ACT Distillation Head Specifications



ACT Distillation Head


  • Join sizes on everything, providing a true “full bore” vaccuum pathway
  • .5-1 liter/hour on the 2 liter test system 
  • Average temperature of distillation 170 degrees in boiling flask
  • ACT system has superior vaccuum integrity due to high quality glass joints and quality control 
  • Average vaccuum level at distillation is 10-20 microns, decreasing vaccuum level 
  • ACT system if suitable for “Hot Condenser Tech” if desired
  • Valve post on ACT Unicow distribution adapter retracts out the vapor pathway to not interfere with the “full bore” vaccuum pathway

ACT Thermowell

This thermowell fits the top port of the ACT Distillation head. It provides a secure, vaccuum tight method to monitor the vapor temperature of your distillation. Use an appropriate heat transfer fluid in the thermowell.

ACT Distillation Head Separation Ability


  • Starting material is warm EtOH extracted 1 year old biomass
  • Tests conducted on real-world, low-end starting material to give a true representation of a situtaion many extractors experience
  • Starting material is not winterized or filtered through clays and powders
  • Ommited filtering in the process to allow head to show its separation capabilities

Data From ACT Short Path System Testing

  • The average distillation speed on a 2 liter system loaded with 1 liter of crude is .5 liters/hour once the heads fraction has been removed. This is using an old Alcatel pump. 
  • Higher flow rates are achievable using faster vacuum pumps 
  • Average boiling flask temperature is 180 degrees Celcius for distillate to begin to flow into the condenser. The temperature is then increased if a greater flow rate is required. Lower temperatures are possible if a greater purity is desired or a greater separation gradient is needed. 
  • Using testing from Boanicor, the avergae distillate is 70%+ CBD prvided that vaccuum integrity is preserves. 
  • If vaccuum leaks are not addressed, potency will suffer, although this can beremediated with a subsequent distillation pass.

 ACT Short Path System Specifications


  • Uses a modified Oldershaw column to produce true fractioning distillation. The head itself contains (1) modified Oldershaw plate which provides a surface for the vapor to condense onto and allow heavier, undesirable compounds to remain a liquid and drain back into the boiling flask.
  • The custom packing inserted into the head provides between 3-5 additional theoretical plates for greater separation power.
  • The tail dragger is primarily for cleaning up tails or for particularly dirty or poor quality material. 
  • The condenser jacket extends directly to the distillation column on the head, ensuring smooth fast flow with no cold spots. 
  • Custom ACT cold trap functions. The cold trap is vacuum jacketed and thermally insulated with elemental silver. There is a spiral cold finger that directs the vapor flow all around the cold trap so that significantly more surface area is in contact with the vapor stream.
  • A molecular sieve component adsorbs many head compounds utilized on a first pass, installed between the cold trap and the “unicow” distribution adapter. The molecular sieve beads can be removed from the component for cleaning or fresh beads can be added.
