Tech Tips by K2 - Vol. 3

  Clogs & Cleaning

 Don't you just hate it when your sink or toilet clogs and backs-up?  Don't you just want to scream and run from the room pulling your hair, only to realize that more loose hair means more clogging?  Don't worry 'bout it, thanks to better living through chemistry; specially formulated caustics and genetically engineered bacteria can solve and prevent many of these aqueous nightmares.  "But what about my titrator?" you may inquire.  When the delivery tip and tubing and valves clog and titrant flows freely from everywhere except where it's supposed to, whatever can you do?

    Not to worry old inquisitive one, the answer is there in front of you- CHEMISTRY !  When clogging occurs because of crystallization of reagents, the following procedure may be employed to alleviate the problem:  a) first remove the delivery tip or titration nozzle, tubing and/or burette cylinder;  b) dissolve the blockage by soaking it in the solvent system for which the titrant is being utilized (for those extremely pesky clogs, try utilizing an ultrasonic cleaner with the solvent);  c) rinse well with clean water;  and d) put it back together: don't forget to reassemble all parts before titrating again.

    That's great  you say for plumbing that easily accessible, but what happens when the clog occurs in the switching valve assembly?  Once again, the answer is CHEMISTRY !  First, disconnect all the tubing from the assembly.  Next, utilizing a dropping pipette, fill the valve ports with the appropriate solvent system.  After a moment, aspirate out the used solvent with the pipette.  Repeat as necessary until the valve ports are clean and free of the clog.  Lastly, don't forget to reassemble before you attempt to run a titration.

    If problems still exist, you can always contact the Roto-Rooter man or for better service, just give  K2 Analytical a call.
