Scientific supply needles in the following tip styles: • Cone (tapered tip) – these are the most versatile needle for autosampler use and resist coring of vial and inlet septa • Bevel (sharp tip) instrument refer to Table 3.– these are typically used for manual injections. The tip shape helps reduce septa coring

Choose the right septa for your analysis. Although a wide variety of septa is available, chemical compatibility and temperature are the most critical to the analysis. Temperature applies not only to the vial, but also to the temperature of the instrument’s needle used for pressurization and sample. Compare this item.

Stoppers, also known as bungs, are used to give an airtight seal to laboratory flasks and test tubes by fitting tightly inside the neck of the container and preventing material from spilling. Stoppers can be made of glass, cork, rubber, or silicone. They are typically designed with a conical shape, but straight, flanged, and tapered options are
