Description

Product Overview

Our 100-piece set of black plastic caps is engineered to meet the demanding needs of both home users and professional laboratories. Each cap measures precisely 38 mm in diameter and 16.6 mm in height, a size that aligns perfectly with standard 4 oz, 8 oz, 12 oz, 16 oz, and 32 oz containers. The caps are manufactured from high‑grade, food‑safe polypropylene that combines durability with a lightweight feel, ensuring that they can be handled effortlessly while still providing a robust barrier against leaks and contamination.

The design incorporates a tamper‑proof seal that visually indicates whether a bottle has been opened, adding an extra layer of security for beverages, chemicals, or any liquid that requires controlled access. The black coloration not only offers a sleek, professional appearance but also helps to protect the contents from light exposure, which can be critical for certain sensitive liquids. With a total package weight of just 15.2 ounces, the caps are easy to transport and store, making them an ideal choice for bulk purchases, inventory replenishment, or on‑site projects.

Usage

These caps excel in a variety of environments. In a laboratory setting, they provide a reliable seal for reagents, solvents, and sample containers, ensuring that volatile compounds remain contained and that cross‑contamination is minimized. For everyday consumers, the caps are perfect for sealing homemade juices, flavored waters, and carbonated drinks, allowing you to preserve freshness and carbonation for longer periods. Their universal 38 mm fit means they can be used on a wide range of bottle types, from glass to PET, making them a versatile accessory for both personal and commercial applications.

DIY enthusiasts will appreciate the caps’ adaptability for craft projects such as creating custom bottle lights, decorative containers, or even small-scale hydroponic systems. Because the caps are lightweight and easy to manipulate, they can be incorporated into educational kits, science fair projects, and art installations without adding unnecessary bulk. Whether you are a teacher preparing a chemistry demonstration, a hobbyist building a home brewing setup, or a professional lab manager maintaining strict inventory control, these caps deliver consistent performance.
