Every company's cartridges are a little different, but most of them can be screwed apart at the mouthpiece, where you'll have access to the oil. Because of the oil's consistency, though, you'll probably need a syringe to effectively remove it and reapply it elsewhere.
how to take apart a disposable vape pen？
Tools:
X2 - Pointed tweezers
X1 - Pointed pliers
Warning: Some units are sealed into place and can be very hard to remove from housing. I got lucky with this one. I had one pen in the past that was impossible to get out no matter how much force. Used a steel rod againsta concrete floor and near full body weight and the capsul would not move either direction. Be careful not to hurt yourself if the unit is very stuck.

Why does my vape feel clogged?
This is one of the most common reasons you'll have to change your coil regularly, because the build-up around the coil interferes with the flavor of your e-juice and the gunk in your wick affects its ability to soak up e-juice. The gunk is essentially residue from e-liquid that hasn't been successfully vaporized.
The holes in the cartridge may be clogged with oil. Try warming your cartridge with a hair dryer (lowest heat setting) or by rubbing it between your hands to warm up the oil and change its viscosity. You can also poke a toothpick or safety pin gently in the hole to help de-clog it.
Assuming all vape pens from a particular manufacturer are excellent, here are few more factors that affect how durable your purchase will be.
Temperature control
Regulating the temperature will help start slow and fine-tune the pen, so it is not overheating at any point?
Battery life
The longevity of the battery is the longevity of the device. Once the battery dies and becomes weak for reusable pens, you just might have to get a new pen.
Ceramic or quartz coils
The type of heating element has everything to do with it being reliable, so you are sure it will not die on you. Ceramic coils seem to heat smooth clouds while quartz atomizers will draw large clouds. Find the best engine and find your longest lasting vape pen.
Ergonomic, durable body
Often a vape pen may be subjected to excessive mistreatment when you accidentally sit on it and such. For this reason, the organization ought to be sturdy and durable.
