Autosampler Vial’s Cap and Septa

The snap vials are less prone to breakage during decapping because more glass is used in the neck of the vial. The snap seal neck finish is compatible with either crimp or snap seals and no special tools are required to remove the cap. These vials are recommended for short-term sample storage and non-volatile samples because the seal is not as secure as a crimp or screw thread seal.

A crimping tool is required to seal caps and a decrimper or decapper is required to remove the seals. Several types of hand crimpers are available including the adjustable precision crimpers that Chromatographic Specialties offers. Adjustable hand crimpers feature an adjustable stop on the handle to provide consistent seal tightness every time. Adjusting the hex screw inside the steel crimper jaws will also alter the amount of crimp. Achieving a good crimp is crucial because overcrimping can cause septum coring, bent needles and create a larger loose seals and sample evaporation.

Chromatography vial is a glass vial used by automatic samplers and headspace samplers such as liquid chromatography, gas chromatography, mass spectrometry, etc. for chromatographic automatic sampling.  10-425 Screw Glass vial for autosampler instrument is made of borosilicate glass.

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

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.

The size of 2ml 8mm Clear Glass Vial is 12 x 32mm. The precise handling of the bottleneck enables the robot arm to operate efficiently. The 2ml 8mm Clear Glass Vial has an opening 40% larger than the standard narrow-mouthed vial to prevent problems with the syringe. The special thread design ensures a consistent seal.

Aijiren produces headspace vials for the convenience of gas chromatographic analysis. Gas chromatographic analysis requires heating and other methods to vaporize the liquid in the vial and extract gas for detection and analysis through an automatic injection needle. Gas chromatograph requires the vial to have good airtightness and heat resistance. With strong stability and large capacity, the crimp top headspace vials produced by Aijiren perfectly meet these conditions.

Screw thread vials and caps provide low evaporation, reusability, less hand injury during manipulation than crimp seals and require no special tools. All screw threads vials and caps are differentiated by their thread finish as defined by the Glass Packaging Institute, GPI. For screw thread vials, a two part number is assigned. For example, 8-425 neck finish represents a vial with a diameter of 8 mm across the outside of the threads and a thread style of 425. Screw thread vials and caps are more expensive than crimp seals.

The material of the headspace bottle is borosilicate glass with low extraction rate, which has low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. The headspace sample bottle is suitable for headspace analysis of volatile solids and gases.

The 0.3ml PP Clear or Amber Micro Vial with a 9mm Screw Neck is a versatile and compact solution for laboratory sample storage and analysis. These micro vials are made of high-quality polypropylene (PP) material, ensuring excellent chemical resistance and sample protection. Available in clear or amber options, they offer visibility and light protection for different sample types.

Screw cap vials are universal. When the cap is screwed on, a mechanical force is applied that compresses the septum between the rim of the vial and the cap. Screw caps provide an excellent seal and mechanically hold the septum in place during piercing. No tools are required for assembly.

Screw cap vials are a practical packaging solution for sample-size health, beauty, and pharmaceutical products. Glass screw cap vials are impermeable and don’t undergo chemical leaching, so your products stay pure. Uses for Screw Cap Vials. Use glass screw cap vials to package sample products or as full-size product packaging options.

Chemical oxygen demand is a vital test for assessing the quality of effluents and waste waters prior to discharge. The Chemical Oxygen Demand (COD) test predicts the oxygen requirement of the effluent and is used for monitoring and control of discharges, and for assessing treatment plant performance. The impact of an effluent or waste water discharge on the receiving water is predicted by its oxygen demand. This is because the removal of oxygen from the natural water reduces its ability to sustain aquatic life. The COD test is therefore performed as routine in laboratories of water utilities and industrial companies.
