The only disposable multi-injection autoinjector for 3ml cartridges. The Haselmeier disposable Penlet is a fully automated multi-dose, fixed dose injection device designed for use with a standard 3ml cartridge. The Penlet features Haselmeier’s hidden needle design which hides the needle from the patient before and during injection. Pressing the clip on the pen causes the needle to automatically enter the subcutaneous tissue, followed by delivery of the preset volume of the solution.


The Penlet incorporates the following features:

Multiple fixed dose injections

Hidden needle to overcome the fear of injection

Automatic needle insertion and injection to facilitate handling for people with reduced dexterity

Easy to use and no dose adjustment required

Economical product with a cost per dose that may be less than a prefilled syringe
