SS304 – Full Cleaning Validation Description SS304 Cleaning Validation Coupons are designed to represent SS304 Cleaning Validation Coupons replicate the most widely used stainless steel surface in pharmaceutical equipment. They represent 18-8 chromium-nickel steel surfaces found in tanks, pipelines and contact parts. SS304 offers good corrosion resistance and stable residue recovery under GMP conditions. Used for swab recovery, rinse recovery and detergent effectiveness studies. Ideal for validating cleaning procedures on standard stainless-steel contact equipment.. They are used in pharmaceutical, bioprocess, and GMP-regulated systems to assess residue recovery, detergent compatibility, and cleanability of equipment surfaces made from SS304. These coupons support RF% studies, swab and rinse recovery validation, and regulatory documentation for cleaning procedures involving this material of construction. ✔ KEY PURPOSES • Establish residue recovery factors (RF%) for SS304 surfaces • Validate swab and rinse recovery in GMP cleaning procedures • Assess chemical compatibility with detergents and disinfectants • Provide FDA/EMA/PIC/S-compliant cleaning validation documentation • Ensure robust justification for equipment made from SS304 ✔ MATERIAL CHARACTERISTICS • Material behaves as described in its summary: SS304 Cleaning Validation Coupons replicate the most widely used stainless steel surface in pharmaceutical equipment.
