Tonight is the night to CBT. I have finally received all of the components needed to construct the GULPS CO generator. You can find most of these in one place online. Here is what you will need:
1. Large/small jar with outgoing tube
2. Washing chamber with incoming tube
3. Cardboard lid with incoming/outgoing hose attached
4. Set up resting in carrying container
- Sulfuric Acid
- Need at minimum 98% purity.
- I found a supplier that sold 950ml for approximately $35.
- Formic Acid
- Need at minimum 85% purity.
- I found a supplier that sold 950ml at 96% purity for about $35.
- Large Glass Jar
- The jar I found is 3.50 x 3.50 x 6.40 Inches (LWH)
- Found one for about $3.
- Small Glass Jar
- Finding one was a huge problem as some were too wide, too tall and too small.
- I did find one that fits perfectly... a normal shot glass.
- I had one already, but found you can get a set of 6 for about $7.
- Tubing
- At first I found a 6mm 16 foot tube. It was waaaay to flimsy and had too many kinks for it to work.
- I then found a sturdier plumbing tube. 6mm, 32 feet.
- It even came with a tube cutter and some fittings.
- I cut the tube and used about 24 inches.
- 5 liter container (washing chamber).
- I used a Zerowater filter container.
- Incidentals - what I used
- Duct tape
- Scissors
- Sharp knife
- Sharpie
- Cardboard
- Large carrying container to hold everything
- Water
- Screwdriver
- Hammer
- CPaP mask
- CPaP hose
- Cut the tubing and use about 24 - 36 inches.
- I used a screwdriver and hammer to puncture a hole in the lid of the large glass jar.
- I Used the screwdriver to widen the hole for the fitting and tube.
- I used the small fitting to secure the tube
- I then used duct tape to secure the tube and fitting to the lid.
- You don't need to do anything special with the small glass jar.
- Thoroughly clean the Washing Chamber.
- Grab some cardboard, and traced the lid with the Sharpie.
- Used the shard knife to puncture where the holes are going to be.
- Used scissors to cut the hole for the outgoing hose (CPaP hose).
- Made a notch in the cardboard for the small incoming hose (see pics)
- I taped the incoming tube to the inner part of the chamber, and then taped the end of the tube so it sits in the middle of the bottom ensuring the gas will have space to get to the water.
- Use the duct tape to secure the outgoing hose (CPaP hose) to seal any gaps.
- Use the duct tape to secure the lid to the container.
- Leave about 1/5 un-taped to add the water later.
- Attach the CPaP hose to the CPaP mask.
- What you should have by now
- Small glass jar inserted into the large glass jar
- Tubing attached to the lid.
- Do not have the tube inserted all the way. Just enough to capture the gas.
- You don't want the acid to dissolve the tube
- Do not have the tube inserted all the way. Just enough to capture the gas.
- Cardboard lid cut and tubing attached and secured.
- Lid mostly secured with duct tape.
- Now when you're ready to CBT this is what you do
- Fill the washing chamber half full of water. I used purified water
- Secure the rest of the cardboard lid
- Put the washing chamber into the carrying container
- Take the small jar out of the large jar
- USE CAUTION HERE.Yes, we are CBT'ing, but still be careful. These are very caustic chemicals.
- Carefully add 250ml sulfuric acid to the large glass jar
- Set aside and make sure it's not going to spill
- Carefully add 50ml formic acid to the small glass jar
- CAREFULLY place the small glass jar inside the large glass jar
- DO NOT SPLASH or mix the chemicals.
- Secure the lid to the large jar.
- When you are ready to CBT then tip the large jar and ensure the two acids mix
- This is what's going to produce the CO
- When you start seeing bubbles in the washing chamber you can put the mask on.
- CBT in about 2 minutes, if you did everything correctly.
- Carefully add 250ml sulfuric acid to the large glass jar
1. Large/small jar with outgoing tube
2. Washing chamber with incoming tube
3. Cardboard lid with incoming/outgoing hose attached
4. Set up resting in carrying container
