Frequently Asked Questions

Q: How do ISO machines work?

A: The machines are designed to extract the essential oils from any plant or herb. The basic extraction is accomplished by gently washing warm alcohol thru the herbal mass until all of the essential oils are dissolved in the alcohol.  Then the alcohol is removed from the mixture, leaving behind the extracted oil. 

Equipment and instructions are provided to further refine the basic extract and make it into the concentrate products that are popular today.

Q: What form of oil do the machines make?

A: Instructions and equipment are provided to make all of the different concentrates and extraction products that are currently popular for both medicinal and recreational use. 

The machines are designed to produce several different forms of extract products. The simplest process produces thick, dark extract known as “whole-plant oil”. This is a medicinal product containing all of the elements (terpenes, chlorophyll, waxes, etc.). It is often called RSO.

Pristine oils and vaping products can also be made with the ISO machines. Translucent/ amber and clear oils can be extracted and isolated. These oils can be processed into the popular vaping products known as budder, wax, or shatter.

Q: How do the ISO machines compare with closed loop butane extraction machines?

A: The ISO machines are an alternative to the dangers and high costs of butane and CO2 extraction devices. Butane has developed a very negative image in the past few years. The gas is extremely flammable. Countless fires, explosions, and burn injuries have resulted from butane extraction of cannabis. Humboldt county has outlawed sales of butane.

Another problem with butane is the residue left behind in the product. Expensive vacuum ovens are used to purge the final traces of butane.

The ISO machines use ethanol (drinking alcohol) as a solvent. It is many times safer than butane as it is a liquid and not a gas. While ethanol is easily removed from the oils, residual traces are no problem at all as they would have the toxicity of a tiny sip of weak beer.

The ISO machines operate at normal atmospheric pressure. Butane extractors operate at up to 100 pounds of pressure; CO2 equipment can require up to 2000 pounds of pressure. 

Q: What is the efficiency of the machines?

A: Instructions are provided for the practical extraction of 100% of the alcohol-soluble essential oils contained in the plant. This is superior to the inefficiencies of other extraction techniques and equipment, which often leave a substantial amount of desirable elements in the plant waste which is discarded.

Q: How long does it take to complete the extraction, as compared to butane extracting?

A: Butane extraction is much faster, whether a closed loop system or open blasting with tubes. This is because butane is simply run thru the herbal material, then evaporated into the air, or collected with more sophisticated equipment.

There is substantially more work and time involved when making pristine extracts with ethanol using the ISO-3 or ISO-4. 

When making whole plant RSO, however, there is very little work involved while the machine runs with attention for 8 to 24 hours, depending on the type of extraction being performed.

Q: How much herbal material will each machine process? 

A: The ISO-3 Quartermaster will process a quarter pound of loose, fluffy herbal material, up to a half pound if the herb is macerated or tightly packed.  

The ISO-4 Kilomaster will process a kilo of loose material, up to five pounds per run if the material is macerated or tightly packed.

Q: What are the yields of the machines?

A: This varies according to the material used. 

Many Alchemists are realizing upwards of 250 grams of RSO from a kilo of resinous trim. 

The ISO-3 can yield whole plant oil at a rate of about 20% of the weight of the starting material.

Q: Do I need a vacuum pump and oven to purge the remaining solvent from the oils I produce?

A: Instructions are provided for removing all the solvent from the final product. 

Ethanol (drinking alcohol) has been chosen as the solvent of choice due to the lack of toxicity of any traces which the operator may inadvertently leave in the oil. 

Q: Can I choose between making dark whole-plant oil (RSO) or pristine oils or products like wax, shatter and budder?

A: One can easily make pristine oils at the beginning of the process, and then remove all the remaining desirables in the form of whole-plant oil.  This allows the extraction and capture of all of the desirable elements present in the herbal material.
