Low Particulate, High Purity, Recirculating Faucet

      Fabrication of a high purity, low contamination, continuous
flow faucet is described.  The faucet is all Teflon (du Pont
trademark) construction with a diaphragm valve to control the flow
and a continuous flow assembly to maintain flow in idle state.

      Fabricate a bench-mounted faucet to dispense a high purity, low
particulate deionized (DI) water.  The faucet is constructed of
Teflon tubing with a modified diaphragm valve 1 to regulate the flow
without causing contamination in the DI water.  The faucet has a
continuous flow assembly 2 to maintain a flow of DI water through the
faucet while in idle state.  This assembly 2 is a fitting to allow
the supply of DI water to be inputted into the faucet with a smaller
Teflon tubing fed through the supply line 3 to the manual diaphragm
valve 1 to provide a continuous return flow exit 4 while the manual
valve is closed.  The continuous flow of DI water assures high
purity, low particulate even while faucet is in idle state (see the
figure).
