Streamline cleaning protocols in high-grade cleanroom and critical manufacturing environments by reducing rinsing frequency with an active quaternary ammonium formulation that delivers efficacious sanitation at low concentrations.

Klercide™ Cleanroom Quat – Blended with WFI
Uniquely formulated to minimize residues and reduce rinsing frequency.
Product Information
Features and Benefits
- Minimal-Residue Quat Formulation
Active quaternary ammonium molecule is efficacious at low concentrations, with significantly less residue accumulation, with non-corrosive material compatibility for use in most cleanroom applications. - Reducing Time and Cost to Clean
Helps reduce the need for frequent or daily residue removal step, streamlining cleaning protocols to reduce labor and time costs associated with more frequent rinsing – making it ideal for sanitization of hard surfaces in cleanrooms, controlled environments, isolators and other critical equipment. - Minimize Residue Associated Risk
Non-phenolic formulation features no hazard warnings and does not require the use of PPE when used according to label directions. Reduced residue also mitigates slip-and-fall risks associated with sticky residue buildup. - Sterile Delivery System
Trigger-spray format features patented SteriShield™ Delivery System (SDS), providing sterility assurance of contents in bottle by forming a complete seal that prevents any air from (and microbial or chemical contaminants) being drawn back into the bottle. - Cleanroom-Grade Production
Both trigger-spray and capped-bottle formats are 0.2 micron-filtered and sterile-filled under unidirectional Grade A / ISO Class 5 airflow in a Grade B / ISO Class 7 cleanroom – and available double or triple-bagged to simplify movement into high-grade areas. Supported with Certificates of Analysis and Sterility with every batch.
