A peer-reviewed article by researchers at the University of Shanghai for Science and Technology (USST), published in an international biomedical engineering journal, reports that the Hextra Tech™ hexagonal, broad-platform hub used in Sandstone Easydrip™ Plus pen needles improves injection stability and user comfort versus conventional narrow hubs in laboratory bench tests. The study measured lower needle deformation and higher anti-tilt resistance under load, attributes that help keep the needle closer to perpendicular for more consistent subcutaneous delivery. These engineering findings are consistent with the product's human-factors design rationale.

"For people who inject daily, a pen needle that stays steady and feels gentle can reduce anxiety and support adherence," said a Sandstone spokesperson. "Hextra Tech™ was engineered to give users greater control at home and on the go."

What sets Easydrip™ Plus apart

Hextra Tech™ hub stabilization — Broad, six-facet platform that steadies the pen during insertion, helping reduce wobble and the risk of bending/breakage in self-injection.

Controlled penetration path — Geometry tuned to support perpendicular entry and help avoid intramuscular delivery, reinforcing reliable at-home dosing.

Enlarged inner & outer caps — Easy-grip, ergonomic caps designed for secure handling and single-hand re-capping while helping guard against accidental sticks.

Smooth insertion — Thin-wall, polished multi-facet cannula with silicone lubrication supports gentle, low-force entry and dependable flow.

Practical range — Single-use, sterilized; available in multiple gauges and lengths; compatible with widely used insulin pens.

Pen-needle stability and comfort directly influence user confidence and adherence. A hub that resists tilt can minimize off-target delivery and help make frequent self-injections feel more manageable—outcomes Easydrip™ Plus is designed to support.
