THE BEST HAND HELD NEON TUBE MERCURY INJECTOR AVAILABLE! BRAND NEW STOCK DIRECT FROM MANUFACTURER! NOT "NOS" (New Old Stock) OR SURPLUS. THE SVP NEON TUBE MERCURY INJECTOR • NO CONTAMINATION - ALL WETTED PARTS ARE INERT • FLEXIBLE PTFE (TEFLON) NEEDLE • HOLDS APPROXIMATELY 2 ml. - ENOUGH FOR 100+ NEON UNITS* • EASY TO REFILL - TAKES ONLY SECONDS • PRECISION THREADED GLASS BODY & CONTROL KNOB Our hand held NEON TUBE MERCURY INJECTOR is constructed of Pyrex glass, High-Purity PTFE (Teflon) and Kel-F. All wetted parts (ones that come in contact with the mercury) are inert: glass, PTFE and Kel-F. Inert is chemically defined as "Exhibiting no chemical activity; totally un-reactive". The use of chemically inert components prevents the mercury in the injector from becoming contaminated, even after extended periods of time of the injector not being used. The unit provides precise control over the amount of mercury inserted into a neon tube mercury trap by a simple turn of the control knob. Each drop dispensed is approximately 25mg. (0.002ml. in volume). Using 3 drops of mercury per neon unit*, a full injector will hold enough mercury for 100+ units. To refill the injector, simply insert the flexible needle into your supply bottle of mercury and turn the control knob counterclockwise. The mercury will be sucked into the injector body. When not in use the injector stands upright as pictured. As an added featured, the Teflon needle is transparent which allows the user to see where the mercury is inside the needle. The mercury can easily be retracted all the way, or part of the way back into the injector body after every use by a simple turn of the control knob, thereby eliminating droplets of mercury creeping out of the end of the needle - something that is a problem with syringe type injectors with stainless steel needles. As supplied, the Teflon needle is 12" long and can easily be cut to the desired length. As with all sizes of glass tubing, tubulation glass contains dust, water vapor, condensed oxides from the drawing process, and other contaminants on the interior surface of the tubing. The flexible needle allows the user to insert the desired amount of mercury directly into the mercury "bubble" or "trap" eliminating contamination of the mercury caused by rolling it through the dirty, contaminated, unheated portion of the tubulation glass. If too much mercury is inserted into the trap the flexible needle also makes it possible to suck some out. The use of inert parts eliminates the mercury contamination commonly found in syringe type mercury injectors that utilize a stainless steel needle. Research at the University Of South Carolina, Department Of Chemistry, revealed that after prolonged contact with even high purity stainless steels mercury 'salts' will begin to degrade the surface of the metal thereby promoting contamination of the mercury inside the needle. This contaminated mercury inside the needle is the first to be inserted into a new unit. Simply stated, contaminated and dirty mercury will produce contaminated and dirty neon units. * 3 drops from the injector is approximately 75mg., the amount SVP recommends for an average size neon unit. NOTE: The end of the tubulation glass should be lightly fire polished to avoid damage to the needle. With a properly adjusted cross fire or cannon fire this should take no more than 1 or 2 seconds. It does not have to be perfect or 'pretty', just enough to take to take the sharp edge off the glass.
