850705 Conducting Indicator Student Conducting Indicator
Blinking LED Conductivity Indicator. This LED (light emitting diode)
conductivity indicator is sensitive enough to respond to as little as 0.1
ml of liquid. It will detect free H+ ions in water, and will even register
low conductivity for 70\% ethyl alcohol. When both probes are in
contact with a solid or immersed in a solution, and the material is a
strong indicator the LED will glow red and blink rapidly; if the material
is a weak conductor the LED will have a steady dull glow; and if the
material is a non-conductor the LED will not light up. Requires a 9-volt
battery (not included). 1-year limited warranty. LA300 $19.49 each

Eyewash Adapter \\&
Hand Protector Gooseneck Eyewash Adapter
Eye Wash Fountain Fixture. Dependable, effective eye wash fountain is
easily installed on existing faucets without additional plumbing. The
diverter, which replaces the existing aerator on a faucet, is designed so
that the pull of a button directs two streams of water upward into both
eyes simultaneously. It closes automatically when the faucet is turned
off or the button is pushed. The unit is in two pieces, so the eyewash sits
behind the spout, out of the way of everyday use but in position for an
emergency. Removable fountain tips and aerator make cleaning simple.
Chrome-plated brass unit has male/female threaded universal adapters
for installation to outside or inside threaded faucet tips of varying
dimensions. Tip covers protect against foreign objects and slide off with
the first thrust of water. Meets ANSI Z358 Standard. WLS33816-05 $44.87 each
