Cleaning verification swabs are special tools for cleaning verification
Both swabs and swab sampling use fibrous materials (most commonly used) to wipe surfaces.
It is typically used to verify that a cleaner or disinfectant performs as specified on a specific surface. In sectors such as the medical, pharmaceutical and food industries, cleaning verification swabs are a vital task as they ensure that environments and equipment meet hygiene standards, safeguarding public health and safety.
During the wiping process, residues from the surface are transferred to the fibrous material. The fibrous material is then placed in the solvent and the residue is transferred to the solvent. The solvent is then analyzed for residues by appropriate and validated methods.
What are cleaning verification swabs made of?
Cleaning verification swabs usually consist of a swab shaft and a tip.
The wiping head is made of special material that absorbs particles and organic matter remaining on the surface. When using a cleaning verification swab, first soak it in detergent or disinfectant, then gently scrub the surface to be verified, and finally send the swab tip to the laboratory for analysis to determine whether the cleaning effect meets the standards.
The fibrous material of the swab is textile (knitted, woven or non-woven) with a plastic handle.
Recovery of surface residue also depends on the size and shape of the swab head and the properties of the handle (e.g. elasticity and length).
In most cases, moisten the swab with solvent before sampling the surface.
The solvent selected should help dissolve the residue and be compatible with the analytical method.
For example, for HPLC analysis, the solvent should be the mobile phase of choice. For organic carbon and conductivity analyses, the solvent of choice is generally water.
To obtain higher recovery of surface residues, companies typically choose to sample the same surface with multiple swabs.
In this case, the other swabs or wipes can be dry or wet with the same solvent.
