Choose the right 2ml crimp vial: The easy-to-fill wide-necked vial requires a 6 mm diameter micro-insert. The sample and volume can be identified by the scale provided on the crimp vial and a stickable patch, which can be obtained without a separate insert Maximum sample extraction volume.
11mm crimp top vials are designed to provide superior performance in limited volume applications where recovery of the vial contents is the main consideration. These vials are designed to be used with 11mm aluminum crimp top seals.
Types of 2ml crimping chromatography vial septa: PTFE/silicone, natural rubber/TEF septa, single-seam septa are available. The three-layer spacer of natural rubber/red butyl/TEF combines the good physical properties of Nat. Rubber with butyl chemistry (resealable).
The bottom of the 2ml crimp vial is even and flat to ensure the safety of the blade. The sample vial has a stickable patch, and the graduations are 0.5, 1.0 and 1.5mL. The Aijiren crimp top vial has a color-coded gradient pasteable patch, and the sample vial with a crimp surface of 11mm requires an aluminum sealing cap.
Use Aijiren 11 mm glass crimp top vials with aluminum crimp seal caps. These high-quality 11 mm glass vials are 2 ml, 12 x 32 mm, and fit most brands of autosamplers. Made of high-quality 33-level expanded borosilicate transparent material (Type 1, Type A).
The wide opening of the 2ml crimp vial is easier to fill, and is suitable for most autosamplers that can accommodate 12x32mm sample vials. It is made of high-quality No. 33 expanded borosilicate transparent glass type 1, grade A or 51A amber glass.
2ml crimp vial is a standard sample vial for GC and HPLC. The sample port 40% larger than the standard narrow-mouth vial makes filling easier, improves the accuracy of the autosampler needle, and provides the tightest seal. The precision-shaped neck can improve the processing capacity of the autosampler.
The neck finish of the 2ml crimp vial allows the use of standard aluminum seals. Surface treatment eliminates the need for crimping or capping off. Designed for use in Aijiren and other autosamplers. Choose from clear or amber Type I borosilicate glass.
The Aijiren Crimp vials are the standard vials for GC and HPLC. The crimp caps provide the tightest seal, reducing the chance of sample evaporation. The 12X32 mm crimp vials and 11mm Aluminium crimp caps are economical, save your cost and easy to use with crimping tools.
2ml crimp sample vial squeeze the septum between the edge of the glass vial and the crimped aluminum cap. This forms an excellent seal against evaporation. During the autosampler needle piercing process, the septum remains in place. Crimping cap vials requires crimping tools to perform the sealing process.
The crimping of the top sample bottle requires a painted aluminum crimp seal, which is relatively inexpensive and provides the best sealability for long-term storage when properly assembled. The crimp seal cannot be reused. It needs to be sealed with 11mm Hand Crimper and unsealed with Hand Decrimper.
Crimp Vials are manufactured from Type 1 borosilicate glass, available in clear or amber, or from Polypropylene. Requires a crimper and decapper. Excellent for long term storage. Deactivation and MS Certification is also available.
All Aijiren vials are very suitable for autosamplers and have good chemical compatibility and ultra-high cleanliness. The crimp top sample bottle is currently the most commonly used gas sampling bottle on the market. The sample bottle with a volume of 2ml is especially suitable for laboratory use. At the same time, the bottom of the sample bottle is designed as a round bottom, so it has a flat bottom function and is compatible with automatic sampling equipment.
The 11mm crimp cap is sealed by squeezing the septum between the edge of the glass vial and the crimped aluminum cap. This is an excellent seal to prevent evaporation. Crimping cap vials requires crimping tools to perform the sealing process.
As far as the autosampler compatibility is concerned, the crimping cap N11 is also universally applicable. It can be sealed and unsealed with the 11mm Hand Crimper and 11mm Hand Decrimper produced by Aijiren.
The Aijiren sample vial has excellent sealing performance, which can effectively avoid sample evaporation. The vial and the corresponding 11 mm aluminum cap can be easily and quickly combined with the jaw capping tool. The vial can withstand heat and pressure, and can also be used for chemical reactions. Especially for vials with white open caps and thick PTFE / silicone septa, they can be used as anhydrous and oxygen-free reaction vials.
Aijiren’s Crimp Top Vials have a 40% larger opening than standard opening aluminum seal vials. Manufactured of Clear, Type 1 Class A or Amber, Type 1 Class B, borosilicate glass. Vials offer a standard graduated write-on patch for easy filling and identification
2ml Crimp Autosampler Vial with insert is larger and wider mouth than 9mm screw sample vial. 2ml crimp autosampler vials have approximately a 40% wider mouth opening than standard opening vials. The large opening reduces the risk of bent autosampler needles during sampling.
