20mm Black Flip Top Caps by Chudeng – 100pcs Aluminum‑Plastic Caps

Description

Product Overview

The 20mm Black Flip Top Caps by Chudeng are engineered for precision laboratory environments where reliability and ease of use are paramount. Each cap combines a rigid aluminum base with a flexible plastic top, delivering a secure seal that resists corrosion and mechanical stress. The caps are supplied in a bulk pack of 100, ensuring that laboratories and research facilities have ample inventory to meet high‑throughput demands without frequent reordering.

Manufactured from a high‑grade aluminum‑plastic composite, these caps provide a balance of strength and lightweight handling. The aluminum component offers excellent barrier properties against moisture and gases, while the plastic portion is designed for a smooth, tactile flip‑top action that simplifies opening and closing procedures. This dual‑material construction also contributes to the caps’ ability to endure repeated sterilization cycles at elevated temperatures, making them suitable for rigorous cleaning protocols.</n

Designed specifically for 20mm glass vials, the caps feature a half‑tear mechanism. When the user removes the plastic cap, the aluminum base remains intact, preserving the integrity of the seal for subsequent uses. This feature reduces waste and enhances cost‑effectiveness, as the aluminum component can be reused multiple times while the plastic portion is easily replaced.

Chudeng, a reputable manufacturer in the laboratory supplies sector, ensures each batch meets strict quality standards. The caps are produced under controlled conditions, with thorough inspection for dimensional accuracy, material consistency, and functional performance. This commitment to quality guarantees that every cap delivers consistent performance across a wide range of applications, from routine sample storage to critical analytical procedures.

Usage

These caps are ideal for sealing 20mm glass vials used in chemical analysis, biological assays, and pharmaceutical research. Their flip‑top design allows quick access to the vial contents while maintaining a tight seal that prevents contamination and evaporation. Users can confidently store volatile solvents, sensitive reagents, or biological samples, knowing the caps will protect against external influences.

In high‑throughput laboratory settings, the ease of operation provided by the flip‑top mechanism reduces handling time and minimizes the risk of sample loss. Technicians can open and close vials rapidly, which is especially beneficial during repetitive tasks such as plate preparation, sample aliquoting, or routine inventory checks. The half‑tear feature further streamlines workflow by eliminating the need to replace the entire cap after each use.

These caps also perform well under sterilization conditions. Laboratories that employ autoclaving or dry heat sterilization can subject the caps to temperatures up to 180 °C without compromising their structural integrity. This capability ensures that the caps can be safely reused in sterile environments, supporting compliance with stringent biosafety protocols.

Beyond laboratory benches, the caps are suitable for field applications where portable sample storage is required. Their robust construction withstands transport shocks, while the flip‑top action provides convenient access in remote or mobile settings. Whether used in academic research, industrial quality control, or clinical diagnostics, the caps deliver consistent performance across diverse operational contexts.

FAQ

Can these caps be used with vials other than 20mm?

While the caps are optimized for 20mm glass vials, they can also fit other containers with a compatible 20mm thread size. However, for best sealing performance, we recommend using them with standard 20mm vials designed for laboratory use.

Are the caps sterile out of the package?

The caps are not pre‑sterilized, but they can be sterilized using high‑temperature methods such as autoclaving or dry heat. This allows users to apply the level of sterility required for their specific applications.

What is the half‑tear mechanism and how does it work?

The half‑tear mechanism means that when the plastic top is removed, the aluminum base remains attached to the vial. This design prevents the entire cap from being lost and enables the aluminum component to be reused, while the plastic portion can be replaced as needed.

How many times can the aluminum base be reused?

When handled according to the manufacturer’s guidelines and subjected to proper sterilization cycles, the aluminum base can be reused many times without loss of sealing integrity. Its lifespan largely depends on the frequency of use and the conditions of sterilization.

Is there a warranty on these caps?

Chudeng offers a limited warranty covering manufacturing defects for a period of 12 months from the date of purchase. If you encounter any quality issues, please contact our support team for assistance and replacement options.
