Question 1

What cleanroom class are TuoFu cleanroom chairs suitable for?

Accepted Answer

TuoFu cleanroom chairs are designed for ISO Class 3–8 environments (equivalent to US Federal Standard 209E Class 1–100,000). The specific suitability depends on the model and configuration. Our sealed PU vinyl chairs with stainless steel frames are suitable for ISO Class 5 and above. For ISO Class 3–4 environments, we recommend our fully welded stainless steel models with autoclave capability.

Question 2

What is GMP cleanroom seating and why does it matter?

Accepted Answer

GMP (Good Manufacturing Practice) cleanroom seating refers to chairs designed to comply with pharmaceutical manufacturing regulations, particularly EU GMP Annex 1 for sterile product manufacturing. Key requirements include: smooth, non-porous surfaces that can be validated for cleaning, no particle shedding, chemical resistance to disinfectants (IPA, hydrogen peroxide, etc.), and materials compatible with cleanroom cleaning protocols. Non-compliant seating can introduce contamination risks that compromise product quality and regulatory compliance.

Question 3

Can cleanroom chairs also have ESD properties?

Accepted Answer

Yes. TuoFu offers cleanroom chairs with integrated ESD properties, combining ISO Class 5–8 cleanroom compatibility with IEC 61340-5-1 ESD compliance. The ESD version uses conductive PU vinyl upholstery (surface resistance 10⁶–10⁹ Ω) and an ESD-conductive base and casters. This combination is particularly important for semiconductor fabrication and electronics cleanrooms where both particle control and ESD protection are required.

Question 4

What cleaning agents are compatible with TuoFu cleanroom chairs?

Accepted Answer

TuoFu cleanroom chair upholstery is compatible with common pharmaceutical cleanroom disinfectants including 70% IPA (isopropyl alcohol), hydrogen peroxide (H₂O₂) solutions, quaternary ammonium compounds, and dilute bleach solutions. Stainless steel frame models are compatible with stronger disinfectants and can be wiped down with all standard cleanroom cleaning agents. We recommend testing with your specific cleaning protocol before full deployment.

Question 5

Are pharmaceutical lab chairs available with custom colors?

Accepted Answer

Yes. TuoFu cleanroom chairs are available in a range of standard colors including white, grey, blue, and black. Custom colors can be accommodated for OEM orders with a minimum order quantity. White is the most common choice for pharmaceutical cleanrooms as it makes contamination visible and is associated with cleanliness. We can also provide chairs with color-coded components to support zone identification systems.

Question 6

What is the minimum order quantity for cleanroom chairs?

Accepted Answer

The standard MOQ for TuoFu cleanroom chairs is 50 units per model. For OEM orders with custom specifications (custom color, logo, special materials), the MOQ may be higher depending on the complexity. We welcome sample orders for qualification testing — please contact us to discuss your specific requirements.
