20mm Flip Off Caps LabZhang Blue Plastic Aluminum Vial Seals 100pcs

Description

Product Overview

The 20mm Flip Off Caps from LabZhang are engineered to meet the rigorous demands of pharmaceutical and laboratory environments. Constructed from a high‑grade plastic‑aluminum composite, each cap delivers a balance of flexibility and strength that protects the integrity of glass vials while allowing effortless removal when required. The caps feature a full‑tear design: once the outer plastic layer is removed, the underlying aluminum seal is permanently exposed, providing a tamper‑evident indicator that the vial has been accessed. Finished in a vibrant blue hue, the caps are easy to identify among a range of laboratory supplies, reducing the risk of cross‑contamination and streamlining inventory management. Each cap measures precisely 20mm in diameter, conforming to standard vial threads, and the package includes 100 caps, ensuring sufficient stock for routine testing, batch production, and emergency reserves.

Usage

These caps are ideally suited for a variety of applications where a secure, sterile seal is paramount. In pharmaceutical manufacturing, they protect active ingredients from moisture, oxygen, and accidental exposure, preserving potency and extending shelf life. In research laboratories, the caps are used on sample vials for analytical chemistry, microbiology, and biochemistry assays, where maintaining sample integrity is critical for reproducible results. The blue coloration assists technicians in quickly locating the correct caps during high‑throughput workflows, while the flip‑off mechanism enables rapid opening without the need for specialized tools, reducing handling time and minimizing the risk of sample loss. The caps are also compatible with standard vial racks, centrifuges, and automated filling equipment, making them a versatile choice for both manual and automated processes.

FAQ

What types of vials are compatible with these caps?

The caps are designed for standard 20mm diameter glass vials commonly used in pharmaceutical and laboratory applications. They fit both screw‑threaded and snap‑fit vials that adhere to the 20mm specification.

Can the caps be reused after the plastic layer is removed?

No. The caps employ a full‑tear mechanism; once the outer plastic layer is torn away, the underlying aluminum seal is permanently exposed and cannot be resealed. This feature provides a clear indication that the vial has been opened.

Are the caps suitable for sterile environments?

Yes. The caps are manufactured under cleanroom conditions and are packaged in sealed, sterile‑grade bags to maintain sterility until use.

How should the caps be stored to maintain their quality?

Store the caps in a cool, dry place away from direct sunlight. Keep them in their original packaging until needed to protect the plastic surface from dust and moisture.

What is the recommended torque for sealing the caps?

Apply a firm but gentle hand pressure until the cap clicks into place. Excessive force is not required due to the snap‑fit design, which ensures a secure seal without over‑tightening.

LabZhang’s 20mm Flip Off Caps represent a thoughtful blend of material science, ergonomic design, and regulatory compliance. Whether you are securing a batch of vaccine vials, preserving a series of research samples, or managing inventory in a high‑throughput laboratory, these caps deliver the reliability and performance needed to maintain product integrity and operational efficiency. By investing in a pack of 100 caps, you secure a consistent supply that aligns with your workflow demands, reduces downtime, and supports the stringent quality standards expected in modern scientific and pharmaceutical settings.
