1) Description
Snap top vials and snap caps are a sample containment solution for nonvolatile liquid samples.
No crimpers, decappers, or other tools are required when using snap top vials. Snap top vials enable the user to hold both the pipette and snap cap in one hand and the snap cap vial in the other when pipetting, making them more convenient than other vial types. 11 mm snap cap vials are compatible with standard 11 mm snap caps with an 11 mm internal diameter. Snap caps come with a variety of septum combinations including PTFE/silicone, solid polyethylene, polyurethane, and polyethylene olefin.
Snap top vials are recommended for use with nonvolatile matrices that do not require an extra-secure seal. They are often used for HPLC, in pharmaceuticals, biopharmaceuticals (deactivated glass options), and other associated market segments.
2) Features
▶ The vials are used on instruments of Agilent, CTC, Thermo Scientific, Waters, etc.
▶ Snap Ring finish eliminates the need for crimping or decapping.
▶ Snap-top sample vials are available with optional ceramic writing markers.
▶ The integrated Micro-insert are available for in clear and amber glass, micro-inserts can be delivered pre-assembled in vials.
▶ Snap ring caps are also available in soft material with transparent or blue caps, soft caps are more convenient in handing (push on/off.
▶ The septa shapes have pre-slit and snow-shape types to choose.
▶ Unique packaging design reduces vial breakage.
▶ Uniform flat bottom ensures compatibility with a variety of vial inserts.
▶ Marked with 0.5, 1.0 and 1.5 mL graduations to help visualize sample volume.
3) Application
Gas Chromatography (GC): Used to store and transport samples of gases or volatile organic compounds. In GC analysis, the sample needs to volatilize at high temperature, so there are high requirements for the sealing of the vial.
Liquid Chromatography (LC): In particular, High Performance Liquid Chromatography (HPLC) analysis is used to store liquid samples. The 9-425 vial is designed for use with autosamplers, allowing for accurate and rapid injection of samples into the column.
Sample Preservation: This vial is also commonly used to preserve chemicals, biological samples, or other sensitive materials for long periods of time, especially samples that need to be preserved under specific conditions.
