External Laboratory Testing

TestDescription
Bioburden TestingNative bioburden on as-received, non-sterile product is characterized and enumerated.
Biological IndicatorsInoculation of actual product can be performed or a process challenge device may be used.  Direct enumeration or fraction negative results are reported and interpreted.
Feasibility StudiesEngineering cycles performed with no guarantee of sterility.  Biological indicators are included and samples are returned for customer evaluation.
Materials Compatibility – FTIR SpectroscopyFTIR spectroscopy is used to characterize any residues and interactions between the sterilant and polymeric materials.
Extraction of Residuals / Residues Extraction is carried out to quantify the amount of residuals and residues on product.
