A Passthrough for Cleanrooms is a First Line of Defense Against Contamination


Contamination is the enemy of anyone working in a laboratory or other type of clean room. Contaminationcan come for a variety of sources including the people who work there, poorly filtered air and form the equipment in the clean room. Controlling the possiblity is a key factor in ensuring that the desried outcomes are reached in the lab or for the processes going on in the clean room.

When a clean room environment is compromised by contamination. The experiements or processes occuring are no longer viable. Contamination can also put the clean room personnel in danger and create major added expenses.

These clean room contamination strategies fit into procedures and protoclols that assist clean room teams with getting acurate results while working in their clean room environments. With proper understanding they are easy to implement and enforce by using specialized tools that assist greatly with avoiding contamination and by utilizing standairzed practices for how to operate while entering leaving and operating within the celan room.

There is no strategy for preventing contamination 100% but as mentioned, but when proper protocols are followed, the likelihood of there being contamination is moved down next to zero.

One key tool in the fight against contamination is a passthrough for cleanrooms:

Pass Throughs

Passthroughs are used in all types of laboratories and other rooms where the environment is controlled and materials are transferred in and out. Essentially these materials will need to be disinfected or otherwise cleaned and this is where passthroughs are critical.

Passthroughs have become a primary tool in clean rooms. They are used for the controlled moving of materials in and out. Clean rooms use pass through chambers, also called passthroughs, pass-through air locks, chambers or transfer hatches because they standardize and simplify contamination-free transfer of materials in and out of a controlled environment.

How they operate varies in complexity but there is a basic set up. A pass through is typically built into a wall in the room or may be an entire room itself. It will always contain two sets of doors or hatches on either end of a chamber that cannot be opened simultaneously. A material, substance or even person enters or is placed at one end of the pass through chamber that end is sealed creating a totally sealed environment. The article or person within the pass through is then disinfected. When this is complete the hatch or door at the other end of the pass through will be able to be opened. The result is that no contaminated materials will enter the clean room. Pass through can work in both directions in the even that there is potentially hazardous materials in the clean room and there is a concern they might be transported outside.

Passthroughs are serviced regularly to ensure that they are working properly. Their proper use is a front line defense against contamination which can be costly and a threat to the health of workers.
