Seal flush well water

As mentioned above, the defective pump was shut down early Monday morning before sunrise, and the mechanics started work about 10 30 A.M. on Tuesday, after the equipment was locked out. The pump was idle for about 28 hours before the well water seal flush was disconnected and the mechanics started disconnecting the 400-hp electric motor. 

The noble gases dissolved in water, as well as the halogens and hydrogen, carbon, nitrogen, and oxygen (as elements or in a number of compounds) can be flushed from the solution with an inert gas for collection. Radon is carried from previously sealed radium-containing solutions to measure the activity of its Ra parent (Curtiss and Davis 1943), as discussed in Section 6.4.1. Fission-produced xenon and krypton radioisotopes and neutron-activated Ar are flushed from samples of reactor coolant water, collected as the gas, and counted. Similarly, in the form of dissolved CO2 or CO is flushed with an inert gas through the distillation system and collected in NaOH or NaaCOs solution. Mercury salts can be reduced to the metal, processed by steam distillation, and collected as liquid mercury on a cool surface. 

Use reagent-grade solvents and deionized water. Pyridine is unstable and should be stored under nitrogen. Flush the bottle with nitrogen and seal the cap with Parafilm after use. Pyridine should not be used if it is very yellow. Buffers may be prepared well in advance of electrophoresis, but should be stored in glass bottles with airtight lids. After buffer preparation the pH should be checked. The pH value may vary...
