The 20mm 20ml Crimp Top Headspace vial has a 20mm outer diameter, which is the standard size for crimp-style headspace vials. The 20ml capacity refers to the volume of the vial, meaning it can hold up to 20 milliliters of liquid or gas sample. These vials are typically made from high-quality borosilicate glass. 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.

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allows for easier needle penetration as well as to release of the vacuum that forms when a large volume of sample is withdrawn from a vial.

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allows for easier needle penetration as well as to release the vacuum that forms when a large volume of sample is withdrawn from a vial.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).

The 9mm Short Thread Caps that are included with this kit are knurled on the sides for excellent gripping and comfort when applying to the vial.

2ml Clear HPLC Screw Vials are preferentially used on instruments of the following manufacturers: Jasco, Perkin Elmer, Shimadzu, Varian, Waters, etc., or General Storage. Factory Directly Supply 2ml Clear HPLC Screw Vials over 15 Years Exporting Experience.

Aijiren’s exclusive adhesive-free bonding process does not require the introduction of adhesives. The septum retains the excellent resilience properties of silicone rubber or silicone. It is softer than the septum of the bonding process and is convenient for the needle of the autosampler Better penetration.

Clear 2ml HPLC Vials and closures are universally suitable on most autosamplers. Due to their artificially reduced cap-height screw caps, N9 doesn’t have a standardized thread design.

18mm screw neck metal screw cap is made of magnetic metal, this cap is mainly used for seal 18mm screw GC headspace vial. PTFE septa can meet multiple punctures.
Steel Magnetic caps tolerate high temperatures and are suitable for use with the CTC/LEAP/Gerstel autosamplers.

Crimp Vials squeeze the septum between the rim of the glass vial and the crimped aluminum cap. This forms an excellent seal preventing evaporation. The septum stays seated during piercing by the autosampler needle. The crimp cap vial requires crimping tools to carry out the sealing process. For low volume settings, manual crimper tools are the choice. For high volume settings, automated crimpers are available.

3.Center automatically with a flat bottom and mandrel interior
4.Type I borosilicate glass

8-425 screw thread caps and vials are suitable for Agilent, AB Sciex, Brukers, Techcomp, PerkinElmer, ThermoScientifics, Shimadzu, Waters, CTC autosampler and other rotating or robotic arm samplers and autosamplers.

These glass vials are used in the environmental industry. Available in Flat bottom.
Clear. Type 1, Borosilicate, 33 Expansion. Also available in Amber, 51 Expansion.
Various sizes and capacities are available. Caps are sold separately.
(24-414 finish available by special order).

2ml Amber Screw HPLC Vials, caps, septa, and inserts working as a whole to prevent sample degradation and loss of samples caused by evaporation. Screw thread closures N9 (9mm) 2ml vials and closures are universally suitable on most autosamplers, convenient in handling and available in a broad selection of different cap colors and septum materials.

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.

The Aijiren hand crimper provides a consistent and dependable seal that allows secure vial closure each and every time. The high-quality construction is engineered for durability and long life to provide a smooth and simple operation. The manual crimper is suitable for standard laboratory bottles and seals with aluminum caps. Compared with the metal handle design, the ergonomic arc-shaped handle provides higher hand comfort during use. The bottom handle can be held steadily, without the need for “extra” squeezing. The easy-to-see adjustment knob is located on the head of the crimping pliers, so you can easily determine when the desired crimp setting is reached.

Aijiren offers innovative high-recovery vials for comprehensive collection, automated handling, and storage, with the subsequent maximum retrieval of high-value samples. High recovery vials offer precision vials made from low expansion borosilicate glass and are designed with a unique interior bottom, solid glass bottom of a Microliter-Vial with an inner cone, allowing for maximum retrieval of contents by a syringe. High Recovery Vials Reduce Residual Product Waste by 99%. high recovery vials are optimal for manual and automated compound or biological sample applications.

PTFE/Silicone septa are most popular for HPLC applications, and Pre-slit septa are easier to pierce with needles.
Usually, the cap color is clear or blue, other special colors can be also produced accordingly.
