精密滴管

I've been using this for my titration work and the clear glass makes it so easy to watch the fluid level drop without squinting. The tip delivers a steady, controlled flow, which cut my measurement errors way down.

The precise tip gives me way more control than my old glass one—no more overshooting the mark when I’m doing titrations. It’s sturdy enough for daily lab work, and the fluid level is always easy to keep an eye on.

The clear tube makes tracking the meniscus stupidly easy, even under harsh lab lighting. I’ve used it for titrations all week and the flow stops exactly when I want it to, no drips or hesitation.
