3ml 5x4 open holder

This 3D-printed holder is designed to safely and efficiently store 20 vials (5 rows of 4) of 3ml peptides in a refrigerator. The open design ensures easy access and visibility of the vials. Made from a durable, fridge-safe plastic material, it maintains structural integrity at low temperatures, preventing warping or cracking. The compact 5x4 configuration maximizes space utilization, making it ideal for crowded refrigerators. Each slot securely holds a 3ml vial, preventing accidental spills and keeping the peptides organized. The open top allows for quick identification and retrieval of specific peptides, streamlining laboratory or research workflows.
