Pre-slit PTFE/Silicone Septa is designed for applications where larger sample volumes need to be injected from a vial to avoid aspiration. This septa allows ambient gas to balance the gas in the vial, reducing the vacuum created by a tight seal around the needle. The pre-slit design makes the septa easier to penetrate with a needle and releases the vacuum created when removing large samples from the vial, while maintaining chromatographic properties similar to un-slit septa.

Chromatography septas can be pre-slit. A pre-slit septum is an ideal choice in applications requiring 20% or more of the sample injection each time from the vial so that suction is avoided. The slit allows ambient gas to equalize the gas in the vial so that a vacuum is not created in the vial from the tight seal around the needle. If coring or clogging from a narrow needle or needle deflection from highly durable septa material is a concern, then choosing a pre-slit septum is a better choice.
A PTFE/Silicone with a slitted septum allows for easier needle penetration as well as to release the vacuum that forms when a large volume of sample is withdrawn from a vial. This septum provides chromatographic characteristics similar to that of a septum without a slit except that the ability to withstand exposure to aggressive solvents is slightly lessened. Pre-slit septa are highly recommended for improving injection-to-injection reproducibility with autosamplers withdrawing greater than 50µL of sample from a 2mL vial, due to possible cavitation (vacuum).

Material is Brosilicate Glass/1st hydrolytic class glass. 100pcs packed in one box. Available in clear and amber.

Borosilicate glass is chosen because it is resistant to chemical reactions and can withstand high temperatures, making it ideal for containing volatile samples without contamination. 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.

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.

11mm Crimp Top Autosampler Vial for GC and HPLC. Vials have a 40% larger opening than standard opening aluminum seal vials, manufactured of Clear or Amber borosilicate glass. The standard 12x32mm profile is compatible with 11mm aluminum seal closures. The precision-shaped bottleneck can improve the processing capacity of the autosampler. In order to ensure good function, it can be slit in advance to facilitate needle penetration, designed for single injection or short sampling cycle, and especially suitable for liquid chromatography. 

The slit allows ambient gas to equalize the gas in the vial so that a vacuum is not created in the vial from the tight seal around the needle.
If coring or clogging from a narrow needle or needle deflection from highly durable septa material is a concern, then choosing a pre-slit septum is a better choice.
A PTFE/Silicone with a slitted septum allows for easier needle penetration as well as to release of the vacuum that forms when a large volume of sample is withdrawn from a vial.

Fused-insert sample vials work with both snap caps and crimp caps. These small samples fused-insert vials work with both snap caps and crimp caps. 11mm Glass Crimp Neck Vials with Fused Inserts are ideal for handling small-volume samples while delivering low residual volume. 11mm Glass Crimp Neck Vials with Fused Inserts offers the simplicity and functionality of typical micro vials at a fraction of the cost. 0.3 ml clear glass micro insert fixed in 2 ml glass vial. Bottom fixed micro insert to keep the vial central vertical. Vials with integrated Micro-Insert are also available now in clear and amber glass. amber glass makes it compatible with sun-proof samples. Their glass Micro-Insert is absolutely centered in the plastic mold and pressed firmly against the septa due to its slightly exceeding edges.

There is one type of Vial produced by Aijiren that has the best sealing performance, that is, 20mm Headspace Crimp Vial, but it coexists with the tight sealing characteristics of Crimp Neck Vial and there is also the problem of how to seal it. Aijiren provides a 20mm Hand Crimper and Decrimper to match the Crimp Vial. Aijiren’s handheld crimping machine provides a consistent and reliable seal, ensuring that the vial is securely sealed every time. The high-quality structure has been carefully designed, has durability and long life, and can provide smooth and simple operation. Manually adjustable stop, comfortable to hold the cushion, economical and durable.
