The Low-Leak Diaphragm Pump (A0702) is an essential part of a closed-loop measurement system. It helps enable Picarro analyzers to provide high-precision isotopic carbon measurements in applications where controlled, recirculating gas analysis is essential. 

• Specifically designed for recirculation with minimal leakage 
• Stainless steel tubing and fittings included
• Optimized to provide a total volume of only up to 100 mL for the system

The Low-Leak Diaphragm Pump is specifically designed for recirculation with minimal leakage. Stainless steel tubing and fittings are included so that a closed-loop measurement system is optimized to provide a total volume of only up to 100 mL for the analyzer, pump, and tubing. The Low-Leak Modification Kit (A0701) is required for the Picarro G2132-i isotope analyzer to function as part of a closed-loop measurement system.
