Many factors influence the effectiveness of the active ingredients in biocides. Some of them include:

Surface type
Contact time
Organic soil
Hardness of the water

The actives used against fungal spores will perform differently depending on the factors above. It is therefore necessary to perform in-house testing.

One piece of equipment many cleanroom managers have to consider is a clean bench. Depending on the purpose of the bench, more than one may be necessary. When it comes to clean benches, the options are numerous.

Clean benches and workstations generally use either HEPA or ULPA filtration systems. They provide workspaces for applications like conducting research or isolating a manufacturing process. They tend to come in tabletop, standup, or sitdown models. They come in a variety of materials, and vertical and horizontal flow combinations. Here are features of some of these benches.

Horizontal Laminar Flow – This is a general-purpose bench used for lab work, testing, inspection, manufacturing, and other operations. HEPA filter provides an ISO 5 working environment.
