If it turns white and cloudy as you twist it is no good to use in a vacuum. One way to tell if the silicone has plasticizers in it is to pinch and twist the silicone. Cheap silicone has plasticizers in it, and the will leech into your oil and make it take like rubbery hell. It is crucial you only use high-quality silicone in a vacuum chamber when learning how to vacuum purge BHO. This is very similar to the process we are trying to achieve. One example of a ready made vacuum chamber and pump combo can be seen here degassing silicone. Just read up on descriptions and ensure that it is strong enough to pull the desired vacuum. Ideally, you will be moving towards an oilless vacuum pump, avoiding the oil break down from solvent being pulled through the pump, and any chance of oil being pulled back into your dab. You can have terrific results with a regular two stage vacuum pump, and keep getting better the more you are willing to invest. Once you have a vacuum chamber you will need something to run it, specifically a 2 stage electric vacuum pump. If I was making larger batches, this is the kit I would go with today. Remember to leave some room for expansion as your solvent boils off as the BHO tends to bubble and rise up, forming a ‘cookie’. I recommend staying with a metal chamber, just get the size that makes sense for your batch size. There are some companies that sell them with Pyrex glass chambers, but I don’t like that idea as a little crack turns into a big problem under vacuum. If you are more of the pick up a thing that someone who knew what they were doing built type (like me), You will want to head toward pre-made vacuum chambers. If you have the skills, this is a great option for customizability and scalability. Be forewarned you will need some machining experience, and general handiness to pull this off and get a perfect seal. If you are the handy type and see value in creating things from scratch, here is a great video on making a vacuum chamber. The next step up is a purpose made vacuum chamber and an electric pump. Vacuum Chambers for Vacuum Purging Homemade Vacuum Chamber Purge If you are making small batches for personal use, this is a fine option, and should be readily accessible when learning how to vacuum purge BHO. In practical terms, however, it would take forever to pump out the air in a larger vacuum chamber for larger batches. It will work fine for small chambers, and batches. This is a pretty good vacuum, especially considering it is coming from a hand pump. In this video, he states that the lowest pressure achieved was -27 inHg. When buying a vacuum sealer for vacuum purging you’ll want to look for one that has a hose attachment such as the FoodSaver V4440 or FoodSaver FM2435.Īnother entry level method is a hand pump made for bleeding brake lines, seen here demonstrated by a gentleman rebelling against shirts. This will absolutely help the quality of your BHO and is easily accessible. In this video below you can see that the lowest pressure that a food saver can achieve is -20 inHg. However, you’ll still need a vacuum chamber. These vacuum sealers are good for personal use, especially if you already have one in your kitchen. Vacuums for BHO Vacuum Purge Food Saver Vacuum Sealerįor entry-level vacuum purging bho, you can use a FoodSaver vacuum sealer. When vacuum purging dab you’ll need a vacuum, a vacuum chamber, and a silicone mat to keep you vacuum chamber clean. The quality of your vacuum purging equipment will determine how long you have to wait for good dab and how low of a temp you’ll be able to keep it. How to Vacuum Purge BHO: Vacuum Purging Equipment It is tough to get a true vacuum, really tough, but that is the goal we are heading for so how close can we get? Well, it depends on the equipment you’re using. When -29.92inHG is met, an absolute vacuum is created, devoid of all atmosphere. Our goal when purging BHO is to achieve a system as close to -29.92inHG as possible. This is the pressure you and I are experiencing this very moment, varying slightly based on altitude, relative to sea level. The term “inches of mercury” has its roots in old-school barometers, at 1 atmosphere the mercury in a barometer will move up to 29.92 inches in the tube. When you vacuum purge BHO, most vacuums will measure the atmospheric pressure in “inches of mercury”, most commonly denoted as inHB or “HB.
