Ensure the sample is representative
- Take the sample directly from the coolant vessel/installation. Allow first a short run time of the coolant through all tubes and pipelines. If a filter is present, sample just in front of the filter.
- A simple plastic syringe or pipet is in most cases convenient for samling. In some cases, a vacuum pump can be beneficial.
- In case of multiple or repeated samples, always sample at the same point, using the same method. Flush properly in-between samples.
- Sample at least 125ml.
Protect sample integrity and exclude contamination
- Always use a clean and dry sample bottle, fit-for-purpose. HDPE is recommended over glass or PVC bottles.
- Label the bottle properly.
Handle safely
- Make sure to let the coolant vessel/installation cool down to a safe manipulation temperature.
- Check the key SDS information of the coolant.
- Wear the appropriate PBE (personal protection equipment) prior sampling. We recommend minimum safety glasses and gloves.
- Label the bottle as per SDS. Close the bottle firmly.
When you sample is ready for shipment, send it to our lab. Check out our shipment guidelines here.
