Thanks.
And does a 510 tip fit on the top of the sophia?
Not the long body. That one has an integral drip tip.
Note also that for the standard length Sophia, while regular 510 drip tips will (mostly) fit, I have found that it can be difficult to adjust the juice flow if trying to spin the tube by holding on to the drip tip - the drip tip just spins, and not the tube itself. Not a huge deal, you can just adjust the juice flow by holding on to the Sophia itself, not the drip tip.
I think this happens because most standard drip tips only have one small o-ring at the base, as compared to the double o-rings on the base of the By Leo drip tips.
Here is a pic from ByLeo of the ST drip tips (5, 10, 15 and 20 lengths) - note the double o-rings on the bottom:
As compared to regular 510 drip tips, which usually just have one o-ring:
