This is very heavy on solvent use but you can recover by distillation and reuse. The target compound is added in a bag or thimble, then placed in the dropping funnel, with the stopcock closed. If you heat your material in a vessel of solvent with stirring for 20-30 mins then cool it, then filter (Buchner) followed by a cold wash. A makeshift Soxhlet extractor can be made by connecting a pressure-equalizing dropping funnel to a boiling flask, and on top connect a reflux condenser. ![]() You will only recover 75-80% of your product in the first 3-4 extractions, after this your diminishing returns make it unfavourable but it is the only practical way. Each mason jar should contain at least 50 grams of wet mycelium. The crude alkaloid extraction process given here yields a brownish crystalline powder that is at least 25 percent pure. We will figure the average dose as 10 mg. The whole thing is a closed system but needs careful monitoring so that no vessel runs dry. The standard dose of psilocybin or psilocin for a 150 lb person is a 6-20 mg dose. This feeds into a distillation vessel to recover your solvent which feeds into a collection vessel which is heated and this feeds the pump. On a large scale (I used to go up to multi-kg scale for the production of fine chemicals from natural products) you can use the hot column method which needs a peristaltic pump to force hot (not boiling) solvent vertically up through a column of your material. You can buy larger soxhlet extractors, however these will only do so much. ![]() ![]() Although I know the entire process is built upon extracting the material until there is nothing left to yield, Is their a faster process?ġA: Do they have an apparatus that is able to hold a larger quantity of material, say 100G of powdered herbs.ĢA: Is there a more efficient (time wise AND total extraction) process for extraction of larger quantities of material than Soxhlet for the garage chemist? Although the soxhlet extractor is capable of holding 500ml volume I can really only fit 25g or so worth of material in the apparatus at a time I could have however potentially fit more but I am concerned that filling the chamber above the siphon arm would decrease the extraction process.Ģ. Sizing Up the Soxhlet Extractor Now that you udnerstand why a Soxhlet is such a great piece of equipment, let’s give you the low down by breaking down the Soxhlet extractor into its basic components. The extractor only yields about 25g of material. The Soxhlet extractor hooked up to a cooler of ice water to keep cold water cycling over the condensor. However, I have run into a few stumbling blocks that really slow my progress down:ġ. I produce craft herbal medicines and for me extracting ALL of the constituents out of the herbs is really important, so the reflux process really caught my attention vs cold percolation/maceration etc. ![]()

![]() 3, 4, 5 Refer to Table 1 for a depiction of the HEART score, its five categories of variables, and scoring. 3 In these two higher score categories, two distinct subpopulations were noted, including the following MACE rates: moderate-risk, with a score of 4–6, MACE rate of approximately 12–17% and the potential consideration of observation and further testing and high-risk, with score of 7–10, MACE rate of approximately 50–65%, and the consideration of urgent or emergent intervention. 3, 4, 5 These low-risk patients were categorized as appropriate and safe for ED discharge without additional cardiac evaluation or inpatient admission conversely, a higher score was associated with an increased MACE rate and warranted more additional evaluation and/or intervention. Low-risk patients (a score 3 or less) were found to have a low (1.7%) MACE rate. Scoring ranges from 0 to 2 in each of these five categories, with the lowest possible score of 0 and the highest possible score of 10. Based upon five different variables, a score is summed for the patient under evaluation, including history (H), 12-lead electrocardiogram (ECG E), age (A), risk factors (R), and troponin (T). Suspected ACS patients are evaluated with a standard ED focused history and evaluation. ![]() 3 This decision tool is considered rather valuable for several reasons, including its ease of application, ready availability of the variables under consideration, the focus on short-term outcome, appropriate for ED management, and the identification of three discrete sub-populations (low-, moderate-, and high-risk) of ED chest pain patients suspected of ACS. The HEART score was developed in the Netherlands in 2008 by Six, Backus and Kelder as a rapid risk stratification tool for patients with chest pain according to their short-term risk MACE (defined as acute myocardial infarction, need for percutaneous coronary intervention or coronary artery bypass graft, and death within 6 weeks ) to help identify low-risk patients, suitable for earlier ED discharge within 30 days of index ED visit. As is true of all such clinical decision rules, the physician should consider the information provided the HEART score yet exercise clinical judgment in the ultimate determination of management strategy in the adult chest pain patient suspected of ACS. The HEART score identifies patients at low, intermediate, and high risk for short-term adverse outcome resulting from ACS. The HEART score, a recently derived clinical decision rule aimed at the identification of risk in the undifferentiated chest pain patient, is potentially quite useful as an adjunct to physician medical decision-making. Many of these patients are low risk and can be managed non-urgently in the outpatient environment other patients, however, are intermediate to high risk for ACS and should be managed more aggressively, likely with inpatient admission and cardiology consultation. The challenge of acute coronary syndrome (ACS) identification with appropriate disposition is quite significant. Chest pain is one of the most common, potentially serious presenting complaints for adult emergency department (ED) visits. ![]() ![]() ![]() What’s the point of all this space exploration, according to McDonald? Scientists are busy performing a bunch of tests on the James Webb Telescope, including folding and unfolding its giant mirrors, so that it’ll be ready to launch in 2021. It’s possible the James Webb will manage to find another Earth-like planet out there, McDonald said. “In space, it will unfold like a flower and be able to see even further into space.” “In fact, its mirror is so large it had to be made in sections that fold up so it can fit into a rocket,” he said. The James Webb Space Telescope will be much larger than Hubble, McDonald said. The Hubble Space Telescope has provided amazing images of the universe for the past 30 years, but it’s soon to be replaced. ![]() Still, NASA has plans to put a new telescope in space in 2021. How does it work? It uses four mirrors to collect and focus light from distant objects.Īlthough the Hubble telescope looks a bit old-fashioned, “it was designed to be upgraded,” McDonald said.Īstronauts have visited it a number of times to do repairs, he said, which means it’s “actually far better now than when it was launched.” The telescope, which is the length of a school bus and weighs about the same as two elephants, is powered by solar panels. The Hubble Space Telescope has had a “profound” impact on our understanding of space and the universe as a whole, said Bob McDonald, host of CBC Radio’s science program Quirks & Quarks. (NASA, Jean-Baptiste Lacroix/AFP via Getty Images) According to NASA, their colours and shapes provided clues to help explain how the universe evolved. 18, 1995, Hubble returned this image of hundreds of galaxies that had never been seen before.

(NASA, Joe Maher/Getty Images for Bauer Media) A supernova is a large explosion that happens at the end of a star’s life cycle. When Lizzo turned 11 on April 27, 1999, Hubble caught this supernova on camera. (NASA, Michael Loccisano/Getty Images for TNT) 24, 2011, Hubble captured this image of a galaxy with a golden loop of sun-like stars inside what looks like a ring of smoke.
