Similarly, you can interchange LTX 12 Bottles among Purell, Provon, and GoJo brands by swaping the RFID sensor. I have not tried pulling it off as shown in this video but it sure looks simple. Less risky, you can simply cut a small plastic nib with any side cutters and remove the whole collar from each bottle. Swap the collars and the bottles are interchangable without taking the base apart as shown in this video. If you want to refill the empty 40 ounce bottle from any LTX 12 foaming dispenser just drill a 1/4 Inch hole in the top of the 40 ounce bottle, mix up the following solution , and add with a clean mustard like bottle. Clean and Tape over that 1/4 inch hole with black electrical tape so your home made solution below does not evaporate. All of the ingredients can be bought online. Hand sanitizer can be hard to fine in these Pandemic times. Don't waste your money on expensive refills that are hard to find and don't do without. 12 Ounces of 100% Aloe Vera Gell 24 Ounces of Iso Rubbing Alcohol (70 or 90%) 1.5 Ounce of Cocamidopropyl Betane (Surfactant for Foaming) 1/2 Eye dropper of Lavender Essential Oil
The native firmware will only allow up to three refills worth of dispenses to occur before the RFID chip is blacklisted and will no longer allow dispenses.
Very interesting! I wonder if that will also be the case with LTX 12 dispensors which the manufacturer never dreamed anyone would refill as mentioned by me above. The method is simple so savings from the first 3 cheap refills make it worth it. Buy a new one and fill it 3 more times if the RFID fails to work. Only time will tell. Sounds like the RFID sensor counts the number of dispenses and this is set to 3X the expected number. There can be no blacklist as you mention since this is not an online device nor is there any shelf life on the bottles.
@@donh6009 perhaps he means locally on that board only. In my case I have multiple units so can move a "blacklisted" chip to a different unit and go for awhile.
I tried to do that, it didn't work for me. Theres a coil around the little cartridge that is reading the radio chip and transmitting to the circuit board that info from what I saw.

I can’t wait to try this on ALL my GOJOS

Thats interesting, haven't heard that yet or had it happen. And here I thought it was a permanent solution. Will have to wait and see.

Also the 1/8" TRRS jack on the device allows for UART communication, you can get the refill serial number, battery status and a few other goodies.
This was super helpful. Thank you!
wow - good trick!
💯
Can you not just glue it in place then take the sensor off of the replacement one and install?
yeah for sure, you can swap chips but the next time its change you have to make sure it has the right chip in it or the old chip is out.
Could you just use a jumper wire on the plug into that sensor to do the same thing?
I was thinking the same thing. Would be nice to know
I tried to do that, it didn't work for me. Theres a coil around the little cartridge that is reading the radio chip and transmitting to the circuit board that info from what I saw.
or just buy th epurell branded one
For sure, that's what I'd do today but this was a year ago when you couldn't get any of those.
@@racer3822 what do u use now
Lol didn’t know you are trying to be a RUclipsr
Not really but i tried to find info on it online and found nothing so figured id put out there what I learned. Didn't take anytime to record.
