Gansulin Pen with Case

The reusable Gansulin pen is a rugged, all-metal delivery device built for repeatable, low-volume research workflows. The spring-loaded mechanism gives you smooth, low-force delivery every time, taking the guesswork and effort out of repeat use. The housing is solid metal, not plastic, so it holds up to daily handling far better than a disposable alternative. Designed around the 3 mL (300 unit) cartridge format, it offers a 1 to 60 unit dial range in 1-unit increments for consistent, fine-grained control. A mechanical dial provides clear tactile and audible feedback on every setting, so you always know exactly where your volume is set before delivery. It's compatible with our EasyTouch pen needles. Because the cartridge is replaceable while the pen body is reused, this is a more economical option over time than single-use disposable pens, without giving up build quality or accuracy.
