  • 【Adequate Quantity, Universal Design】: Comes with 12 vial caps compatible with both 2ml and 3ml specifications, including 6 different colors (2 of each color). The caps are professionally designed to fit 13mm diameter bottle openings, matching 2ml and 3ml glass bottles. They can be used with proper sizing, offering high versatility. These bottle caps are specifically designed for peptide liquids and similar solutions, effectively storing opened remaining liquids or powders.
  • [For quick identification and classification]: These vial caps come in 6 bright and eye-catching colors, making bottle management more efficient. Each colored cap can correspond to different items or usage needs - whether sorting by liquid expiration date, type, or priority marking, it can be easily achieved. With color coding, you can quickly identify the liquids in different bottles, saving the trouble of searching and distinguishing while avoiding confusion. This is especially useful in scenarios where multiple bottles are used simultaneously, improving organization and usage efficiency.
  • [Dust-proof and Leak-proof, Sealed Protection]: These vial caps are made of soft materials with precise fitting design, forming a secure seal when tightly fastened on 3ml glass bottles. They effectively prevent external dust from entering, stop liquid evaporation inside the bottle, and maintain the original characteristics of the liquid. Moreover, these bottle caps can be washed with clean water, dried, and reused, ensuring cleanliness and hygiene. They significantly extend the shelf life of liquids inside the bottle, providing reliable protection and reducing waste.
  • [Easy to Clean and Maintain]: These vial caps are made of high-strength, durable materials. Compared to regular caps, they are more sturdy, wear-resistant, and less prone to damage and deformation. The caps feature a one-touch installation design, allowing for easy one-handed opening and closing, making them convenient for frequent use. They can be quickly cleaned after each use simply by rinsing with water, facilitating repeated use - perfectly balancing practicality and cost-effectiveness.
  • 【Versatile and Widely Applicable】Designed specifically for 13mm diameter bottles (including 2ml empty bottles and 3ml sterile bottles), suitable for storing and managing various media. These vial caps are not only ideal for household daily storage of insulin, peptide solutions, DIY essential oils, model paints, etc., but also meet the needs of professional settings such as hospitals, laboratories, clinics, and research institutions. Easily handle the storage of tinctures, essential oils, pharmaceuticals, cosmetics, and more, with strong adaptability.
