3 Easy Steps for Safe Solvent Extraction


In the botanical industry, there are many options available for extracting soluble components of plants. However solvent extraction is the easiest, most inexpensive and fastest method. Solvent Extraction as the name says is extraction of essential oils from plants by using a solvent. Solvent extraction is also considered to be the safest forms of extraction process and provide quite similar results compared to other options available. This process is used on plants that cannot resist heat and thereby making it easy to capture their fragrances.

Steps to follow for a safe, easy and fastest extraction process:
Ethanol is a one of the widely used and most popular high-proof alcohol used for solvent extraction.

It is safe to use it for infused edibles and at the same time can be used with any type of container. Ethanol is well-known to provide uniform results and is easily recoverable from the substance.


Step 1: Soak  
Soak the plant material completely in the ethanol and leave this mixture for 24 hours in an ultralow temperature freezer. Observe what happens. The soluble components will separate effortlessly from the ethanol.

Step 2: Filter
With a Buchner funnel and a vacuum flask remove all the solid materials. This will leave behind a solution of ethanol and extract remains.

Step 3: Set Apart
Using a rotary evaporator, the extract needs to be separated from the ethanol. For quicker evaporation connect the rotary evaporator with the vacuum pump. The resulting extract will be completely free of ethanol. A variety of rotary evaporators are available ranging from laboratory research use to large scale production plants. A Heating bath could be purchased separately to accelerate solvent recovery.
After going through all the above steps of extraction, the extract is now ready for the next phase of the process.

Process for a purer extract
A process of winterization is recommended for a purer extract of essential oils from the plant. In this process, the fats, plant lipids or any kind of waxes are removed from the extract remains. At this stage, ethanol can be added to the extract, repeat the filter step followed by the rotary evaporator to boil off the ethanol. This is the purest version of the extract that can be further dried in a laboratory oven or readily infused.

Note: A distillation apparatus will require recirculating chiller to keep the ethanol at the appropriate temperature.

Care of Spectrophotometer Cells

Cells or cuvettes are optical instruments used in the spectroscopy. These cells are manufactured with great skill, uniformity, and maintain high quality standards. Hellma is dedicated to meet the requirements and maintain the standards. Cell and other related components pass through various inspection procedures. The raw materials also undergo certification before the manufacture and packaging of these optical cells. It has been observed that general use of cells lead to gradual degradation of precision surfaces. In spectroscopy, it is very important to have a good optical cell as it helps in providing accurate results. There are different types of solvents which mainly affect the optical cells. The use of high alkaline as well as high acidic solvent fastens the degradation of hardest glass as well as quartz cuvette. The inefficient cleaning or mishandling of these optical cells can also lead to result inaccuracy and related complaints. Hellma uses borosilicate and fus...

Features Of Analytical Balances That Can Be Used For Research Purposes

A scientific research environment needs absolute precision.   These research activities require absolute and accurate measurements of different factors such as temperature, timing and weight. The use of modern technology in manufacturing various testers and measurement devices have led to authentic products like analytical weighing scales, digital thermometers and other measuring instruments that give precise and absolute readings. Analytical balances are the sought-after devices for scientific research purposes. These balances are very accurate and show readings up to seven decimal places. Such accurate readings are very essential for success of an experiment. Along with being accurate, analytical balances are also functional. These balances are able to read the weight of the samples and show minor dispersions on the scale platforms as well. The most important feature of RADWAG analytical balance is its zeroing capability. An ideal balance should take less than five s...
