These NVacuo manifold systems provide the best solution for gas distillation and dynamic setup environments. Easily configurable with all other NVacuo products, this manifold has 8 Inch spacing between each of its four bottom #15 O-ring joint flanges. Each is also equipped with 0-4 mm High Vacuum Valves with O-ring on tip making it easy and simple to attach U-tubes for holding samples with the standard NVacuo Tees and Elbows built with the easy to use Universal O-ring joint flange design. This design means no hassling with glass end tubes and compression fitting adapters for every glass connection. The manifold is also designed with two top #15 O-ring joint flanges for mounting pressure gauges, as well as two main #25 O-ring joint flanges at each end of the manifold for pumping down the system and releasing gas samples for percent concentration measurements. The #15 joint flange requires #116 O-ring and No. 28 pinch clamp. The #25 joint flange requires #214 or #217 O-ring and No. 35 pinch clamp.
