A complete system of liquid chromatography chemical and biological preparative and determinative Unique threaded glass-to-plastic f i t t i n g s interchangeable within each diameter couple leak-tight by hand pressure by means o f inert " O " ring seal Easy assembly without springs or clamps. Internally threaded glass parts and nylon "O" ring couplings screw together in firm but not rigid engagement to make a positive seal at pressures far above those normally used for chromatography. The system features an unusual variety of end fittings which provide means for the introduction of controlled atmospheres or pressure drop controls. Syringe introduction of samples is possible through a septum side arm; eluent samples can be withdrawn by the same means. The septum can be re moved and replaced with a side arm feed tube for dual or alternate flow. Platinum wire electrodes can be intro duced. Adjustable height feed tubes allow various pack ing heights to be employed with one column. A poly ethylene float receives the droplets and prevents agitation at the surface. The rapid flow porous polyethylene or Teflon® standard packing support has straight through holes which retard mixing. The stopcocks are Teflon clad and require no lubricant. All components are described in the Ace October bulletin—send for your copy.
