Originally used for Lyophilizing and storing frozen slices of tissue for quantitative histochemistry (see O.H. Lowry, Journal of Histochem. & Cytochem., I, 420, 1953). More recently, used as a vacuum tube with aluminum holders by Nelson & Wakefield, Journal of Neuropathology & Exper. Neurology,…

All-glass-and-PTFE vacuum manifold with three, four or five stopcock ports. Each port is a variable opening, 0-10mm, high vacuum threaded stopcock. Plugs are PTFE with Nylon or PTFE handles and FETFE O-Rings. Ultimate vacuum of 10-7 can be realized with O-Rings as supplied. For bakable systems,…

The vertically mounted Carb Octopus air sampling manifold design features an inner tube which allows condensation to drip to the collection bottle and away from the #7 Ace-Thred instrument ports. Available in standard 4 or 8 port configurations.

Straight sampling manifold, available with one end threaded, the other end reduced for use with 7506 bushing, or both ends threaded for use with either 7506 bushing or 5841 coupling. Also available with adjustable depth, threaded sampling ports for use with up to 7mm O.D. tube. Code identifies I.D.…

For portable gas analysis apparatus. Three or four straight 2 mm bore glass stopcocks and one three-way stopcock with back port, fabricated on capillary tubing. We can fabricate special gas manifolds of all kinds.

Use to tip-off NMR tubes by inserting in lower Ace-Thred port and tightening via bushing. Vacuum line is connected to side hose connection. Tube is then tipped-off with flame. Aluminum shield helps retard heat transfer. Each port individually controlled by smooth acting, semi-needle, threaded PTFE…
