Product Description
The LZHNB 3 Milliliter Pen Cartridges are engineered for users who require precision and safety in their research or personal care routines. Each cartridge is crafted from high-quality, non-reactive borosilicate glass, ensuring that your contents remain stable and uncontaminated. These cartridges feature a specialized 11mm long stopper design, making them perfectly compatible with V1 and V2 reusable injection pen systems.

The transparency of the glass allows for easy monitoring of levels, while the sturdy construction resists thermal shock and chemical reactions, maintaining the integrity of the stored liquid throughout its use.
