Rugged, unibody design has fewer connections, minimizing the places leaks could occur. All-stainless-steel construction means easy cleaning and no contamination from degrading O-rings. Simple to operate and easy to maintain, so you save time and money. Samplers ship leak tested ( 1 x 10-6 mL/sec) and ready to use, reducing equipment prep time. Individually laser etched with serial number and flow rate—no more guesswork from lost tags or labels.
