TLC test of oil products

After extracting a series of oils from different plants at various temperatures we analyzed them under TLC. We clearly identified chlorophyll and saw how the amounts changed as a function of extraction temperature. Plant waxes were also reduced at lower temperatures. 

We are currently getting access to GC-MS at the local universities to further study the oil contents. 

Mock-up time

We spent a few days hunting for old copper parts on scrapyards and found some usable parts for the evaporation chamber. The heatsinks we are going to use also arrived. It was a great feeling to put all of the parts on a table and actually get a visual of the whole setup. This will definitely end up as top-of-the-pop steam punk design :-)

Meanwhile the electronics schematics were finished and the first print layout has commenced. 

Rhino Sketchup 1.0

All the major components has been selected and the first sketch has been made. The inital ideas was to use both squared and round units. To improve esthetics we have chosen to use rounded and elongated shapes. Once the sketch was completed, it was quickly realized that some of the initial topology ideas would not work in real life. After a few iterations we have a very crude steampunk looking concept we will continue with.

We call it Frankenstein :)

Temperature and purity

When extracting with ethanol a light and more yellow color means an absence of chlorophyll and other plant parts. These experiments were carried out on Cannabis. In many types of Cannabis extracts, such as oil for medication, chlorophyll is undesirable.

The image above represents three different extractions. One done at -5 degrees Celsius, one at room temperature and one at elevated temperatures. The image pretty much speaks for itself.

The amber color ethanol was produced using Frankenstein.
