Eliminate Overtightening in Labs with StopIT Vials for Better Results

Why Do We Overtighten Vials?

Overtightening is a natural tendency, especially when you want to ensure a secure seal. In high-pressure lab environments, it’s easy to assume that “tighter is better.” However, standard screw top vials don’t provide clear feedback on when the cap is sealed, leading users to apply excessive force. This can result in:

• Crushed or damaged septa: Excessive pressure can deform or puncture the septa, which can lead to the septa being pushed into the vial or breaking the needle - leading to leaks or contamination.
• Thread damage: Overtightening can strip or wear down the vial threads, reducing their lifespan and reliability.
• Sample loss: Leaks caused by damaged seals can result in lost or compromised samples.
• Inconsistent results: Poor sealing can allow evaporation or contamination, affecting the accuracy of your analysis.

The Real Cost of a Simple Mistake

A single overtightened vial can disrupt an entire workflow. Lost samples mean lost time, wasted reagents, and potentially invalid results. In regulated environments, such mistakes can even lead to compliance issues or failed audits. Preventing overtightening isn’t just about convenience—it’s about protecting your data, your budget, and your reputation.

How StopIT Vials Solve the Problem

Chromatography Direct’s StopIT Vials are designed to eliminate overtightening—by design. Here’s how:

• Integral Glass StopIT Ring: Each vial features a specially engineered glass ring positioned just below the thread. When the cap is screwed on, it meets this ring, providing a clear, physical stop. This ensures the septa is perfectly sealed without the risk of overtightening.
• Consistent, Reliable Sealing: The StopIT Ring guarantees that every vial is sealed to the same specification, reducing variability and improving reproducibility in your results.
• Protects Septa and Threads: By preventing excessive force, StopIT Vials extend the life of both the septa and the vial threads, saving you money and reducing waste.
• Easy to Use: No guesswork, no special training—just screw the cap on until it stops. That’s it.

Make Overtightening a Thing of the Past

Lab work is challenging enough without worrying about leaks or damaged vials. With StopIT Vials, you can focus on your science, confident that your samples are secure and your results are reliable.
