The main difference between cleanroom classes is the cleanliness level of the air within the controlled environment.

In the United States, cleanroom operators follow ISO standards: ISO 1 being the cleanest, and ISO 9 being the least clean.

Why are some cleanrooms labelled Class 10,000?

ISO classes may be labeled as Class 100,000; Class 10,000; Class 1,000; and so on until Class 1.

But this is an outdated standard done away with 2001 and replaced with ISO-14644-1.

You can see the Federal Standard 209 (FS 209E) equivalent standards here:

  • ISO 8 – Class 100,000
  • ISO 7 – Class 10,000
  • ISO 6 – Class 1,000
  • ISO 5 – Class 100
  • ISO 4 – Class 10
  • ISO 3 – Class 1

Cleanroom Gloves - Manufacturing Process

Gloves manufactured for cleanrooms are not manufactured the same as general purpose nitrile or latex gloves

You especially do not want to use food service gloves in your cleanroom. But why can’t you? 

It might seem obvious, but shouldn’t a high quality nitrile glove be enough? 

Why can’t you use any disposable glove in cleanrooms?

The chlorination manufacturing process of cleanroom gloves reduces the natural rubber protein levels as well as particulate and ionic residuals. 

Chlorination also reduces tack levels by washing the gloves in a solution of chlorine gas and water. Less tack allows for easier glove donning off and on!

Post chlorination processing and testing is very important to the manufacturing process of Cleanroom Gloves.

After chlorination the gloves are processed through multiple deionized water rinse cycles to further reduce residual contaminants. In this process, excess particulates, extractable ions, and nonvolatile residues are removed.

The gloves are then dried in HEPA filtered dryers prior to packaging. This part of the process is undertaken in a cleanroom environment.

Sterile gloves undergo further processing.

What does the cleanroom glove manufacturing process look like?

As you can see, the manufacturing process of cleanroom nitrile gloves is swift, precise, and checked to the highest standards. The enemy of clean rooms is particulates that cause contamination and can damage the sensitive products being produced.

If you’re operating a critical environment make sure to use material manufactured for cleanrooms. Whether it is gloves, documentation, adhesive mats, mops, disposable apparel or other supplies, you can find all the cleanroom supplies you need at Harmony Lab & Safety Supplies.
