In hydrology, capillary action describes the attraction of water molecules to soil particles. Capillary action is responsible for moving groundwater from ...

The search is over. If you work as a health care professional anyways.
I use the the spongey part of the oral swabs used to clean the mouths of patients as my plug for the cart. Just cut it a couple mm bigger than your cart opening and about 3/16ths of an inch thick. Then take a tube used to draw blood from the heels of newborns. This tube is hollow and uses capillary action to draw fluids upwards against the force of gravity.
Cut the tube at an angle like the end of a syringe needle. Make it about an 1/8th of an inch shorter than the cart. drip in your juice, plug it with the sponge. The tube pumps the juice into the sponge untill the sponge is full, then it stops. When the sponge begins to dry, it is refilled by the tube. Perfection at it's ultimate.

nice find.... wish i could try this. The e-juice is too thick for the needles that I have.

No needle needed my friend. Though I have found that syringes don't like e juice. After a use or two they get stuck. So much so that the rubber piece pulls out of the stick thingy. If you rinse it with water you can get about half a dozen uses before it is ruined. Good thing their free. For me anyways. Take care and remember.

Great idea, you should post pics or at least links so we can find what you are using and then we can test it.

You might need to try a different brand of syringe.

I have two here going on 2 months use that have never been rinsed or cleaned and both work fine.

A 3 ml syringe has never stuck, and a 10 ml has always stuck (since new) but a quick draw-back releases it for a smooth "injection" into the cartridge. Neither show any signs of separation or degradation.

those tubes contain heparin don't they.. might not be to good to be inhaling, the heparin is safe to inject as long as you do not have problems with bleeding the FDA warning is about that bad batch that went out when china tried to make it cheaper and killed a bunch of ppl..

 

[sjohnson]

No heparin is present in standard syringes or needles. There are too many medications where heparin is contraindicated to make it a standard, doing so would lead to medical errors.

not in syringes in the tubes for collection of blood. i am assuming that he was referring to the very thin 2-3 inch tubes that you can put up to a pin ..... and it sucks the blood up

 

[sjohnson]

OIC, I was referring to hypodermic syringes and needles just above your post so thought that was your point.

I'm thinking the poster confused evacuation collection tubes with the capillary pipettes used to draw blood from the heel of infants. Some capillary pipettes are heparinized and some are not, so I guess it would be best to find those that are not, as you stated.

I just love how for years we have inhaled over 4,000 different chemicals, many of them proven to cause cancer, and now all of a sudden everyone is concerned about what we put into our lungs.. I have moved on from the itty bitty tubes. The sponge I used seemed to hold onto to much juice and the tubes could not handle thicker (VG) liquid. If their is any heparin in the tubes by the time you cut it to about 1/2" down from from 4" the amount there wouldn't hurt a hemophiliac parakeet. The best mod I have found for the 4xx PV is Scottyballs's spring with blue foam. I was a bit tipsy and feeling very cocky when I started this thread. I did not fully test this method at the time of the initial post. I would suggest some Moderator delete this thread please. This method of modification is innefficient.
