Yes luckyscent samples come in dab vials.
I've done this several times as I find spraying to be the only proper way of testing a perfume. Dabbing is just not the same. I usually order 2 or 3 samples of each perfume which gives me about 1.3ml or 2ml in the atomizer since you're bound to loose a portion while transferring.
1 ml is approx 10 sprays. The amount of sprays will vary from 7 to 12 depending on the sprayer on your atomizer but an 1ml is approx ~10 sprays.
