Sample-Seal Glass Liquid Sample Holder 50 ml, Graduated, 90 Degree, 0-4mm CG Valve, #9 Joint Flange

These graduated Sample-Seal liquid sample holders are used to store precursors that generate vapors to be flowed into the vacuum chamber. These liquid sample holders include 1, 0 to 4 mm adjustable high-vacuum CG valve which produces a leak-tight o-ring seal. They are designed with one 90 degree #9 O-ring joint outer diameter glass connections. These sample-seal liquid holders are designed to withstand pressurizing up to 50 PSI and are often used in molecular spectroscopy experiments to contain the precursor liquid samples before the spectrometer. For connections at the #9 glass joint flange they require a #9 O-Ring and pinch clamp size of No. 18 and require a #112 O-ring. Replacement o-rings are sold separately, please call 505-872-0037 for more information.
