Under normal operation, your RapidStill II will require little routine maintenance.
The following maintenance schedule is recommended:
After Every Day
(1)
Rinse the caustic pump, its delivery system and the distribution head as
follows:
(a)
Install a clean empty digestion tube in place. Remove the caustic
supply tubing from the caustic vessel and place it in a vessel of
purified water.
(b)
Turn on the cooling water and fill the boiler as described in
Chapter 3: Normal Operation
.
(c)
Turn on the boiler heater.
(d)
Depress ‘NaOH Addition’ switch and hold it on until all of the
caustic has been purged out of the system and into the distillation
tube.
(e)
Remove the digestion tube and dispose of the liquid appropriately.
(f)
Replace the digestion tube and fill it approximately half full by
depressing the ‘NaOH Addition’ switch.
(g)
When the water in the boiler is at a rolling boil, turn the distillation
timer to approximately 10 minutes.
(h)
At the end of the distillation cycle, turn the boiler heater and the
cooling water off. Remove the digestion tube wearing appropriate
heat and chemically resistant gloves. Dispose of the liquid
appropriately.
(2)
Clean the exterior surfaces of the RapidStill II using a soft cloth and a
solution of mild soap and water to remove any spilled chemicals or
deposits.
