A vacuum purge chamber has a stopcock valve that regulates the flow of your gas. Inside the vacuum chamber, you will find a support plate or rack that you can place your BHO on.

A vacuum chamber, on a commercial level, features shelving units where an operator can place multiple mats or trays containing a thin film slab of the extract. The indicator on the pressure gauge marks the pressure inside the vacuum chamber. In a vacuum, the pressure should read zero which is when the outgassing can begin.

The pressure should be about inHg. Most vacuums will measure the atmospheric pressure in inches of mercury. The vacuum pump sucks out the evaporated butane from the chamber. For the highest quality BHO, choose an oil-free pump that can handle the pressures and temperatures used in the vacuum purging process.

Choosing oil-sealed pumps can increase the risk of oil leaking onto the shatter or wax and ruining your products. Now, there are many types of vacuum pumps that produce different vacuum levels. Diaphragm pumps are the best choice for the cannabis extraction industry because they do not use any oil.

Plus, they are easy to maintain and are highly resistant to corrosion. Many diaphragm pumps are also quiet and can last for many years. While these pumps can be pricey , they can pay for themselves in the long run. Rotary vane pumps are an affordable alternative to diaphragm pumps. They produce an excellent vacuum and can be run for long periods of time. They can reach as close to a vacuum level as possible and feature positive displacement characteristics.

These pumps may have a lower initial fee, but may require additional maintenance costs because they use oil. For the best of both worlds, a hybrid pump takes elements of a diaphragm and rotary vane pump to provide a highly corrosion-resistant system. The rotary vane pump technology allows for the creation of the deep vacuum while the diaphragm pump part takes out the moisture before it can degrade the shatter or wax.

Oil-free and hermetically sealed scroll pumps are also a great choice. The motor and bearings are completely separated from the vapor stream and many are approved for cleanroom use. Finally, diffusion pumps are high-performance pumps that remove the gas molecules from the exhaust with a high-speed vapor jet. Single-stage and two-stage vacuum pumps differ in price but two-stage pumps feature rotors and vanes.

During the two stages, one stage creates the vacuum while the other stage cleans its system. In this case, the two-stage pump provides a deeper vacuum level compared to single-stage pumps. Two-stage pumps are a must if you want quicker outgassing of butane, a cleaner process, and less noise. A ball valve between the vacuum pump and the chamber can help keep any oil from the pump crankcase from spilling into the chamber.

The ball valve allows you to close off the vacuum line when the pump is not in operation. Extraction experts recommend installing an isolation valve, a vacuum gauge, and possibly a ball valve for backfilling from the atmosphere or a nitrogen tank with a filter to reduce contamination in the oil. A compound pressure gauge is a critical element of the vacuum pump system for making BHO. Invest in a high-grade gauge and calibrate it before starting the process and regularly.

Still with me? So total gs of 7 day dried trim, 6 cans of ml butane. It would be enough for or more joints or 15 large blunts. Here are pictures of the weigh-ins from the bubble hash. Fill the pot a third of the way. The secret here is to dissolve your hash into the vodka ahead of time. Place the completely dry material in a plastic bucket.

I only put grams in at a time. The gummies are closely comparable to store bought. I have one gram of BHO from the same bud and would love to cook with it. I put 4 coffee filters on the small end and pour acetone through the wide part and let it drain into Pyrex. More often, the yield falls closer to an ounce per pound. The better quality cannabis the better quality extract. Terpene profiles and isolates can be a great way to reintroduce the terpenes that were lost during the process, while also helping to improve the effect, smell, and taste of a concentrate.

Range: to Green Bud, or High Quality Trim. Connect it to the pump, put the chamber on the hot plate and turn the pump on to start the process. The results differ from one product to another. Extraction tube 3. For full functionality of this site it is necessary to enable JavaScript. It dissolves clean and is rather flavorless.

Hope this helped. But from my experience: 1 oz. Range: 0 to Weedhommy is the most legit cannabis dispensary with both wholesale and retail weed for sale. Return the jar to the freezer. It is Sour diesel strain. Depending on the flavour I sometimes dust my gummies with citric acid.

The opposite is true for larger batches. An eighth of weed will give you 30 doses of cannabis tincture. After breaking down the leaf to mulch, put it in your pot. Add sixteen ounces of water to every four ounces of butter. A normal ratio is grams per high quality oz of bud. This batch was live resin. When you shop in Washington D. An ounce is made up of 28 grams so a quarter of an ounce is seven grams. Vegetable glycerin is a sweet, thick liquid that is popular in a variety of foods and often used in cannabis tincture making.

Concentrate container Blasting 1 can of butane per ounce will not remove all of the essential oils. The easiest way to determine the amount of terpenes and diluent you need to add to your products. The pressure range for rosin sits roughly between and psi. Tip 4: Color is everything Cannabis resin can run through the end filter as a translucent yellow color in the beginning.

Flagg Well-Known Member. Trim n fluffy buds i usually end up with about I use a G pen so I like a nice shatter texture I don't make mine but I get half of the yield from the dude that makes it. I normally get a little over an ounce per pound of sugar shake.

So he yields anywhere between I found that different brands of butane actually effect the yield. Using my favorite brand id say i average about the same as you. Usually grams an ounce of shake and sugar leaves. GreenStick85 Well-Known Member. Hope you got a vac, I find just doing BHO alone is smelly. The product just reeks of the solvent and I've tried taking the most filtered stuff I can find around here.
