Every particle matters. Why cleanroom laboratory chairs?

In controlled lab environments, even tiny particles pose a big risk. Cramer cleanroom chairs and stools are engineered to minimize particulate release, keeping contamination out and productivity up.

What makes a Cramer cleanroom chair:

  • Sit-stand functionality to support ergonomic movement
  • ISO 14644-certified for Class 3 to 5 environments
  • Low-shedding casters to reduce airborne particles
  • Sealed pneumatic cylinders and low-particle-emission polyurethane
  • Chemical-resistant surfaces built for daily disinfecting

Certified where it counts.

Cramer cleanroom chairs meet ISO 14644 standards for particle control—tested for low emissions, sealed for clean performance, and trusted in environments where even a speck can throw everything off.

Uncontaminated answers to cleanroom chair questions.

ISO classes, particle control, and what a seam can sabotage—it’s all here. No dust, no fluff.

Both materials perform the sameAll chairs in a cleanroom laboratory must be ISO rated

  • All chairs in a cleanroom laboratory must be ISO rated
  • All of our chairs meet the cleanroom classification standards. No matter how you spec any one of our chairs, they qualify / are covered under ISO ratings
  • We can reiterate this type of answer if it’s helpful: ISO classifications measure how many microscopic particles are floating around, and a lower class means stricter standards and a cleaner environment. in cleanroom settings

Anyone working where contamination—airborne or otherwise—could wreck the results. Pharma, biotech, semiconductors, diagnostics … basically, anywhere that can’t risk dust, gunk, or bacteria hiding where it shouldn’t.

Three and a half, if you count the stool (and we do).

  • Citrus – ISO Class 3
  • Helix – ISO Class 4
  • Fusion – ISO Class 5
  • Fusion Round Stool – ISO Class 5

Each one is tested, certified, and ready for cleanroom work, with or without a backrest.

Think of it like golf: the lower the number, the cleaner the room. ISO classifications measure how many microscopic particles are floating around, and a lower class means stricter standards and a cleaner environment.
