Just ordered these. The numbers are a little hard to read but they work fine and graduation is not as finite as the plastic syringes. There slip lock but lour lock needles fit fine.

Plastic also work fine and I order those by the 100 on ebay. They wash up fine but as expected wear out after 20 - 30 uses. Dipping the plunger in VG before use can help this.

Regarding plastic syringes, they are washable and plain hot tap water will do the trick for nic base, PG, and VG. For flavorings, I suppose it depends just how meticulous and precise you want to be. A hot water rinse between flavors probably removes at least 99% of the old flavor, but if you are a perfectionist, or just don't want to deal with rinsing during your mixing process, separate ones for each flavor might be what you want.

Regarding the needles, most of what comes in contact with your fluids is metal, so I would be even less worried about "cross contamination" with a quick rinse, and perhaps wipe down the outside with a paper towel and blow out any water from the inside before moving to the next flavor.

You can reuse the disposable plastic syringes and needles many times, but the markings may come off the syringes from washing. Clear tape or clear nail polish on the outside will preserve the markings. I am biased against nail polish so it is tape for me, but others use it with no apparent problems. Danny's recommendation for dipping the rubber part of the plunger in VG is also good.

Danny, have you used those glass syringes yet? If so, what do you think of them? As you know, certain liquids destroy plastic syringes quickly. :)

I just used it last night but it's to early to tell if they will hold up. I suspect they will. The markings are a bit more difficult to see then the plastic ones making them not as accurate for minute measurements such as .5ml. So far that would be my only negative with them.
