Connecticut Clean Room Corporation (CCRC) introduces its Pur-Comfort anti-fatigue mat specially designed to prevent fatigue in con- trolled environments. The Pur-Comfort Mat #504 is certified for use in Class 5 cleanrooms, is made of autoclavable, 100% premi- um molded urethane, and can be cleaned with pre-moist- ened alcohol-based cleanroom wipes. Tested for dynamic head- space outgassing and extractable non-volatile residue, Pur-Comfort passes with a low level of total organics, and offers static dissipative properties for critical environments where static is an issue.
