In HPLC analysis, the particle size of the chromatographic column packing is small and it is easy to be blocked by impurity particles. Therefore, samples and solvents need to be filtered in advance to remove particulate contaminants and protect the instrument. Ion chromatography, which is commonly used in environmental analysis, also requires that no inorganic pollutants be introduced in sample pretreatment. Syringe filters can be used in HPLC analysis and IC analysis to filter sample solutions, which is an important step in the sample pretreatment process.

8-425 Screw Cap  are universal. Screwing the cap applies a mechanical force that squeezes the septum between the glass rim and the cap. Screw caps form an excellent seal and mechanically hold the septum in place during piercing. No tools are required for assembly. The Screw Caps that are inlcuded with this kit are knurled on the sides for excellent gripping and comfort when applyting to the vial.

The cap is made of aluminum. Aluminum is commonly used due to its excellent sealing properties and resistance to corrosion. The septa is a critical component of the cap and is made of silicone or PTFE (polytetrafluoroethylene).  It is positioned inside the cap and serves as a barrier between the sample and the external environment. The cap has a crimp top design, which means it can be securely attached to the vial by using a crimping tool. This process involves crimping the cap around the vial’s neck, creating a tight and tamper-evident seal. These caps with septa provide an effective barrier against contamination, evaporation, and changes in sample composition, ensuring that the sample remains stable and reliable for analysis.

Headspace vials are a kind of laboratory vials for top space analysis, with the features of high-temperature resistance and corrosion resistance. A headspace vial is used in the process of top–gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial. The material of Headspace Vials is low extractable Borosilicate glass with a low expansion rate, high-temperature resistance, high strength, high hardness, high light transmittance, and high chemical stability. Headspace Vials are suitable for headspace analysis of volatile solids and gases.
