8mm PTFE Septum, 100/pk

When you’re hard at work performing important sample preparation, the last thing you want is for your samples to become contaminated by some sort of external particulate contaminants. Luckily for you, we’re happy to provide a solution with our 8mm PTFE Septa for sample collection vials. At the most rudimentary level, a septum is used to seal the MS injection port and protect your sample from outside contamination. The septum forms a barrier between the analyte in your sample vial and the outside atmosphere. That way you can inject your sample without any added external contaminants. This septum is made out of PTFE material and is easy to puncture for sample injection, plus it comes in a pack of 100. That way you have enough septa to continue use across all your sample preparation applications. Upgrade your sample prep assays and protect your precious samples in the process when you purchase the 100-pack of 8mm PTFE Septa for sample collection vials. Don’t hesitate to ask your lab manager to add the 8mm PTFE Septum 100-pack to your lab’s procurement list when it’s time to stock up.

What does a septum do?
A septum is an integral part of sample preparation, as it’s responsible for keeping external contaminants out of your precious samples. What’s more, the septum allows a needle from a manual or automatic syringe to enter the vial without allowing any other contaminants from entering. This is hugely important when performing sample preparation, as any contaminants in samples could end up causing data variability and the need for unneeded reproducibility.

What about the caps for your sample collection vials?
The right vial cap is equally as important as the right septum, as it’s also responsible for preventing external contaminants from entering your samples. To properly cap your samples, we recommend purchasing this 100-pack of Black Screw Neck Caps. These caps are held to similar strict dimensional tolerances as your septa and vials.
