Teflon needle valve replaces awkward tubing clamps for a more accurate, dependable gas flow that is especially useful in multiple tissue bath systems

For applications requireing a single gas source to be distributed and balanced the Radnoti 120168 2-Way Teflon Needle Valve "Y" manifold offers an elegant solution. A borosilicate glass body and Teflon valve stems insure a chemically inert gas path. The individual needle valves offer a fine adjustment of flow to balance out delivery. Ground glass female luer fittings for inflow and outflow allow easy connection of tubing lines. A 3/8" glass rod fused to the manifold body allows for easy mounting on to most lab stands.

In repeated use, the sintered glass disc may be occluded by the components of physiological solutions and endogenously released substance from tissue preparation. The removable oxygen disperser tube makes cleaning easy and replacement convenient.
