The FDA classes food grade ethanol sold at LabAlley.com as a Class 3 risk residual solvent because because it has a very minimal risk of acute or chronic toxicity in pharmaceutical manufacturing when the residue is less than 0.5% of the remaining finished product.
Many herbal products and botanical extracts are manufactured using an ethanol extraction method. This extraction method is inexpensive and quickest method for extracting botanical extracts and oils with very little ethanol residue.
Testing firms in the U.S. check for microbial contaminants and heavy metals in botanical products. Testing laboratories in the USA check for the presence of mycotoxins caused by molds, perform pesticide residue analysis and screening, perform residual solvent analysis and use infrared analysis to verify the potency of botanical extract products.
Chloroform was formerly used as an inhaled anesthetic during surgery, however, the main use of chloroform in USA industry is as asolvent. Around the glove, chloroform is also used in pesticide formulations, as a solvent for fats, oils, rubber, alkaloids, waxes, and resins, as a cleansing agent, grain fumigant, in fire extinguishers, and in the rubber industry. It is used as asolvent in organic chemistry, in photography and in making dyes, drugs and pesticides.
Heptane, ethanol and hexane are used by industrial botanical extraction facilities and plant processing facilities in the USA. Some botanical extraction equipment used at these facilities are compatible with ethanol, heptane and hexane. Heptane in 55 gallon drumsare sold online by Lab Alley and are used by large scale industrial agri-processing facilities.
Ethanol denatured with heptane is a high purity extraction grade. Ethanol and n-heptane are non-polar solvents. This extraction solvent is ideal the production of "crude extracts". Crude extract is an unprocessed material that must be refined by botanical processors to produce final products sold toconsumers. Crude extracts are produced using ethanol extraction or CO2 extraction. Note that heptane should be purged from final products and crude extracts.
Heptane is used in the USA to dissolve or remove waxes/ lipids during theextraction process. Because heptane is nonpolar it is a good solvent for extraction. Heptane’s boiling point is around 209°F, so it is important to properly purge the heptane before consumption. When processing plant material the first step is to dry it out and then soak it in the solvent until it dissolves. Then the extract can be collected from the solvent. Next is thepurging process, because hexane is not pressurized the purging process may take longer than usingethanol denatured with hexane. But using heptane as a solvent has its benefits. It creates a more potent and flavorful botanical oil. Lab Alley provides fast shipping in the USA. You can orderheptane for botanicalprocessing facilitiesin a 55 gallon drum.
Non-polar solvents such as hexane are used for botanical extraction in the botanical industry. Some botanical polishing applications require greater purity and potency, so it is desirable to remove inactive ingredients like fats, lipids, and plant waxes, as well as any chlorophyll and other water solubles by using hexane to re-dissolve and filter compounds extracted from plants. For more information on polishing extracts, click here.
Ethanol is also used in extraction processes. 95% HPLC Reagent grade hexane is used, along with water, to clean up or "wash" an alcohol extraction. Hexane must be evaporated, purged or scrubbed from botanical extractions for health and safety reasons.
Hexanecan be used as asolventand a wash in the botanical extractionprocess. n-Hexane is used to extractoiland other compounds from plant material. Hexane is used toremove chlorophyllfrom plant materials andextracts. The hexane extraction is a process frequently used in food industry andsoyfood processing. Hexane is a popular solvent for extraction of oils,chlorophyll, bioactive compounds and other constituents of plant foods. Hexane removes undesirable constituents from plant foods and solutions.Buy hexane for botanical oil extractionfrom Lab Alley online in the USA. In solvent extraction,n-hexaneis used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents. Hexane has been widely used for oil extraction because of easy oil recovery, narrow boiling point (63–69 °C) and excellent solubilizing ability.
It is important to understand thesafety and efficiencyof various extraction methods. Hexaneis highly flammable and explosive. It is important to use hexane in the correct environment and take the necessary safety precautions. Hexane should be used in a well-ventilated area or outside. People use hexane to produce a final product that is much more potent than the original herb. Whenusing hexane for botanical processingit allows the user to isolate more desirable compounds than the herb provides freshly harvested. The purpose of using hexane or other solvents such asethanol,pentaneorhexaneare to reduce the plant in solution then remove the chemicals. If done incorrectly the herbal oil and compounds can remain full of chemicals that could be harmful to the human body. In order topurge hexanefrom the finished product there are two options; heat and vacuum using thin film techniques or washing it infood grade ethanol. Hexane is ideal for dissolving the waxes and lipids during the extraction process. It is important to use a good grade of hexane or distill the hexane before using it for the extraction. This will produce better results in the end. You can purchasehexane for botanical processing and extractionat Lab Alley.
Methanol is the simplest alcohol, and a polar solvent used in the extraction of essential oil. Methanol has a polarity index of 5.1, making it useful in most bioactive compound extractions.
Lab Alley sells methanol in various grades, purities, and quantities on our website for customers across the United States. Among our clientele are small businesses, individuals, universities, and research and industrial laboratories.

Isopropyl alcohol is a polar solvent similar to ethanol that can be used to extract crude oil from flower buds. A crude oil is one that is "unrefined," and so a crude oil will include plant matter, pigments, and other flavonoids that may be undesirable in the consumer end product.
Below are our most popular isopropyl alcohol purities and quantities sold in our store.
Raw plant matter can be extracted of its active compounds using isopropyl alcohol in a process called a QWISO, or quick wash isopropyl. It is recommended to use the purest isopropyl alcohol possible, with purities at 99% if possible. Yields vary depending on how finely you've grinded the plant matter used, and whether or not you winterize the extract as a step in the process. You will need roughly 100 -200 mL of isopropyl alcohol for every 10 grams of plant material in this process.
Winterization is the use of cold temperatures and your active solvent to separate fats and waxes with higher melting points, further separating extracts from plant fibers, waxes, and fats. Processes involving isopropyl alcohol and ethanol can integrate winterization as part of the extraction process, while CO2 purges, for example, will have to refine the product through winterization and filtration afterwards.
Alchimia Blog, a blog operated by Alchimia Grow Shop in Figueres, Spain, advises against using isopropyl alcohol for performing extractions, emphasizing the toxic effects of ingesting isopropyl alcohol - even residual amounts. Instead, they suggest only using isopropyl alcohol for cleaning utensils, glass pipes, and other manufacturing equipment. Instead, they recommend ethanol for botanical processing.
