How to Purge BHO Without a Vacuum: A Beginner’s Guide

What’s more exciting than striking gold?  Well, for a cannabis enthusiast, it’s striking oil – Butane Hash Oil (BHO).  But how do you purify this treasure, especially when you’re on a budget, and a vacuum purge isn’t an option?  Gather ’round, extraction enthusiasts, and let’s purge the mystery away!

How to Purge BHO Without a Vacuum: A Beginner’s Guide

Understanding Butane Hash Oil (BHO)

Understanding Butane Hash Oil (BHO)

BHO, as the cool kids call it, is a concentrated cannabis extract that packs quite a punch. 

It’s like the genie in the lamp – just a tiny dab, and you’re flying high. 

However, getting your BHO ready for a joyride requires extraction and purging, a process akin to refining crude oil into gasoline. 

But don’t worry; no need for a Ph.D. in chemical engineering. 

We’ll make this as easy as rolling a joint.

Purging Methods and Techniques

Ah, purging! Sounds a bit like something you’d do after a midnight fast food binge, doesn’t it? 

But in our case, it’s a method to remove residual butane and impurities from our cannabis concentrate. 

After all, you wouldn’t want a side of butane with your high. 

Without a vacuum, this task might seem daunting but fret not; we have a few tricks up our sleeve.

Brake Bleeding Sets, Hand Pumps, and Electric Pumps

You heard that right – brake bleeding sets

It sounds a little Mad Max, but it gets the job done. 

Thanks to the hand pump, these sets can act as a mini vacuum purge. 

It’s a bit of elbow grease, but on the bright side, think of the workout! 

Electric pumps can also serve the same purpose if you’re not into manual labor.

Toaster Oven, Warm Water Bath, and Other Techniques

For those of you who aren’t into the Fast and Furious garage vibe, don’t worry. 

We have some kitchen-based solutions too. 

A toaster oven set at a low temperature can help evaporate residual butane. 

Similarly, a warm water bath for your concentrate can do the job. 

Remember, butane is flammable, so don’t cook a grilled cheese sandwich in the oven while purging your BHO.

Temperature Range for Purging BHO

Temperature Range for Purging BHO

Speaking of heat, let’s discuss the temperature range for purging BHO

It’s crucial to maintain a safe temperature during purging. 

Aim for somewhere between 110-150°F (43-65°C). 

Go too high, and you risk losing those precious terpenes and cannabinoids. 

Go too low, and you might be left with some unwanted butane.

Equipment and Tools

While we’re playing MacGyver with brake bleeders and toaster ovens, you might need a few more tools. 

An Extractor Tube (honey bee extractor or stainless steel pipes with different inside diameters) and a Purging Container (like a glass dish or silicone mat) are necessary. 

The extractor is for blasting butane through your cannabis, and the purging container is where you’ll do the, you guessed it, purging.

Personal Anecdotes and Humor

So, this one time, when I was purging BHO, and I accidentally used my roommate’s favorite toaster oven. 

Let’s say there’s a reason why they call it “toast.” 

Always double-check whose appliances you’re using, folks!

Additional Information

While we’re all here for a good time, let’s also be here for a long time. 

For edible use, remember to decarboxylate your oil (activate the THC with heat) and perhaps winterize it, too (remove extra waxes and fats).

Benefits of Vacuum Purging

Vacuum purging – sounds fancy, huh? 

And while it is indeed the gold standard for purging, removing every last trace of butane, and retaining that delicious flavor, it’s not always necessary. 

Especially if you’re working with small personal batches

However, a vacuum purge might be a worthy investment if you’re considering going pro.



Purging BHO without a vacuum is like making a martini without a cocktail shaker. 

It’s a little tricky but perfectly doable. 

Maintain the right temperature, use the right equipment, and, most importantly, stay safe

You’re not just making BHO; you’re creating a masterpiece. 

Remember, every artist has a story to tell, so make yours a good one!
