outlined in ISO 14644 or other globally-recognized standards can be applied because they have similar functioning as that of a unidirectional airflow device.

So, you have to conduct an airflow velocity test for determining the average velocity of the airflow velocity through the box.

For accuracy, the quantifying range should be a transverse area of that face of the filter that forms a 90 degrees angle to the airflow plane.

When considering a hot wire anemometer or any other one-point measuring device, split the filter face into equal parts.

Each section should have a surface area of no more than 0.09 meters square.

On the other hand, when considering a Vel-Grid or any other multi-point device the section size should not exceed 0.37 meters square.

Record the velocity of the airflow at every grid point, maintaining a distance of 150 mm from the face of the filter or the same distance from the grille present over the filter.

0.45 m/s or plus or minus 20% should be the average velocity of the airflow.

What is the ISO Standard Classification of Static and Dynamic Pass Box?

Different types of the Static and Dynamic Pass Box follow different levels of ISO standards. As per these standards:

• The ISO 7 clean rooms are most likely to use Static Pass Boxes.

• The ISO 4 clean rooms possess features compatible with the active pas boxes.

This test is done to test the functionality of the pass box, which can help you in transferring materials from less clean to more clean environments, in a non-contaminated way.

Using this test, you may get a better understanding of which equipment will be suitable for which application.

Lab Operator Testing Static Pass Box

Which Recovery Tests are Used for Static and Dynamic Pass Box?

A recovery test helps in figuring out how efficiently will a pass box get back to its actual cleanliness level once it is exhibited in a contaminated environment.

There are two strategies available for this test. The standard ISO 14644-3 covers the first strategy, which tells to sample at the middle zone of the work surface.

This process should be started with determining the particle count first for setting up the present particle concentration level.

Then create a particle challenge, which is usually an aerosol to 100 times more than the required level of cleanliness.

Keep track of the start time and start concentration measurements as the challenge activates.

Every minute, for six seconds, you should record the challenge concentration till the pass box gets back to its actual particulate concentration.

The second strategy supposes a pure air supply with a zero concentration, allowing for the calculation of recovery time using the standard equation.

The standard equation helps in finding the relationship between the recovery period and the air change rate.

Conclusion.

Installing a Static and Dynamic Pass Box in your sterile room helps in maintaining sanitation.

These boxes are highly efficient and prevent the direct airflow between two areas of the same as well as different sanitation levels.

To get the best results make sure to use it correctly following all the standard operational protocols.

Always take care of the regular cleaning and maintenance of your Static and Dynamic Pass Box to improve its shelf life, durability, and reliability.
