Keep your 3ml vials secure and organized with 12 Pack Vial Caps—leak-proof, dust-resistant silicone covers designed to protect opened injection vials and reduce waste.
Each cap is made of flexible silicone that fits snugly on 3ml glass vial necks, creating an airtight seal that stops leakage and evaporation. They're also reusable: rinse with warm soap and water, air dry.
The set includes 12 caps in 6 bright colors (2 per color: red, blue, green, yellow, purple, orange)—ideal for color-coding different vial contents.
Designed specifically for 3ml vials, these caps fit most standard 3ml glass injection bottles and work with 3ml vial holders for neat storage. They're easy to use: just stretch the cap over the vial neck, and it stays in place until you're ready to remove it. No tools, no mess—just reliable protection for your valuable liquids.
Whether you're a researcher, healthcare professional, or DIY enthusiast, 3ml Vial Caps combine functionality, durability, and organization. They're the simple solution to keeping your vials clean, secure, and easy to manage—every time.
