The five features below make this syringe su perior for storing, transporting, and injecting gas samples. Wherever we've demonstrated it and compared it head-to-head with other syr inges, it has proved its superiority. It has no equal for reproducibly delivering precise quanti ties. Ο IT IS LEAKTIGHT f r o m vacuum to 2 5 0 psi, and it stays t i g h t . Unique Teflon plunger with an internal O-ring for a lastingly resilient seal. No cold-flow leakage, as with other Teflon seals. © FRONT LOCKING mechanism. Two t u r n s of the nosepiece-valve handle locks-in the sample for storage, for transport, or for pre-pressurizing t o inlet pressure before injecting. © NO DEAD VOLUME. The Teflon plunger bot toms against the barrel plug at the zero point, insuring accurate measurement. © POSITiVE REAR PLUNGER STOP. Plunger cannot blow out of the barrel at high pressures. Stop is threaded for d i s a s s e m b l y , hexagonal flats prevent rolling and provide secure finger grip. © INTERCHANGEABLE PARTS. Special or re placement needles and other parts are available f r o m stock for on-the-spot maintenance or cus t o m modifications. Send for detailed literature today!
