38mm Vacuum Sampling Pumps

When extracting higher-viscosity oils or drawing large-volume samples, our 38mm Head Vacuum Sampling Pumps provide maximum draw efficiency and reliable system connection. Operating on the proven "thief pump" principle, fluid is pulled directly into the sampling container through flexible tubing, keeping the internal cylinder entirely free from media contact.

This versatile 38mm thread platform connects directly to standard 38mm neck sample bottles and system adaptors, eliminating the risk of external ambient contamination during field collection.
