SimpleDist® Micro Heating Block: Operation & Instruction Manual Distillation Methods
Total Phenol Distillation with the SimpleDist® Micro Heating Block
5.12 Allow the tubes to cool for 10 to 15 minutes. You will notice ne condensate begin to
appear on the inside walls of the collection tube.
5.13 After the tubes have cooled to ambient temperature, use the trapping solution inside
the tube to rinse the tube walls and collect all the condensate. This can be best
accomplished by holding the tube horizontally and then tilting the ‘Distill’ end a few
degrees downward. Slowly roll the tube while tilting it back to level and then the
‘Measure’ end down. You may need to gently tap the tube to knock down any drops
that cling to the edges.
5.14 With the ‘Measure’ end down snap the tube at the break joint. The ‘Distill’ end may
now be discarded.
5.15 Use reagent water to dilute the distillate up to the 6 mL line on the ‘Measure’ end.
Gently swirl the solution to mix.
5.16 Due to limited sample volume, the analysis is best suited to discrete or ow injection
analysis. Plug the end with a stopper or cover with Paralm® if the analysis will not be
performed immediately.
5.17 After use, clean exterior surfaces of heating block with a damp sponge. For acid spills,
sponge with a diluted solution of sodium bicarbonate followed by distilled water. For
caustic spills use a dilute solution of acetic acid followed by distilled water.
