Task and additional infomations:
- Get rid of the base from every pull while minimizing any loss.
- Its ok to get some base in your pulls as we will get it out with every pull.
- Sometimes the salt water does not grab the base drops. In this situations you could try to prepare another salt solution but basify it to ph 12 and then try the same cleanup

Tested with:
- Heptane and Naphtha

Equipment:
- Small jar A which should have the size of a single pull + 50ml (example: 150ml if you use 100ml pulls)
- Large jar B which can hold all cleaned pulls
- Jar S which will hold the salt water
- Table salt (no sea salt)
- Water
- Glass syringe (No plastic)
- A dull needle. Dull is imporant as you will get the small base drops easier out.
- Syrrange and needle should be as long enough to reach the very bottom of Jar A

Preperation:
- Preperation should be done hours before doing the first pull.
- Boil some water and dissovle as much Salt in it as possible in Jar S. There should remain salt at the bottom.
- Let content of Jar S cool.
- Put Jar S in the fridge.

Procedure:
- Do the first pull with your solvent as usual and put it in Jar A.
- Check if there are base drops in Jar A.
- If no then transfer to Jar B and do the next pull.
- If yes then continue with next steps.
- Suck 2-3 ml salt water from the very top of Jar S into the syringe. We dont want the undisolved salt in the syringe.
- Dive syringe into Jar A so the needle hits the bottom.
- Put salt water into the hot solvent in Jar A.
- Important: Dont shake the Jar A. Putting the water into jar A and getting it out is a 10 second procedure. Rotate the Jar A about 15° and let the water grab the base drops. Try to catch all drops in the jar. The water has to touch the whole surface of the bottom of Jar A.
- Rotate jar A about 20° so the water is all in one place.
- Suck out the water with the syringe and suck as much solvent out as it fits in the syrange. By sucking out some solvent we make sure we get all of the salt water and base out of the solvent. Sucking out some solvent also prevents the water to fall back into Jar A.
- Salt water should fall down in the syringe.
- Drop the salt water into your black soup or backsalted soup. Its ok if a few drops solvent fall into the soup as we are cleaing every single pull.
- Put the remaining solvent from the syringe in Jar A.
- Check if you are satisfied with your pull. If yes transfer solvent from Jar A to Jar B. If no do another water wash.
- Do next pull and same cleanup procedure.

Theory: (Not a chemist. Pls correct me if required.)
- Dmt has a high solubility in solvent but low solubility in water.
- Hot liquid can hold more substance then cold liquid.
- When the solvent is hot it can contain more dmt and when the water is cold it should grab less dmt.
- We use salt to oversaturate the water. An oversaturated water solution shouldnt grab any dmt.
- We use as less salt water as possible but as much as required. This will reduce the loss of dmt while washing your solvent.
- In case the water grabs some dmt it is also fine as we drop the salt water back to the soup.
