1.Which vial is best for my sample size?
There are several factors to consider, including analysis type, analytical platform, and sample availability.
NEWSTAR vials offer the same highly consistent performance across the entire size range, from 150 μL up to 60 ml.
2. How do vial components factor in?
Vial caps, septa, and inserts prevent leakage and sample loss due to evaporation. Like NEWSTAR vials, NEWSTAR vial components receive the same high level of attention during design and manufacture. They also work seamlessly with NEWSTAR vials so complex runs proceed smoothly.
3.How do I choose the right closure?
There are three major factors to consider when selecting a closure.
1.Compatibility of septa and sample
2.Compatibility of septa and cap
3.Crimp cap vs. screw cap
4.Are the septa chemically compatible with your samples and solvents?
NEWSTAR provides this septa compatibility as a guide and starting reference point. We realized that chemical compatibility can vary depending on the concentration of the solvent, temperature, molecular weight of the solvent,and other factors. Therefore it is always recommended you to try a variety of septa to determine the best one for analysis.
5. What's the difference between crimp cap and screw cap?
Crimp-cap vials tend to be best for GC and GC/MS applications, while screw-cap vials are generally used for LC and LC/MS applications. However, your specific application—as well as your personal preference— are also factors to consider. Although both types of caps deliver a good seal, crimp caps provide additional security for food, forensics, and other applications for which you want to avoid sample tampering. We also recommend a crimp-cap vial if you are working with volatile compounds.
