Cleanroom Gloves: Nitrile, Latex or Neoprene?
Cleanroom gloves protect both product and process from particles, ions and skin contamination. This guide compares nitrile, latex and neoprene and shows how to choose by cleanroom class per ISO 14644-1, particle count, fingertip texture and chemical resistance.
View cleanroom glovesNitrile, latex or neoprene - which material?
The material determines chemical resistance, tactility and allergy risk. Nitrile is the cleanroom standard because it is latex-free, resists oils and many solvents and offers high puncture resistance. Latex delivers the best tactile feel and elasticity but carries a protein allergy risk. Neoprene (chloroprene) sits in between and excels against aggressive chemicals and acids.
For electronics and semiconductor work nitrile is preferred because it can be finished low in particles and amines and free of silicone. In pharma and life-science production nitrile or neoprene are common to eliminate latex proteins entirely.
How does the glove match the cleanroom class?
The cleanroom class per ISO 14644‑1 sets how low in particles the glove must be. The higher the class (the smaller the ISO number), the stricter the requirement on particle count, finishing and packaging. Cleanroom gloves are therefore washed, rinsed in DI water and double-bagged in the cleanroom, sterile or non-sterile.
- ISO 5 to ISO 7: washed, low-particle nitrile gloves, non-sterile, usually ambidextrous.
- ISO 3 to ISO 4: class-certified gloves with documented particle and ion analysis (LPC, extractable ions).
- Aseptic processes: sterile gloves (gamma-irradiated), individually packed with size marking.
- ESD-sensitive areas: combine with dissipative cleanroom gloves for the EPA.
Fingertip texture, length and fit
Fingertip texture drives grip security on small components. A micro-rough or textured surface improves grip on wet and oily parts, while smooth finishes offer maximum sensitivity. Wall thickness, cuff length and fit complete the selection.
- Powder-free and low-sulphur to avoid outgassing and residues.
- Ambidextrous saves stock, anatomically shaped raises comfort.
- Cuff long enough to overlap the cleanroom suit so no skin is left exposed.
- Sizes S to XL kept neatly sorted so fit is correct and no fold contamination forms.
Frequently asked questions
Nitrile or latex in the cleanroom?
Nitrile is the standard because it is latex-free, oil and chemical resistant and puncture proof. Latex gives a better tactile feel but carries a protein allergy risk and weaker oil resistance.
What does the cleanroom class mean for gloves?
Per ISO 14644‑1 it sets how low in particles the glove must be. For ISO 3 to 5 you need washed, DI-rinsed gloves with a documented LPC and ion value.
Why are powder-free gloves important?
Powder releases particles and can contaminate products and surfaces. Cleanroom gloves are therefore powder-free, washed and low in sulphur.
When should you use sterile gloves?
For aseptic processes in class ISO 5 or better. Sterile gloves are gamma-irradiated, individually packed and marked with size.
