Automated self-injections without fear


The Pentek™ product platform is a disposable auto-injector and makes self-injection particularly easy. The hidden-needle design is particularly helpful for patients with a fear of injections, while automatic needle insertion and injection supports patients with reduced dexterity.

The Pentek™ product platform can be used for a range of applications, including various low-molecular-weight heparin.
