Laboratory Water Testing

SGS is the leading provider of laboratory water testing and pharmaceutical water system validation services.

If manufacturing plants are located near any of SGS’s Life Sciences Services laboratories, our technicians can perform the sampling for you. Alternatively, your staff can collect the samples and ship them to an SGS laboratory for analysis. We can supply containers for collecting water samples.

Your samples for microbiological testing will be put on test schedule the same day we receive them. Bacterial endotoxin and chemistry testing will be completed within five working days. Please contact your local laboratory from our network to discuss your purified water system validation requirements.

All water purification systems must be monitored regularly to verify the quality of the water produced. Water purification systems can potentially harbor high levels of bacteria and bacterial or chemical purity problems with water can compromise the quality of finished products. We can carry out the following water monographs on your behalf as part of our purified water system validation services:
